To Invert a Part

The Invert command flips the orientation of all triangles of the part. Parts with a valid orientation become inverted and get a negative volume. Invalid parts are made valid. The shape of the part remains unchanged during this process. To invert a part:

  1. Select the part.
  2. Click Modify > Invert.
  3. Click Yes to replace the current part with the inverted part or click No to create a new part.
