Wall thickness in 3D models often appears messy due to inconsistent extrusion, non-manifold geometry, or improper boolean operations during creation.
- **Inconsistent extrusion**: Unevenly stretching a face to add thickness leads to irregular, uneven walls. - **Non-manifold geometry**: Open edges or overlapping surfaces break the model’s uniform structure. - **Poor boolean work**: Leftover geometry from cuts/joins creates messy, uneven thickness.
To fix it, use your software’s “check geometry” tool to spot errors. Then re-extrude with consistent settings or clean up boolean results to restore smooth, uniform wall thickness.
