Repair Surfaces
Use the Surface Repair tools to find, review, and fix any geometric errors in the model's surfaces.
Closed Shells
Shows the surfaces which are closed but do not form solids. You can construct solids out of these surfaces.
Toggle options for detecting baffles and considering solid surfaces.
Free Edges
Shows free edges in the displayed surfaces.
- If the free edges form a loop, use the Patch Hole option to fix them.
- If two edges are close by, the Stitch or Stitch and Intersect
option to connect them within a given tolerance.
You also have the option to only stitch open loops.
- If surface are floating, use the Delete option to remove those surfaces.
Non-Manifold Edges
Shows non-manifold edges (edges where more than two surfaces are connected) in the displayed surfaces. You can fix them in this tool by deleting the surfaces attached to non-manifold edges.
- Edges attached to baffles and interface surfaces are not considered here.
- If you do not want to delete the surfaces, you can isolate them and fix them using the Stitch Surfaces tool in the Edit tool group by collapsing points of non-manifold edges.
Self Intersections
Shows surfaces which have intersections within the surface or belong to one solid. You can fix them in this tool by:
- Optimizing CAD with or without re-faceting
- Performing batch repair
- Splitting surfaces
- Deleting surfaces. Afterwards, you are left with free edges, which you can repair using the Free edges check.
For complicated models, removing self-intersections and recreating the surfaces is not easy. With these new features, you can clean up using geometric or fix tolerance and ease the cleaning process.
Sliver Surfaces
Shows surfaces which have regions that are narrower than a defined threshold.
To define the threshold value, click on the guide bar. The default tolerance is based on the geometric tolerance defined in the Preferences dialog. You can reduce the value in this tool if you wish to retain some valid sliver surfaces.
You can fix slivers by collapsing the edges or suppressing the edges. If Suppress Only is turned on, it will provide you the option to suppress individual edges of sliver surfaces. Upon submitting, it will suppress all sliver surface edges which are below a 60 degree angle. The rest of the edges you need to manually suppress.
For CAD geometry, you can also perform batch repair to auto-suppress edges based on given tolerance.
Duplicates
Duplicate surfaces overlapping each other and connected with green edges can be deleted.
