Term-PAK INTRODUCTION

Thanks for purchasing TERM-PAK!

TERM-PAK is a collection of two very powerful software packages for designing and fabricating low-frequency loudspeaker enclosures.

Enclosure Design

TERM-PRO is the most popular low-frequency loudspeaker enclosure design program for the mobile electronics industry. Designed specifically with the installer in mind, TERM-PRO is comprehensive, yet simple to operate. Even beginners will be able to design perfect enclosures with just a few simple mouse clicks.

Experienced users will appreciate the program’s powerful command structure and flexibility.

Enclosure Fabrication

TERM-CAD 3D is a revolutionary new software package designed exclusively for fabricating low-frequency loudspeaker enclosures. The program features a variety of 3D editing commands that makes it easy to design and save blueprints for enclosures. Optional Box Pack libraries are also available which contain a multitude of pre-designed enclosures for various vehicle makes and models. Other outstanding features include our unique Isographic 3D Viewport which allows the user to view the design from virtually any angle! The program even includes a command that animates the design so that you can “walk around” the enclosure in virtual space.

UNPACKING

TERM-PAK software contains the following items:

  • User’s manual

  • Distribution disk

WHAT YOU NEED TO KNOW

This manual assumes your familiarity with (1) MS-DOS and the utilities that came with your computer, and (2) your mouse and its installation and operation.

A fundamental understanding of the terminology described in the DEFINITIONS section of this manual is also highly recommended.

ABOUT THIS MANUAL

This manual is a reference manual for TERM-PAK and is not intended to be a tutorial on how to design and fabricate enclosures. The remainder of the manual contains sections to help you start using TERM-PAK.

CONSIDERATIONS

IMPROVING PERFORMANCE

TERM-PAK utilizes algorithms that are computationally intensive. This section suggests ways to improve the performance of your system.

EMM386 (DOS only)

If you are using EMM386 as your expanded memory manager, RAM must appear on the EMM386 command line in your CONFIG.SYS file. For example ...

device=c:\dos\emm386.exe 512 AUTO RAM

In this example, EMM386 will allocate 512K for use as EMS memory. See your DOS documentation for additional information.

QEMM (DOS only)

Do not use QEMM’s STEALTH mode. (Stealth mode may be disabled by running QSETUP from the QEMM subdirectory.) You will need to run OPTIMIZE again if you make any changes during QSETUP. See your QEMM documentation for additional information.

NOVELL NETWARE

If you are running Novell Netware on your system, version 3.01 or newer MUST be used.

Simply install TERM-PAK to the file server normally. TERMPAK will be accessible from all workstations that have access rights to the TERM-PAK subdirectory. However, only one workstation may use the program at a time. A mult-instancing version of TERM-PAK is available for an additional fee. Contact the factory for pricing information.

LANTASTIC

If you are running Lantastic on your system, version 4.10 or newer MUST be used.

Install TERM-PAK to the desired hard drive THROUGH the redirector. TERM-PAK will be accessible from all computers that access this hard drive with the SAME drive letter designation as specified during the installation process (the Destination drive).

For example, if you install TERM-PAK onto drive F, all computers that access this drive as drive F will be able to access the TERM-PAK program. Computers that access drive F with another drive letter designation will NOT be able to access the TERM-PAK program. (A security error will result.)

Refer to the REDIRECTOR section of your Lantastic documentation for additional information.

Term-PRO OPERATION

SCREEN LAYOUT

Main Menu Bar

The top line of the screen is the MAIN MENU BAR. This line presents a list of titles that indicate the types of selections available in each pull-down menu. Selecting a title from the main menu bar causes TERM-PRO to drop down a list of selections available for that title.

Program Module Tabs

The PROGRAM MODULE TABS are located immediately below the Main Menu Bar. These tabs are used to switch between the different program modules within TERM-PRO.

Toolbar

The TOOLBAR provides an easy and convenient way to select or configure commonly used program parameters. For a detailed description of each these buttons, refer to the TOOLBAR section in each chapter.

Dialog Line

The DIALOG LINE is located at the very bottom of the screen. TERM-PRO uses this line in conjunction with DIALOG BOXES to communicate with the user.

