Patch
Use the Patch tool to fill in missing surfaces, or to remove and remake bad or problematic surfaces.
Location: Geometry ribbon, Create group

If the Patch tool finds a group of open edges that define a closed loop, clicking a red edge will close the hole.

Figure 1. Patched Surface
If you select two groups of edges or lines that do not define a closed area, the Patch tool will create a surface between the groups.

Patch Missing Surfaces
Patch open areas that define a closed loop, or create a bridge between two open edges that do not define a closed area.
- To review open edges located by the search, click
and
on the guide bar.
- To change the continuity of the patch where it meets an adjacent surface, click the edge. The continuity will toggle between linear and tangent with successive clicks.
- Some geometry tools automatically detect relevant features when the tool is opened. You can disable this behavior in the Preferences under .
Remove Problem Surfaces
Click once to select a problematic surface, and again to remove it.
- Click the Patch tool.
- Click a surface to select it. The surface turns red.
- Click the surface again to remove it.
