What you can do with it

Everything below is in the program today.

Sketch with real constraints

Lines, arcs, circles, splines and text, held in place with relations and dimensions that stay right when you change a number.

Turn sketches into solids

Extrude, revolve, sweep, loft, rib, shell, fillet, chamfer, draft, threads and knurling, with a feature tree you can edit and roll back.

Ready-made parts

Gears, pulleys and sprockets, springs, hinges, bolts and nuts, thumb screws, containers, end caps, and electronics enclosures with openings for ports and vents.

Made for printing

Print Check finds overhangs and thin walls. Fit settings adjust holes and outer sizes for your printer. Split big parts to fit the bed.

Photos to 3D

Turn a photo into a relief plaque or a lithophane, or build a 3D shape from one or several pictures.

QR plaques and signs

Make QR code plaques and stands with text and symbols, and test that they still scan.

Works with your other files

Open and save STL, 3MF and STEP. Open 3D scans (PLY and OBJ) and clean them up. Send a part straight to your slicer.

Assemblies and drawings

Put parts together with mates, check how they fit, and make 2D drawings with dimensions and a parts list.
