OpenSCAD From Profile to Solid example
Foundations
Lesson 4 of 22
Reuse a 2D module inside linear_extrude to make a slotted solid.
Try changing:

How this model works
The profile module remains entirely 2D. Wrapping it in linear_extrude produces a 3D part whose holes pass all the way through. Modeling complex constant-height outlines in 2D first is often cheaper than many 3D boolean operations.

Make it your own
Temporarily replace linear_extrude(height = thickness) profile(); with profile(); and switch to 2D/SVG. Restore extrusion and check that XY dimensions stay unchanged.
Change one parameter at a time and inspect the result. Use the workspace reset action to return to this lesson’s original model.
