There are four default clash test types for you to choose from:
- Hard. Choose this option if you want the clash test to detect actual intersections between geometry.
- Hard (Conservative). This option performs the same clash test as Hard, however, it additionally applies a conservative intersection method.
- Clearance. Choose this option if you want the clash test to check for geometry within a specific distance from other geometry (see tolerance for more information). You can use this type of clash when, for example, pipes need to have space for insulation around them.
Note: Clearance clashes are not the same as “soft” clashes. Clearance clashes detect for static geometry coming within a distance of other geometry, whereas soft clashes detect potential clashes between moving components. Clash Detective supports soft clash checking when you link it to Object Animation.
- Duplicates. Choose this option if you want the clash test to detect for duplicate geometry. You can use this type of clash test to check a model against itself to ensure the same part has not been drawn, or referenced twice, for example.
