### Detecting Collisions

The Operation | Graphics Display Window | Collision Detection menu option (CD) displays the Collision Detection dialog box. The CD module is designed to detect collisions between the probe and CAD surfaces. All CAD curves, lines, and points are ignored. As a result, only CAD files that fully describe the part using surfaces are suitable for collision detection. (The CD algorithm doesn't use the actual surface definitions, but rather the surface tessellations (or graphical approximations), which are also used for rendering solid views using the OpenGL graphics language.)

Changing Animation Speeds: If you want to modify your offline animation speeds, see the "Execution area" in the General tab of the SetUp Options dialog box. In addition, see "Executing and Debugging Part Programs Off-Line" in "Working in Off-line Mode".

Viewing Collisions for a Range of Selected Items

You can also limit the collision detection items by selecting a range of one or more features in the Edit window and perform the collision detection on only those selected features.

To do this:

1. In the Edit window select the range of features. Either click and drag the selection (if in Command Mode) or click on the first feature, press SHIFT and then click on the second feature to establish the range of features (if using Summary mode, you may also press CTRL instead of SHIFT).

2. Right-click in the Edit window. A shortcut menu appears.

3. Choose Selected Items Collision Detection. PC-DMIS automatically performs the collision detection on those features, drawing path lines as the features are processed. A check box then appears next to the short cut menu item.

If you want to immediately select a different range of features. You need to right-click in the Edit window and clear the Selected Items Collision Detection first and then re-select it for the new selection.
