# 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.
