Open the Quad Draw tool marking menu by Ctrl + Shift + right-clicking anywhere in the scene when the Quad Draw tool is active.
- Auto-weld
-
Adjust the slider to set the tolerance of the weld operation. For example, if the Auto-weld tolerance is set to 10, any components that are 10 pixels or less apart are merged.
Note: Auto-weld has no effect when Soft Selection is enabled. - Extend: Edge
-
Extends a single edge of a mesh.
Tip: When Extend: Edge is selected, you can also drag vertices to create new polygons. - Extend: Loop
-
Extends an edge loop of a mesh.
- Extend: Border
-
Extends the border of a mesh.
- Relax: All vertices
- The relax brush affects all vertices.
- Relax: Border vertices
- Locks interior vertices so they remain in the same position while you relax border vertices.
Note: You can relax borders when Relax: Border vertices or Relax: All vertices is enabled, but Relax: Border vertices produces a slightly different result, because it only averages the weights of border vertices.
- Relax: Interior vertices
- Locks border vertices so they remain in the same position while you relax interior vertices.
- Relax: Auto-lock
- (Default) Uses the location of the cursor to determine which vertices (interior vertices or border vertices) to lock. When you start to relax border vertices, the relax brush automatically pins interior vertices. When you start to relax interior vertices, the relax brush automatically pins border vertices.