Program Selection Tabs

The PROGRAM SELECTION TABS are located at the bottom right hand corner of the screen. These tabs are used to switch

between various Wayne Harris Enterprises’ programs.

USING THE MOUSE

The commands in this manual often instruct you to use your mouse to perform certain functions on the graphics screen. The button most often used is the PICK button. This usually is the mouse’s left button. You use this button to pick a menu selection, click on a dialog box selection, or select an entity on the graphics screen.

Mouse Pointers

The mouse pointer (or cursor) is usually a small arrow. However, the mouse pointer changes to other shapes during several operations.

When the mouse pointer is positioned within the title area or “handle” of a dialog box window, the mouse pointer becomes an arrows symbol.

When you give TERM-PRO a time-consuming command, the mouse pointer becomes an hourglass symbol.

Mouse Operation

The word CLICK is used frequently throughout this manual. When referring to a mouse button it means “press and release” the PICK button. DOUBLE CLICK means “press and release” the PICK button twice in quick succession. When the term DRAG is used, you must hold down the PICK button while you move the cursor to another location.

The MOUSE driver program (MOUSE.EXE or MOUSE.SYS) should be loaded into memory before you operate TERM-PRO. (Refer to your mouse documentation for additional information.) If you are running TERM-PRO from within Windows 95, the mouse driver is not required because Windows 95 provides mouse support automatically.

Mouse Buttons

To initiate an action in TERM-PRO, the user is required to click a mouse button. The function of each mouse button is defined as follows (refer to figure 4.3) ...

Cancel

Pick

Cancel

Button

3 Button Mouse 2 Button Mouse

Figure 4.3 - Mouse Button Functions

Pick Button

The PICK button is used to make a selection or enter a data point. (Pressing ENTER on the keyboard generally produces the same result as clicking the PICK button.)

Cancel Button

The CANCEL button aborts an operation. (Pressing the ESC key on the keyboard generally produces the same result as clicking the CANCEL button.)

PULL DOWN MENUS

TERM-PRO uses PULL DOWN MENUS so that it will work in a similar fashion to other software packages that have adopted pull down menus as their user interface. The MAIN MENU BAR presents a list of titles that indicate the types of selections available in each Pull Down Menu.

Clicking on a Main Menu Bar title pulls down a sub-menu full of items. Clicking on a menu item tells the program to do something. TERM-PRO uses the Dialog Line and Dialog Boxes to tell the user what it wants.

Hot Keys

Any underlined letter on a pull-down menu item is a HOT KEY.

You can select the item by holding down the “Alt“ key while you press the Hot Key.

DIALOG BOXES

TERM-PRO’s DIALOG BOXES offer a convenient way to view and adjust certain program settings.

Dialog Boxes will also pop up whenever TERM-PRO needs immediate input from the user or whenever vital information needs to be displayed.

Title Area or “handle”

TermPRO
Are you sure you want to exit? NoYes

Figure 4.5 - Sample Dialog Box

To reposition a Dialog Box (if it is covering an area of the screen you would like to see), move the mouse pointer to the title area of the Dialog Box and hold down the left mouse button. (The mouse cursor will change shape when the mouse pointer is located within the title area or “handle” of the Dialog Box.) Moving the mouse now drags the Dialog Box; releasing the mouse button leaves the Dialog Box in its new location.

VARIOUS OTHER CONTROL ELEMENTS

Spin Buttons

Lock buttons are used to prevent TERM-PRO from automatically changing the data value in a Data Entry Field. When you press the lock button that corresponds to a Data Entry Field, the value of that field is locked in place and will not change during calculations.

Data Entry Field

Data entry fields are used to display and edit data. Data Entry Fields are always white with a black border. To edit the data in a Data Entry Field, position the mouse pointer over the desired field and click the PICK button on the mouse. Type in the new value and then press ENTER. To abort the edit process, press the ESC key.

Spin Buttons

Spin Buttons are used to increment or decrement the value displayed in the Data Entry Field by a specified amount. To decrement the value displayed in the Data Entry Field, press the down arrow key. To increment the value, press the up arrow key.

