Sometimes it is necessary to view where parts interfere with each other and where they touch. Creo Elements/Direct Modeling displays where parts interfere (clash) or touch in user-definable color:
• Red: Parts that interfere (volume2)
• Yellow: Parts that touch (area 1)
Visualizing parts that clash
The previous example shows parts p1 and p2 touching at point 1, and parts p1 and p3 interfering at point 2. The interference volume result can be saved as a separate part. The touching sheet part result can also be saved as a separate part.
In addition to the graphical representation, Creo Elements/Direct Modeling also displays an output window listing which parts clash or touch. This list gives all possible combinations of interfering or touching parts.
With Creo Elements/Direct Modeling's clearance functionality, it is also possible to determine the shortest distance between two parts.
After creating your assembly, you may want to know if any of the parts interfere or touch each other. Creo Elements/Direct Modeling lets you view volumes of interference and areas of touching with the Clash command. Interference volumes and touching areas can be saved and treated as a separate part in the assembly.
You can also use the Clearance command to determine the clearance between parts.
For Clash or Clearance command, click Analysis and then, in the Verify group, click the arrow next to Clash/Clearance.
For a much quicker (but less accurate) graphical indication of interference, you can also use clipping planes and the visual interference check available in the Vp menu. Use Clash to determine volumes of interference precisely.
Parts that touch at vertex points or along edges are not detected and are not highlighted. Wire parts and face parts cannot be viewed with the Clash command.
