v0.7.1 — Large STL files open in a blink
✨ New features
Large STL files open in a blink
- Opening big STL meshes (tens of MB, millions of triangles) is now near-instant instead of a multi-minute wait. A 75 MB / 1.5-million-triangle STL that used to take ages now shows in under a second.
- STL is now parsed directly instead of going through the CAD kernel's importer, which used to build a full B-rep face per triangle (100k triangles: ~41 s → ~11 ms). Both binary and ASCII STL are detected and read automatically.
Customizable menu bar & quick toolbar
- A full menu bar groups every feature into categorized dropdowns, and a quick toolbar lets you tick just the buttons you use most — your selection is remembered between sessions.
About dialog with a changelog
- Help → About now shows a per-version, plain-language changelog so you can see what each release brought.
🐛 Bug fixes
STL geometry no longer leaks into STEP export
- STL is pure mesh (no B-rep), so STL parts are now correctly excluded from STEP export — earlier versions wrongly mixed STL shells into the exported STEP. Rigid transforms and measurement on STL parts are unaffected.