Radio Buttons

Radio Buttons are used to select a specific item from a group of items. Only one selection can be active at a time. To select an item, position the mouse pointer over that item and then click the PICK button.

Check Boxes

Check Boxes are used to enable or disable certain features. To enable a feature, position the mouse pointer over the check box that corresponds to that feature and click the PICK button.

Term-PRO EXAMPLES

One of the fastest ways to learn TERM-PRO is to jump right in and play

with the program. Then, when you’re familiar with the basic operation of the program, you should study each command thoroughly to fully realize the potential the program has to offer.

STARTING TERMPRO

To start TERM-PRO, type “TERMPAK” and then press ENTER. The program will default to the DRIVER LIBRARY module.

Your screen should look similar to the one shown in Figure 5.1.

LOADING A DRIVER

To load a driver, click the mouse on the Library Selector Tab that has the same first letter as the driver you would like to load. For

example, if you want to load a Rockford driver, click on the “R” Selector Tab.

Drivers beginning with the letter “R” will appear in the Driver List Box. Press the Up or Down arrow keys on the scroll bar to scroll through the list of drivers. The driver under the highlight bar is the currently selected driver. Position the highlight bar over “Rockford Fosgate RFP-1410.” It is now the currently selected driver.

PROFILE ENCLOSURE DESIGN

Click the PROFILE BOX program module tab to continue with the example. Your screen should look like the one shown in Figure

5.3.

At this point, you should select the type of enclosure you would like to design. To select an enclosure type, press the Enclosure Selector button.

After pressing the ENCLOSURE SELECTOR button, the following enclosure selections will be displayed ...

Position the mouse pointer over VENTED and then click the Pick button.

At this point, we have selected our driver (Rockford Fosgate RFP-1410) and the type of enclosure we would like to design (Vented). Now we are going to actually design the enclosure.

To design a profile enclosure, simply press a Profile button that best describes the customer.

For a normal customer, press the Normal button. TERM-PRO will calculate the required box volume and tuning frequency. This information will be displayed in the Profile Design Information panel.

TERM-PRO will also display a score that represents how well the current design will work for the specified customer profile. The higher the score, the better suited the design is for the selected customer profile.

If you would like to see what the predicted frequency response looks like for the design, press the PLOT button. Your screen should look something similar to the one shown in figure 5.8.

Now would be a good time to play with the Trace Enable buttons on the Toolbar. Press the Power button. The power handling for the system will now be displayed. Un-press it and the trace will go away. Repeat this exercise for SPL.

All plot information is calculated each time you press the Plot button. However, the trace for a specific plot type will only be visible if that plot

type’s Trace Enable button is depressed.

Try pressing the Xhair button. This enables TERM-PRO’s xhair. Move the crosshair around. Press ESC on the keyboard or click the cancel key on the mouse to continue.

VENT DESIGN

Now that we have our required enclosure volume and enclosure tuning frequency, all that is left is to design the vent.

Select the VENT DESIGN program module tab. Your screen should look something similar to the one shown in figure 5.9.

Make sure the BACK CHAMBER tab is selected. (Simple Vented enclosures only have a back chamber.) The calculate box volume and tuning frequency will be displayed in the Vent Design data

entry fields. These values are locked by default and don’t usually need to be changed.

Change the Vent Diameter and note how the Vent Length changes automatically to maintain the proper tuning frequency. Note how the Vent Air Velocity changes as well.

CUSTOM BOX DESIGN

TERM-PRO’s CUSTOM BOX DESIGN module lets “power users” control all aspects of system design. To activate the Custom Box Design module, select the Custom Box program module tab. You screen should look similar to the one shown in figure 5.10.

Try experimenting with the Back Chamber Volume data field. Note how the recommended tuning frequency changes with different box volumes. To plot the results of the most recent design, press the Plot button. Better yet, press the Plot Lock button. Now, whenever you make a change to the design, the results will be

Figure 5.11 - Plot Button

updated on the graph instantaneously. This is seriously cool! To clear the graph area, press the Clear button on the Toolbar.

