Constrained sketches
Lines, arcs, circles, slots and splines with coincident, tangent, parallel or symmetric constraints and dimensions that drive the shape.
AIM Solids
Parametric 3D parts, in your browser.
Draw a sketch, pin it down with constraints and dimensions, extrude it and round its edges. Change a dimension and the whole part rebuilds. When it's ready, export it to STEP for the workshop or to STL and 3MF to print it.
Free, no sign-up, no card.
For product designers, engineers, makers and 3D printing, and teams preparing packaging, brackets or custom parts.
What usually gets in the way
Pricey subscriptions for occasional use
AIM Solids is free and complete, with no time limit and no card.
Heavy software to install
AIM Solids opens in a browser tab: nothing to download, install or update.
Files only one program can open
AIM Solids opens STEP, STL and 3MF directly, with nothing to convert first.
What you can do with AIM Solids
From sketch to solid
Extrude, revolve, sweep or loft profiles into solids, and add or remove material in a single feature.
Part finishing
Fillets, chamfers, shells, threaded holes, draft angles, ribs and linear or circular patterns.
A timeline that remembers everything
Every feature stays in the history: step back, change a dimension or a parameter and the whole part rebuilds.
Assemblies and sheet metal
Place components with joints, check for interference and design sheet metal parts with their bends.
Measure before you make it
Distances, angles, areas, volume and the mass of the chosen material, without leaving the model.
Deliver in the format they ask for
STEP for machining and other CAD programs, STL and 3MF for 3D printing and OBJ for presentations.
With the rest of the suite

Questions about AIM Solids
Which formats does it open and export?
It opens STEP, STL, OBJ and 3MF. It exports to STEP, STL, 3MF and OBJ, as well as its own format, which keeps the part's whole history.
Can I change a dimension later?
Yes. Dimensions and parameters stay live: change them and the part rebuilds with all its features.
Are my parts uploaded anywhere?
No. AIM Solids works inside your browser, with the files on your computer.
