### 5/5 — Great stuff

*2026-08-09*

Initial impressions are fantastic. 

Two small pieces of feedback: there have been a couple .3MF that have been unable to render (but have also printed successfully). And a feature request to be able to view flat 3D files like DWG.

**Developer response:** Thanks for the 5 stars!
For the .3MF files that fail — mind mailing one to support@open3d.app? I'll trace exactly why and patch it.
DWG is closed-format so it needs a bit of plumbing, but I'm adding auto-DWG support in the next Windows update (v1.1.4) via ODA File Converter. Coming soon.

### 5/5 — Looks good

*2026-07-11*

Just getting started but looking good so far!

**Developer response:** Thank you !