Normally, TERM-PRO calculates unknown values whenever you specify a known value. For instance, if you specify the desired box volume, TERM-PRO will automatically calculate the recommended tuning frequency. To override this feature, you can lock data fields. This prevents TERM-PRO from changing them during calculations. To lock a data field, press the lock button that corresponds to that data field.

Figure 6.11 - Printer Color Mapping Dialog Box

The Printer Color Mapping dialog box is used to assign screen colors to printer colors. This is necessary for several reasons. First, the HP 550C color printer is only capable of printing 8 colors whereas TERM-PRO uses 16 colors. Secondly, you generally want to print white screen colors in black on the printer and leave black screen colors white on the printer. Color mapping is the process you use to address both of these issues.

To map a screen color to a printer color, use the following procedure ...

  • First, select the screen color you would like to map from the column of 16 buttons on the left of the Color Mapping dialog box. These buttons correspond to the 16 screen colors used in TERM-PRO. (The currently mapped printer color will be pointed to by a line with an arrow.)

  • Next, choose the printer color you would like to assign to the selected screen color from the column of 8 buttons on the right side of the Color Mapping dialog box. These buttons correspond to the 8 colors the HP 550C can print.

Select Ok when color mapping is complete. Select Default to use the default settings. Select Cancel to abandon any changes that were made.

VENT SELECTOR TABS

These tabs are used to switch between the front and back chambers of the enclosure during the vent design process.

Figure 12.2 - Chamber Selector Tabs

Vented Highpass enclosures have vents in the back chamber only. Single Reflex (BP4) Bandpass enclosures have vents in the front chamber only. Dual Reflex (BP6) Bandpass enclosures have vents in both the front and back chambers.

Back Chamber Tab

Select this tab to design vents for the back chamber of the enclosure. Information pertaining to the current vent design for the back chamber will be displayed in the VENT DESIGN data entry fields (discussed later in this chapter.)

Front Chamber Tab

Select this tab to design vents for the front chamber of the enclosure. Information pertaining to the current vent design for the front chamber will be displayed in the VENT DESIGN data entry fields (discussed later in this chapter.)

Options Tab

Select this tab to specify default options for the Vent Design module. Refer to the Vent Design Options section later in this chapter for a detailed overview of the options available and their uses.

VENT AIR VELOCITY BARGRAPH

This bargraph indicates the velocity of the air moving inside the vent as a percentage of the speed of sound (Mach).

Figure 12.4 - Vent Air Velocity Bargraph

When designing a vent, you should try to keep the vent air velocity value as low as possible. Otherwise, vent turbulence and other audible artifacts may be heard.

Ideally, you would use a vent with a very large surface area to keep the vent air velocity low. This would work because vent air velocity is directly related to the area of the vent being used. Unfortunately, the larger the vent area, the longer the vent length needs to be for a given tuning frequency. In reality, large area vents usually need to be so long that they’re just not practical. Because of this, many designers are forced to trade-off vent air velocity for vent length.

The VENT AIR VELOCITY bargraph is the tool you use to determine what is acceptable and what is not.

Typically, audiophiles recommend keeping the vent air velocity below 5% of the speed of sound. This is not very realistic in autosound installations where enclosure volumes are usually pretty small. At Wayne Harris Enterprises, we have determined that a vent air velocity as high as 12% is acceptable for most installations. With an Aeroport, the vent air velocity can be as high as 20% without running into significant problems.

VENT DESIGN DATA ENTRY FIELDS

These VENT DESIGN DATA ENTRY FIELDS are used to display and edit vent design information for the currently selected enclosure chamber.

Chamber Volume

This value represents the NET air volume for the currently selected chamber of the enclosure in cubic feet or liters. You will usually not need to change this value as it is calculated elsewhere in the program.

This field is locked by default.

Chamber Tuning Frequency

This value represents the tuning frequency for the currently selected chamber of the enclosure in Hz. You will usually not need to change this value as it is calculated elsewhere in the program. This field is locked by default.

Vent Quantity

This value represents the quantity of vents in the currently selected chamber. TERM-PRO supports multiple vents. Each chamber can also have a different number of vents if so desired.

VENT TYPE SELECTOR

TERM-PRO supports three different vent types. To select the desired vent type, position the mouse pointer over the desired Vent Type radio button and click the Pick button on the mouse.

