Potential Error Messages
- Unable to create this feature because it would result in zero-thickness geometry
- The model could not be properly sectioned by the section line. Please check that the section line cuts through the model.
Potential Reasons for These Error Messages
Zero-thickness geometry (also known as non-manifold geometry) exists when edges or vertices in a solid model do not properly connect with adjacent geometry. Every edge of a solid body must have exactly two adjacent faces. SolidWorks does not allow zero thickness geometry because it can lead to mathematical problems and downstream errors in the model.

Zero thickness occurs when you attempt to extrude a cut tangent to a hole.
This is frequently the cause of failed section views in drawings.

Potential Fixes
- Add or remove enough solid material to the area of the zero thickness geometry to properly connect the edges and vertices.
- In the Extrude PropertyManager, clear Merge result in Direction. This creates a multibody part.
