Point cloud comparison on ifc model?
I want to compare two ifc models one drawn using point cloud by visual interpretation and left one ifc model drawn with construction drawings
- I want to mark elements changes, missing, in terms of size and location

Hello ! I don't know about Blender specifically but CloudCompare (FOSS) has features for cloud to mesh distance https://www.cloudcompare.org/doc/wiki/index.php/Cloud-to-Mesh_Distance
In Blender one could try a solution with Geometry Nodes and a proximity based workflow (eg isolate points that are < 5 mm for a mesh object or conversely) but I would reduce significantly the density of your point cloud beforehand unless you have a powerhouse of a PC.
Thank you @Gorgious
