From the Operation section of the action bar, click Cutout.
In the Feature box, select
a wall, ceiling, or covering.
Under Cutout Definition, select a cutting element under the
Cutting Element column.
Notes:
You can select a closed output profile, closed surface, or volume.
The cutting element must fully intersect with the feature. In case of an output
profile, the profile is projected on the feature.
A name is automatically assigned to the cutout feature under the
Name column. You can change it as required.
A new row is added for another cutout creation. In this way, you can create several
cutouts on the selected feature by selecting several cutting elements.
