About Remove Face Features

Topology

Remove Face does not create any new face. The capability is valid for existing topology extrapolation. This is why the following pink face cannot be removed:

However, this one can be removed because there is a possible trimming face that can be used by the app.

Self-Intersecting Volumes

The Remove Face capability may produce self-intersecting volumes as illustrated in the following example:

Initial Geometry

The 3D shape is composed of a shelled pad. Two fillets (in lavender) were created on two of its edges.

Resulting remove face feature

Removing the internal fillet feature generates an inconsistent shape.

Tip: To analyze self-intersecting volumes, we recommend you use the Split capability which most of the time provides a better view of the problems:

Removing the appropriate face

By removing the external fillet first there is no self-intersecting volumes, the resulting geometry is satisfactory.
