Extrude
Key E; straight to a cut — Q.

Select one or more sketch outlines, set the operation and the height above, press Enter.
The operation matters more than it looks
- Add — material appears.
- Cut — material is removed.
- Intersect — only the common part stays.
This is one command with three modes, not three different tools. That is why “Extrude” and “Cut” are a single button: they share the fields, the preview and the timeline node.
Several outlines — one node
Select three outlines and you get one feature with three profiles, not three features. That matters: editing reopens all three at once, and deleting removes the whole operation without breaking the part.
Nested outlines (an outline inside an outline) are handled by themselves: the inner one becomes a hole.
Direction and depth
The height is a number or a formula. A negative height extrudes the other way.
