Setting vertices as free vertices prevents them from being affected by Attract and Stick operations; that is, they will not be wrapped around the target surface.

This feature is very useful when the target mesh is missing or the data in certain areas is inaccurate. You can avoid being wrapped around these areas.

To do this, click the Free button to display free vertices, then switch to Blender's edit mode, select the vertices you want to set as free vertices, and then click Add.

Setting vertices to fixed vertices allows them to remain stationary during the wrapping operation.

When you need to wrap around a portion of an object, it’s very useful to maintain consistency by setting the vertices on the boundary as fixed vertices.

To do this, click the “Fixed” button to display the fixed vertices, then switch to Blender's Edit Mode, select the vertices you want to set as fixed, and finally click Add.