VENT DESIGN DATA ENTRY FIELDS

The VENT DESIGN data entry fields are used to display and edit the dimensions of the vent being designed.

Inside Diameter

This field represents the inside diameter of the vent in inches or centimeters for CIRCULAR vents and AEROPORTS. If you enter a value into this field, TERM-PRO will calculate the vent length required for the specified chamber volume and tuning frequency. The Vent Area will also be calculated.

Width

This field represents the width of the vent in inches or centimeters for RECTANGULAR vents. If you enter a value into this field, TERM-PRO will calculate the vent length required for the specified chamber volume and tuning frequency. The Vent Area will also be calculated.

SCREEN LAYOUT

Main Menu Bar

The top line of the screen is the MAIN MENU BAR. This line presents a list of titles that indicate the types of selections available in each pull-down menu. Selecting a title from the main menu bar causes TERM-CAD to drop down a list of selections available for that title.

Toolbar

The TOOLBAR provides an easy and convenient way to select or configure commonly used program parameters. By pressing the appropriate Toolbar button, the user may change the current drawing color, cycle the active layer through the layers that are

turned “on”, select the active view, toggle the grid snap on or off, change the dot grid spacing, display the last view, and toggle through the different coordinate display modes. For a detailed description of each these buttons, refer to the TOOLBAR section in this chapter.

Status Line

The STATUS LINE contains a combination of Toolbar buttons, text, and numbers. Here you find information about how TERMCAD is set up and how it reacts when you issue certain commands. Figure 4.1 shows the Active Color, Active Layer, Active View, Snap Mode, Dot Grid Spacing, Active Coordinate Display mode, and the Coordinate Readout for the Active Coordinate mode.

Program Selection Tabs

The PROGRAM SELECTION TABS are located at the bottom right corner of the screen. These tabs are used to switch between various Wayne Harris Enterprises’ programs.

Dialog Line

The DIALOG LINE is located at the very bottom of the screen. TERM-CAD uses this line in conjunction with DIALOG BOXES to communicate with the user.

Viewports

TERM-CAD uses 4 viewports to display the current design.

The TOP VIEW viewport displays the design as seen from above. The FRONT VIEW viewport displays the design as seen from the front, and the SIDE VIEW viewport displays the design as seen from the side. The ISOGRAPHIC 3D viewport allows the user to view the design from any side. The actual viewpoint may be changed by

TOP VIEW

Figure 4.2 - Viewport Relationships

using the ISOGRAPHIC 3D VIEWPORT CONTROL TOOLBAR.

Active Viewport

During drawing and editing operations, the active viewport will be indicated by the presence of PAN BARS. (The active viewport is the viewport where you are allowed to move the crosshair in two axis.) Pan Bars consist of two white rectangles that encompass the active viewport. The area between these rectangles is the PAN BAR CONTROL AREA.

Pan Bars

Pan Bars provide a convenient means for panning the active viewport during drawing and editing operations. Simply position the crosshair within the Pan Bar Control Area and click the PICK button on the mouse. The point under the crosshair will become the new viewport center.

See DISPLAY / PAN in Chapter 10 and KEYBOARD COMMANDS in this chapter for related command information.

button. (See KEYBOARD COMMANDS in this chapter for additional information.)

US ING THE MOUSE

The commands in this manual often instruct you to use your mouse to perform certain functions on the graphics screen.

The button most often used is the PICK button. This usually is

the mouse’s left button. You use this button to pick a menu selection, click on a dialog box selection, or select an entity on the graphics screen.

Mouse Pointers

The mouse pointer (or cursor) is usually a small arrow. However, the mouse pointer changes to other shapes during several operations.

When the mouse pointer is positioned within the title

area or “handle” of a dialog box window, the mouse pointer becomes an arrows symbol.

When you give TERM-CAD a time-consuming

command, the mouse pointer becomes an hourglass symbol.

When TERM-CAD wants you to select an entity on the graphics screen, a pick box pointer will be displayed.

During drawing operations, TERM-CAD will display a standard crosshair pointer.

While placing text, TERM-CAD will display a rectangular text box pointer that is equal in size to the maximum extents of the entered text.

