Create and edit a 2D sketch curve, and then extrude it to create 3D solid geometry. A sketch curve is any "wire" entity
such as a line, rectangle, circle, or arc.
Use the Patch, Push/Pull, Partition, and other core geometry tools to modify surfaces
and solids.
Patch
Use the Patch tool to fill in missing surfaces, or to remove and remake bad or problematic surfaces.
Push/Pull Faces
Push and pull a face, line, or 2D edge to extrude it into a solid or surface, create or resize a hole, eliminate rounds, or modify wall thickness.
