A solid is a surface or polysurface that encloses a volume. Solids can be edited without breaking them into individual surfaces. These commands do their best to maintain the closed solid.
Fill planar openings with a surface joined to the hole edge.
Create a ruled surface at polysurface edges.
Create a closed polysurface from surfaces.
Create a tangent surface between polysurface edges.
Rotate polysurface faces around an axis.
Combine co-planar polysurface faces.
Combine all co-planar polysurface faces.
Move a polysurface edge.
Move a polysurface face.
Move the edge of an untrimmed polysurface face.
Move an untrimmed polysurface face.
Remove the selected surfaces from a polysurface, and then offset the remaining surfaces to create a solid with a specified thickness.
