SLSLICE — Slice a solid with a planeSee it in the command dictionary →

📝 How to do it yourself

Type SL and press Enter.
Select the solid.
Define the cutting plane by picking three points or an existing face.
Choose which side to keep, or type B to keep both.

ℹ️ What SLICE actually does

Cuts a solid with a plane and keeps one or both halves.

When to use it

Use it to cut a model at a floor level, produce a section, or trim a solid against a reference plane.

⚠️ Common mistakes

Picking three points that are nearly collinear, which gives an unreliable plane.
Forgetting to check which side you kept until after the command finishes.
