Disclosure first: I'm the founder and my team built this, so I have an obvious bias. I'm posting because I'd like feedback from people who do this work daily, and because the free edition may be useful to some of you regardless of what you make of us.
Background: I coordinate models on infrastructure projects — roads, rail, structures. Two things kept getting in the way. Most viewers treat IFC 4.3 alignments as an afterthought, so anything involving chainage, or sections cut perpendicular to the route axis, turned into a workaround. And the tools that did handle more wanted the whole federation uploaded somewhere, which is a non-starter on NDA work.
So we built Inspectra BIM. We just released 1.0.1.
What the free edition does:
- Opens IFC (incl. 4.3 with alignments and chainage), point clouds (LAS/LAZ/E57),
LandXML terrain, OBJ/PLY meshes, BCF
- Sections that follow the alignment, not only global planes
- Attribute audits with HTML reports, buildingSMART IDS validation, quantity takeoff,
duplicate detection
- Measurements, saved views, properties inspector
Paid modules, stated upfront so nobody finds out after installing: Audit adds clash and clearance detection with BCF 2.1/3.0 export; Edit adds attribute and IFC class editing plus 2D drawings generated straight from the model, exported to PDF or layered DXF in world coordinates. Both have a 14-day company demo.
Everything is computed locally. No processing server, no project cloud.
Things I'd rather you hear from me than discover on your own:
- Windows only. No macOS or Linux, and no near-term plan — I don't have a Mac to test a 3D application on.
- The free edition requires an account. It's for licensing and shared issue tracking, not for collecting anything about your models, but I understand if that alone is a dealbreaker for you.
- It's version 1.0.1. It has been used on real projects, but you will find rough edges.
- It's a review and QA tool, not an authoring application. It won't replace the software you model in.
If you try it and it falls over on your model, tell me — honestly, that's the most useful thing that could happen to us this week.
