How to Execute Commands

Choose between the following five ways to execute commands in the Viewlogic tools.

• Pull-down menus
  
  
• Hotkeys
  
  
• Toolbar buttons
  
  
• Command line
  
  
• Right mouse button
  
  

This tutorial refers to the pull-down menus in most cases. To use the pull-down menus, click and drag with the left mouse button.

Hotkeys

You can use the keyboard to execute various commands. These “hot keys” appear next to the commands in the first four pull-down menus: File, Edit, View, and Add. Some of the hot keys are function keys, some are single letters, and some require the Ctrl key. Note that they are case sensitive. You cannot customize them.

Toolbar Buttons

The main ViewDraw window contains four active toolbars. Hold your cursor over the buttons to see their function. A pull-down menu equivalent exists for every button.

You can dock these toolbars to the edges of the main window, or you can pull them off and leave them floating as shown in the “Toolbar” figure, “View Toolbar” figure, “Object Toolbar” figure, and “Transform Toolbar” figure.

Command Line

You can enter certain commands via the command line, shown in the “Command Line Toolbar” figure. You open this toolbar from View Command Line. You can dock or float it like the other toolbars. To obtain the complete list of valid command line commands, select Help ViewDraw Help Topics. Under the Index tab, select “Command Line Commands” and click on the Display button.

Right Mouse Click

Single-clicking the right mouse button brings up a list of context-sensitive commands that vary according to the cursor location.

Project Settings

The Project Settings dialog box contains a number of useful tabs for modifying your working environment. You can find some of the more common ones under the following tabs.

• Project
  
  Use this to set the number of levels of Undo. The default is 4, but you can set a higher number.
  
  
• Text
  
  Set the default text size here.
  
  
• Color Palette
  
  Set color templates here. The recommended Color Scheme is Classic Black.
  
  
• Object Properties
  
  

Use this tab to modify the colors and styles of nets, components, attributes, and the like.

Manipulating the Screen

Under the View pulldown menu, a series of commands allow you to modify the viewing area of the ViewDraw window. You can access most of these commands with the Function keys.

Selection Filter

Open the Selection Filter by selecting View Selection Filter. See the “Selection Filter” figure. This tool allows you to select only the specified types of elements in your schematic. For example, if you want to select only labels, click on All (to empty all the checkboxes), then click on the Label checkbox. Then, in your schematic, click and drag the left mouse button to select a region. Only the Labels in this region are selected.

NOTE

The Selection Filter still works even if it is closed; check the “All” checkbox before closing. If you find, while working on a schematic, that you cannot select certain items, open the Selection Filter and select “All.”
