About Materializr

Materializr is open-source 3D CAD for makers - the middle ground between dead-simple tools like Tinkercad and full professional suites like FreeCAD. Enough genuine solid modeling to make real parts, without a steep learning curve, a subscription, or an account.

Sketch on a plane, pull it into a solid (extrude, revolve, loft, sweep), fillet and chamfer, run boolean operations, cut threads, and edit any step of the history later - even after closing and reopening the project.

Sketches export to SVG at 1:1 millimeters for laser cutters and 2.5D CNC. It also imports STEP and IGES, and exports STEP, STL, IGES and glTF.

The geometry kernel is OpenCASCADE - real B-rep solids, not meshes. The interface is touch-capable on Android, designed for tablets and larger screens (on a small phone the panels and toolbars are cramped). File open/save use the system document picker (Storage Access Framework); no broad storage permission is requested.

Young software built quickly, so expect rough edges. Operations validate their results and refuse rather than silently produce garbage, so a failed action leaves your model untouched - but save often, and please report bugs.

Release notes Materializr 1.7.7

A first pass at sketch construction geometry, a whole-interface scale slider,
more control over the sketch grid, and a round of fixes from tester reports.

Added
o Construction geometry (early version). A Construction button in the
sketch tools. With lines, circles, arcs or splines selected it turns them into
construction (or back); otherwise it makes what you draw next construction.
Construction geometry draws dashed and teal, stays selectable and snappable,
and has no effect on the shape: regions, extrudes, push/pull and SVG/DXF
export come out exactly as if it were not there. Trim, mirror, copy and
patterns keep the flag. This is only the first part of the feature: infinite
lines, horizontal/vertical/parallel helpers and tangents are not here yet, and
feedback on what it needs next is very welcome.
o Interface scale slider (Settings ? Appearance, 75% to 250%) on desktop.
Scales the whole interface together (text, buttons, spacing, panels) on top
of the size picked for your display, for when everything is too small to read
without switching to Touch mode. Takes effect on restart; use Reset panel
layout afterwards if the panels look cramped.
o Scale grid with zoom switch and a Step switch size slider in the snap
popup under the ViewCube. The switch turns the zoom-scaled grid on or off; the
slider (4 to 40 px) sets how wide a grid cell may get before the step changes,
which helps on screens where the cells look too fine or too coarse.
o Grid rendering (experimental) in Settings ? Rendering: three workarounds
for a grid that shimmers or flickers with anti-aliasing on certain GPU drivers
(seen on Intel Arc). Leave it on Default unless the grid looks wrong.
o Android: Full screen switch (Settings ? Appearance). Off by default, which
keeps the status bar visible; on hides it as well.

Changed
o Rectangle and Circle choose their origin from a menu. Click the tool again
while it is active to pick Corner or Center (Center or 2-Point for circles).
