Remove Surface Fillets
Use the Defeature: Fillets tool to find and remove both round (convex) and fillet (concave) surfaces.
The Defeature: Fillets tool allows you to select a round or fillet, and find all that are larger, smaller, or similar (±5%) in size. In general, it is best to remove small fillets first, then larger fillets, then rounds. When you get to a point where you cannot remove any more, it is time to use other modeling tools and strategies to complete the geometry simplification.
Note: FE geometry is not supported for this
tool.
-
From the Geometry ribbon, click the tool.
Figure 1.
- Optional:
On the guide bar, click
to define settings used to
find and select rounds/fillets of a specific size.
-
Review each selected round/fillet by clicking
and 
on the guide bar.
Tip: You can also select surfaces manually without using automatic detection. If you have already used the Features tool to detect fillets, you can change the entity selector on the guide bar and select them directly as well. - Optional:
Select lines that a fillet should ignore.

- Optional:
Select lines which make up the end of a fillet.
