From first line to printed part.
Draw with inference, lock with constraints.
Lines, arcs, splines and polygons with SketchUp-style snapping — endpoints, midpoints, perpendicular, tangent, 15° increments. Add dimensions and constraints only when you want them.
Pull a sketch into a solid, then keep editing.
Push/pull, extrude, revolve, sweep, loft, booleans, fillet & chamfer, shell, mirror, patterns. Edit faces directly — taper a draft, scale a wing tip, dial a hole to an exact diameter.
Real threads. Logos wrapped around curves.
Validated internal and external screw threads with sensible coarse defaults. Projection engraves or embosses any sketch onto a flat — or curved — face. Wrap a logo around a cylinder in a few clicks.
Plays nicely with your whole pipeline.
STEP and IGES in and out, STL and glTF export (Z-up corrected for printing), SVG import, PNG viewport export. The native .materializr format stores bodies, sketches and the full editable history.
Every operation stays editable — forever.
Each action is a history step you can revisit, even after closing and reopening the project. Construction planes & axes, Section View, version snapshots with auto-save, and undo everywhere.
What it is
Enough genuine parametric solid modeling to make real parts — without a steep learning curve, a subscription, or an account. If beginner tools feel limiting and pro tools feel heavy, that gap is exactly what Materializr is for.
What it isn't
It isn't trying to replace SolidWorks, Fusion 360 or FreeCAD. It's young software built quickly, so expect rough edges — but operations validate their results and refuse rather than corrupt your model. Save often, and send bug reports.