The word CLICK is used frequently throughout this manual.

PICK button twice in quick succession. When the term DRAG is used, you must hold down the PICK button while you move the cursor to another location.

Mouse Buttons

To initiate an action in TERM-CAD, the user is required to click a mouse button. The function of each mouse button is defined as follows (refer to figure 4.17) ...

Pick Button

The PICK button is used to make a selection or enter a data point. (Pressing ENTER on the keyboard generally produces the same result as clicking the PICK button.)

Pick Cancel Active
Button View

3 Button Mouse 2 Button Mouse

Figure 4.17 - Mouse Button Functions

Cancel Button

The CANCEL button aborts an operation. (Pressing the ESC key on the keyboard generally produces the same result as clicking the CANCEL button.)

Active View Button

This key cycles the Active View between the Top, Front, Side and Isographic 3D viewports. The currently selected viewport will be indicated by the presence of Pan Bars. The Active View will also be indicated on the Toolbar. (If your mouse

only has 2 buttons, you must use the “V” key as described in the KEYBOARD COMMANDS section of this chapter.)

Navigating with the Mouse

If you have a mouse: first, see if a mouse pointer is visible on the screen, and that it moves when you move the mouse. If so, then the mouse works. If this isn’t the case, refer to your mouse documentation regarding mouse driver installation.

The MOUSE driver program (MOUSE.EXE or MOUSE.SYS) should be loaded into memory before you operate TERM-CAD. (Refer to your mouse documentation for additional information.) If you are running TERM-CAD from within Windows 95, the mouse driver is not required because Windows

95 provides mouse support automatically.

PU LL DOWN MENUS

TERM-CAD uses PULL DOWN MENUS so that it

will work in a similar fashion to other software

packages that have adopted pull down menus as their user

interface. The MAIN MENU BAR presents a list of titles that

indicate the types of selections available in each Pull Down Menu. Clicking on a Main Menu Bar title pulls down a sub-menu full of items. Clicking on a menu item tells the program to do something. TERM-CAD uses the Dialog Line and Dialog Boxes to tell the user what it wants.

Hot Keys

Any underlined letter on a pull-down menu item is a HOT KEY.

You can select the item by holding down the “Alt“ key while you press the Hot Key.

DIALOG BOXES

TERM-CAD’s DIALOG BOXES offer a convenient way to view and adjust certain program settings.

Dialog Boxes will also pop up whenever TERM-CAD needs immediate input from the user or whenever vital information needs to be displayed. To reposition a Dialog Box (if it is covering an area of the screen you would like to see), move the mouse pointer to the title area of the Dialog Box and hold down the left mouse button. (The mouse cursor will change shape when the mouse pointer is located within the title area or “handle” of the Dialog Box.) Moving the mouse now drags the Dialog Box; releasing the mouse button leaves the

Figure 6.15 - Printer Color Mapping Dialog Box

The Printer Color Mapping dialog box is used to assign screen colors to printer colors. This is necessary for several reasons. First, the HP 550C color printer is only capable of printing 8 colors whereas TERM-CAD 3D uses 16 colors. Secondly, you generally want to print white screen colors in black on the printer and leave black screen colors white on the printer. Color mapping is the process you use to address both of these issues.

To map a screen color to a printer color, use the following procedure ...

  • First, select the screen color you would like to map from the column of 16 buttons on the left of the Color Mapping dialog box. These buttons correspond to the 16 screen colors used in TERM-CAD 3D. (The currently mapped printer color will be pointed to by a line with an arrow.)

  • Next, choose the printer color you would like to assign to the selected screen color from the column of 8 buttons on the right side of the Color Mapping dialog box. These buttons correspond to the 8 colors the HP 550C can print.

Select Ok when color mapping is complete. Select Default to use the default settings. Select Cancel to abandon any changes that were made.

Figure 6.17 - Import DXF List Box

4 Position the mouse pointer over the desired DXF file name and DOUBLE CLICK the PICK button.

TERM-CAD utilizes a highly specialized database format. Because of this, some DXF files may be incompatible with TERM-CAD.

