You can select and then disconnect faces from a polygon mesh using the Mesh > Extract feature. Extract removes the polygons by duplicating the appropriate edges and vertices based on the selection.
You can either place the extracted faces into a new shell within the same mesh object, or create a new polygon mesh using
the extracted faces.
To extract faces from a mesh
- Select the faces you want to extract and choose Mesh > Extract > .
- Set the options as follows:
- If you want the extracted faces to become their own mesh, turn on . The extracted faces will be separated into their own separate object. Any pre-existing shells in the mesh will not be affected.
- Turn off to make the duplicated faces part of the existing mesh.
- If you know the exact transformation values you want to use, you can enter them in the option box, otherwise you can specify
them interactively later.
- Click .
The action creates a node and switches to the .
- Do any of the following:
- Use the manipulator to control the direction and distance to move the extracted faces. Remember that you can also change the
pivot by pressing Insert or Home. Click the circle handle attached to the manipulator to switch between local and world axes.
Note
The only appears when is on.
- Use the controls in the attribute editor or channel box to edit the extraction.
Keeping extracted faces together
The Keep Faces Together option (Edit Mesh > Keep Faces Together) controls how treats the edges of adjacent faces. When is on, the faces expand so their edges stay connected. When is off, the edges are disconnected.
Note
When the option is off and setting is on, each face becomes a separate mesh.
