My builds are based on the current 0.6.0-rc version of the IfcOpenshell opensource framework. Despite the IfcOpenshell codebase being mostly blender ( blenderbim ) and python focused, it provides importer code for 3ds Max on the github repo. So i fought a whole afternoon with the somewhat convoluted build pipeline, and finally was able to build the plugins for 3ds Max .. hurray !
With the official release of 3ds Max 2023, i updated the zip to include the 3ds Max 2023 build too – link stays the same !
PS: i tested the plugins and was able to import some >100MB sample files. best thing is that the format tends to keep clean polygons/meshes, so no more tesselation hell, which is good !
Here’s a viewport snaphot of a free IFC sample ( > 100MB ) imported
