Create Face Pair
When you choose the Create Face Pair Features option, the system prompts you to select two or more side faces from opposing faces on the target solid. (The side faces are used in trimming and connecting adjacent face pair features.)
After you have specified the side faces, you can now create the midsurface feature. There are three suboptions (midsurface feature selection types) to choose from to create a midsurface.
