Point at what you mean

Click a face, an edge or a whole part and it becomes a reference in your message. Hover a reference to see exactly what it points to.

Keep the opening centered on LCD · display face and move switch_2 2 mm toward +X, clear of lid · opening edge.

Design around the parts you already have

Attach STEP files for your board, display and switches. They stay exactly as imported and locked in place while Extrastep builds the enclosure around them.

Every turn is a revision

Your design is parametric source, rebuilt and checked after every change. Revert to any turn, fork a variant, and export the revision you want.

Checked before you see it

Each change is measured against your request, then reviewed from fresh isometric and orthographic views before it is published.

Ø3.2 THRU ×4

Exact geometry, not a mesh

Results are solids built from parametric source, so a 3.2 mm hole is still a 3.2 mm hole in the STEP file you export.

Your view stays yours

Orbit, section and hide parts while the agent works. When the result arrives, the camera stays where you left it.

Start with the parts you have.
