Midsurfaces Examples

Selecting an additional face pair with the Use selected faces option and the Selected Faces tool guide. All face pairs with the same offset are added to the selection.
Removing a face that was automatically detected but not desired as a midsurface pair.
Extend Surfaces is ON by default. Because it is obvious in the above example, the surfaces meet even when Extend Surfaces is turned OFF.
When the edges are rounded, the surfaces meet with Extend Surfaces turned ON. They do not meet with Extend Surfaces turned OFF.
Trim Surfaces trims the surfaces to the extent of the original body. In the example above, the slope at the bottom shows two different results. In the second image with Trim Surfaces turned OFF, the midsurface will extend to the extent of the largest face of the pair. In the third image with Trim Surfaces turned ON, the midsurface is trimmed to the sloped face.
