Sketching toolset allows you to draw 2d profiles, which can be extruded or revolved to create 3d solids and surfaces or to add/subtract volume to/from existing entities. Tools to work with sketches are available on the Sketch tab of the Mechanical workspace Ribbon:
Sketches are drawn in XY plane of the User Coordinate System (UCS). By default, the dynamic UCS is enabled, which allows you to draw directly on faces your 2d solids and surfaces. You can also use Align UCS tool to position UCS as you need.
You can make your sketch parametric using 2d constraints.
|NOTE||By default, sketching entities are deleted after they were extruded/revolved to create 3d solids/surfaces. To avoid that, set DELOBJ (Delete Entity) system variable to 0 (never delete) or -1 (prompt before deletion).|
