Materializr 1.7.5

Sketching and laser work: fill regions for engraving, rebindable keyboard shortcuts, a Trim that cuts splines, and a round of fixes from tester reports.

Added

• Fill tool for laser engraving. In sketch mode, click or tap a closed region to fill it, and again to clear it. Fills are cosmetic: they never affect Extrude, Push/Pull or any other modeling. SVG export writes each fill as a path and DXF export puts it on a FILL layer. Exporting a sketch with fills asks whether to make them grey, so laser software can give them a different operation than the outlines.
• Rebindable keyboard shortcuts. Settings ▸ Navigation lists 18 shortcuts; click one and press the new combination. A combination already in use is taken from its old action. The menus, the Interactions panel and Help ▸ Keyboard Shortcuts show your bindings.
• Custom polygon sides. The Polygon tool has a "Custom..." entry for any side count from 3 to 128.
• Camera glide into a sketch. The view now eases into the sketch plane instead of jumping. Settings ▸ Navigation ▸ Animate camera moves turns it off.

Changed

• Trim cuts splines and polygon edges. Before, one click removed the whole spline or polygon. Now a spline is cut at its crossings and only the stretch under the cursor goes, and a polygon edge is trimmed like a line. Splines also act as cutters when trimming lines, arcs and circles, and the hover preview shows exactly what a click will remove.
• Seam lines on round faces are no longer drawn.
• Chamfer and Fillet: a rejected size keeps your selection and the panel open instead of dropping you out, and the size stepper gains -0.1, -1 and -10 buttons.
• The startup tab no longer carries a stray demo cube, so opening a project from the home screen doesn't leave an extra tab behind.

Fixed

• Push/Pull on a whole sketch no longer cuts or raises the entire face behind it.
• Deleting circles, arcs and splines from a sketch works, and deleting from a sketch now updates bodies built from it, including Lathe. Undo and redo follow too.
• Undo "stuck in a loop". Undoing a sketch edit could jump forward through steps you had just undone.
• Typed Extrude and Push/Pull distances are now exact. Pressing Enter with grid snap on rounded a typed 0.2 to the grid and committed nothing.
• Chamfer with a setback exactly equal to the neighbouring face no longer fails as invalid geometry.
• Scaling a body could close the app on the next autosave. Uniform scale is now exact, and a save error is reported instead of crashing.
• Edge selection works when you click just outside a silhouette edge, and thin faces keep a usable edge target.
• Selecting a circle by its rim with drawing aids off no longer misses.
• Translation gaps filled across the sketch toolbars and menus.
