Create a new solid or add to an existing solid by extruding (pulling) a 2D sketch, 3D face or face with tolerant edges in a given direction. (To remove solid material, see Extrude Remove.)
Important: Extrusions created by New > Extrude will be considered independent objects. Those created by Add > Extrude will be added to the active object. (If only one object exists in the file it is automatically active unless manually deactivated or if the active object is deleted.) See Activate / Deactivate and Activating Objects.
Creating an Extrude – Detailed Interaction of All Options
- Delta/Reference: Extrude either by Delta (extrude on one or both sides, by a given value and direction) by Reference (extrude to a reference face or plane).
- Delta Mid Plane: Extrude by the same amount equally in both directions.
- To Closest (Add Extrude only): Extrude to the closest faces of an active object, according to a defined direction.
The following is the Feature Guide for Add / New Extrude.
