To Set Collision Detection Settings
Collision detection settings can be set in Assembly and Mechanism Design.
1. Click > > 
Model Properties. The Model Properties dialog box opens.
Model Properties. The Model Properties dialog box opens.2. Click change in the Collision Detection line. The Collision Detection dialog box opens.
3. Set a General option during drag operations.
◦ No collision detection—Performs no collision detection and enables a smooth dragging even in case of collision.
◦ Global collision detection—Checks for any kind of collision in the entire assembly and indicates it according to the option chosen.
◦ Partial collision detection—Specifies the parts between which to check for collision. You are prompted you to select parts. Press and hold CTRL to select more than one part.
These settings are supported only for Drag and Playback operations and are not applied during Motion Analysis or Mechanism Analysis.
4. Select Include quilts to include surfaces as a part of the collision check when the highlight_interfering_volumes configuration option is set to Yes.
5. Select Optional settings to choose settings for each type of collision detection. These settings are only active for Partial collision detection or Global collision detection when the enable_advance_collision configuration option is set to yes.
◦ Stop when colliding—Stops movement if there is a collision.
◦ Highlight interfering volumes—Highlights the interfering entities. The default when the configuration option is set to no.
◦ Push objects upon collision—Shows the effect of the collision.
These settings are supported only for Drag and Playback operations and are not applied during Motion Analysis or Mechanism Analysis runs.
 | • In large assemblies with many rigid bodies, the advanced collision detection options can cause very slow movement of the assembly. • When you select Sound warning upon collision, a warning bell sounds upon collision. When you select Stop animation playback upon collision, playback stops upon collision. These options are available only when the enable_advance_collision configuration option is set to Yes. • The optional settings are not applied during analysis, however, the collision-related results are still generated as part of the analysis output. The Results table can report whether a collision was detected and which parts collided. In addition, interfering geometry can be visually highlighted as part of the analysis results, allowing you to see colliding volumes without enabling advanced collision options. |
