Delete/Extract Faces

The Delete/Extract Faces function allows you to delete or extract one or more faces from solids and/or from sheet bodies. The sheet body must have more than one face.

Notes:

This function may be used to clean up a model, to remove features, to create a simplified model which can be used as a stock model after having run an Offset command, etc.
When a face is deleted/extracted, a new face can be created to replace the removed one.

Access

Click the icon in the Solids section of the ribbon in the Designer tab of the application.
Activate the Modelling tab and then click the icon in the Edit surfaces section of the ribbon.
This option may also be available in the context menu accessed by a Right Mouse click and in the Quick Access toolbar.

In all cases, this opens the Delete/Extract Faces - Options tab which is displayed along with the ribbon containing the Attributes, Selection, Filters, and Options sections.

Procedure

Using the Face selection filters, select the face(s) which you want to delete or extract.
Right Mouse click to confirm and to display the Options - Delete/Extract Faces dialog box. See dialog box.
