Invalid Entities

Invalid entities are faces or curves with geometrical problems that prevent most operations, such as Split or Trim, from working properly.

Recommendation

Try and fix all the invalid entities using the Fix invalid entities option in the Check & Fix Entities function.

Unsolved Cases

If the Check & Fix Entities function fails to fix a problematic entity and this entity is required for CAD operations (for example, Split or Trim), it is recommended to remove the original entity and recreate it manually.
