Repairing and Defeaturing
When importing 3D CAD files, the default import settings ensure that the validity of the imported objects is checked, and that defects are repaired when possible. In addition to the checks and repair performed during import,
the CAD Import Module provides operations for checking, repairing, and defeaturing 3D geometry objects, and locating overlaps and gaps in imported CAD assemblies.
Operations for Checking and Repairing 3D Objects
Use the operations listed in the table below to check and repair geometry objects and to detect interferences between objects:
Table 2-3:
Operations for Detecting defects in and Repairing 3D objects and detecting interferences between 3D Geometry objects.
Icon
Name
Description
Check
Check CAD objects for faults, for example tolerance issues and invalid entities
Detect Interferences
Search for interferences, such as intersections, gaps, touches, and containments, between objects
Repair
Repair defects and remove small details from 3D objects
Operations for Defeaturing
With the defeaturing tools listed in the table below you can search for and delete both small details, such as short edges, small faces, sliver faces, and spikes, and larger details, for example, fillets, chamfers, and cylindrical holes. You can also replace and detach a selection of faces to form 3D objects.
