Extruding (by Olivier)
Dear SolveSpace aficionados, I was wondering if you could advise me on this situation:

I drew a sketch which represents a plate cut-out within the model I am working on. This is on group 002.

I then drew a rectangle to represent the plate; this is on group 003. (This is on the same plane)

I extruded the rectangle to form the plate; this is on group 004.

Ideally I would like to then cut-out the group 002 from this extrusion, but I can't seem to figure out how to do this.

If I choose Extrude with group 004 active, it doesn't use group 002 as the base for extrusion.

If I choose Extrude with group 002 active (and put it into Difference mode), it does extrude using group 002 as the base, but the extruded group (group 005) is placed BEFORE group 003 so it doesn't affect the later group 003/004.

i.e. the group order becomes
g001-#reference
g002-sketch-in-plane
g005-extrude
g003-sketch-in-3d
g004-extrude

How can I reorder these or somehow make the correct extrusion?

Many thanks for your time.

Could you give your file and/or image for needed model?

Operation order (by Andrew)
The correct order is to draw, extrude lathe etc as the next operation, and the draw, extrude etc.
That is you should have
g001-#reference
g002-sketch-in-plane
g003-extrude
g004-sketch-in-3d
g005-extrude

Mistake is that you try extrude "sketch-in-3d" group - its impossible in SolveSpace! (as I know, but maybe I'm wrong...)

You must create additional "sketch-in-plane" using some entities from "sketch-in3d". So, your model must look like this:

g001-#reference
g002-sketch-in-plane
g003-extrude
g004-sketch-in-3d
g005-sketch-in-plane
g006-extrude