For example, DXF 3D surfaces must always contain exactly 4 sides. TERM-CAD, on the other hand, will support N sided 3D surfaces. This means that a 6 sided 3D surface in TERM-CAD would actually be represented by two 4 sided 3D surfaces in a DXF file. When importing this file, TERM-CAD would treat the object as two 4 sided 3D surfaces instead of a single 6 sided surface.

EDIT / POLARITY

FUNCTION:

Reverses 3D surface polarity.

REMARKS:

Use this command to reverse the polarity of a 3D surface. The polarity of a 3D surface determines whether the surface is facing towards the camera or away from the camera. This, in turn, affects

the “brightness” of a face when it is shaded in the Isographic 3D viewport. TERM-CAD 3D uses sophisticated algorithms to automatically polarize 3D surfaces for you. However, in some situations, the program may not be able to identify the correct polarity for a 3D surface. When this occurs, a surface that should be “bright” might be “dark” or vice-versa. This indicates that the polarity of the surface is probably reversed. Use this command to correct the surface polarity.

OPERATION:

1 Select EDIT from the Main Menu bar.

2 Select POLARITY from the EDIT pull-down sub-menu. The program will prompt, “Select the item type ...” and the POLARITY sub-menu will display the available choices.

OPERATION:

1 Select OPTIONS from the Main Menu bar. The following pull down sub-menu will be displayed.

OPTIONS / LAYERS

FUNCTION:

Specify layer and color options.

REMARKS:

Use the Layer and Color Options dialog box to select the active layer, turn layers on or off, and specify the color to be used during drawing operations.

Layers may be thought of as “transparent sheets” that can be stacked on top of one another. TERM-CAD supports sixteen individual layers.

Refer to the Layer and Color Options dialog box shown in Figure

11.2.

This dialog box contains three columns of buttons. The left column is used to select the ACTIVE LAYER, the middle column is used to turn the individual layers ON or OFF, and the right column is used to specify the COLOR assignment for the active layer.

The ACTIVE LAYER is the “sheet” where subsequent drawing will take place. For instance, if the Drawing layer is the active layer, then everything you draw will be placed on this layer or “sheet.” In Figure 11.2, the Drawing layer is the active layer.

Layers may be turned ON or OFF individually. This is handy because it lets you select only those layers you want to display. For instance, if you put your dimensioning information on the Dimension layer, then you could display that information by turning the Dimension layer ON, or you could hide the dimensioning information by turning the Dimension layer OFF.

When a layer is turned OFF, the information it contains is not lost. It is just not being displayed. To see the information again, simply turn the layer back ON.

The ACTIVE COLOR is the color that will be used

when subsequent drawing operations occur. Each layer

“remembers” the color you assign to it.

OPERATION:

1 Select OPTIONS from the Main Menu bar. 2 Select LAYERS from the OPTIONS pull-down sub-menu. The following dialog box will be displayed ... 3 Use the mouse to select the active layer, turn individual layers

FAB / PANELIZE

FUNCTION:

Convert 3D faces into panels.

REMARKS:

Use this command to convert 3D faces into panels. Normally, when you load, save, or design an enclosure, you only work with

external dimensions. This is because you don’t know what type of construction material or material thickness you are going to use until you actually build the box. (The type of material used as well as the thickness will vary from install to install.) This command lets you convert the faces in your design into actual panels with a thickness equal to that specified in the Thickness section of material selection.

Inches = mm / 25.4

Example: A piece of wood is 300 mm long. What is its length in inches? Inches = 300 / 25.4 = 11.81

Converting Cubic Inches to Cubic Feet

Cubic Feet = Cubic Inches / 1728

Example: An enclosure has an internal volume of 2500 square inches. What is its internal volume in cubic feet? Cubic Feet = 2500 / 1728 = 1.456

Area Equations

Area (rectangle) = Length x Width Area (triangle) = 1/2 Length x Width Area (circle) = 3.14 x Radius x Radius Area (circle) = .785 x Diameter x Diameter

Volume Equations

Volume (rectangular box) = Area (of one side) x Depth Volume (triangular enclosure) = Area (triangle) x Depth Volume (cylinder) = Area (circle) x Depth
