How to remove material from a 3D model

invincible

I have an extruded solid and I want to remove material to a partial depth, how to do that? I extruded the material inside again to a 2" depth (total depth is 2.5") and I tried to use the subtract command, but I am unable to remove it.

Hello.

The standard approach is to use the SUBTRACT command.
This works only with 3D solids.

Something to note here is the DELETETOOL system variable.
When DELETETOOL=0, the solids used to make the cut (the tools) are kept in the drawing.

If the workflow is to use EXTRUDE only, then you could check the system variable EXTRUDEINSIDE and set it to 1.
Then, extrude the profiles to cut from the main solid.
