BIMCamel
BIMCamel is a free set of online BIM tools that run in your browser. Open an IFC model, validate it against IDS, run clash detection, clean it, merge or split it, and convert it to glTF, Excel, DXF or COBie. A Navisworks plugin converts NWD and NWC files to IFC. 58 tools, no installation, no licence seat. A sample building is loaded, so you can see any tool work before uploading your own. Guests get 3 runs a day at 50 MB, and every tool is free on every tier.
