Controlling the Display

The display controls how three-dimensional objects are transformed to a two-dimensional screen. Two important features for controlling the screen are the view and zoom tools. A view describes the orientation of your eye position and direction towards the model. Example view operations include the side, front, top, and isometric options. Zooms describe a window looking into the model defining the scale and clip extents. Example zoom operations are pan, extents, and scale. This chapter introduces you to the following display functions:

  • Predefined Views
  • Zoom Options
  • View Tool Palette
  • Predefined View Short Cuts

Predefined Views

(ViaCAD Deluxe and ViaCAD Pro)

ViaCAD supports eight predefined views. You can change to a predefined view by accessing the View option from the Menu Bar on top of the screen.

Six of the predefined views locate a viewer such that they are looking parallel to the model axis. The other two views allow isometric viewing from the front and back of the model.

Predefined Mouse Operations

ViaCAD has four predefined view operations associated with the mouse buttons.

Mouse Button

View Operation

  • Space/Left Button
  • Pan Views
  • Wheel Button
  • Zoom In/Out at Cursor
  • Control/Apple Right Button
  • Rotate View via Cursor

Some of the new mice will allow you to assign keys to the mouse buttons and the scroll wheel. If you have a mouse that does this, you can assign a key (i.e. “z”) to the mouse button, then within ViaCAD assign the key (i.e. “z”) to one of the many viewing operations in the File: Short Cuts dialog box.
