You can replace the one body with an another body that underwent
Boolean operations.
This task shows you how to replace a trimmed
body with a basic body. As this basic body is not trimmed,
during the operation you will have to redefine the Union
Trim operation.
Replacing bodies cannot be used for previous
Boolean operations.
They can belong to the Part under study
or to an external part.
A Replace Viewer windows displays to help
you select the replacing face. Select Face/Pad.3/Body.4 as
the replacing face, directly from the geometry. Once the replacing face
has been selected, a green arrow appears on it.
Click OK to confirm and close the dialog
box.
Body.3 has been replaced with Body.4.
