Use the PushPull command to extrude 2D entities into surfaces and to modify 3D solids.
The results vary based on the type of entity. If you push and pull linear entities such as lines or arcs, you create surfaces. For 3D solids, if you push and pull existing closed entities such as Circles and PolyLines, you modify the geometry of the 3D solid.
For 3D solids, you can simultaneously modify multiple closed entities.
To modify 3D solids by pushing and pulling geometry:
If you want to extrude more than one entity, specify the Multiple option.
You can click inside an entity (3D solid or area) or a face of a 3D solid and then drag it in or out. Thus you can create a hole or an extrusion.
Note: You can specify multiple faces of the same 3D solid. The command will extrude all specified faces at once.
The shape of the selected entities is extruded with the specified height.
