Hi everyone, over the years this community has saved me countless hours — so I wanted to give something back.
During facade design work I kept hitting the same wall: comparing two revisions of a complex geometry assembly without going element by element. I never found a tool that just handled this cleanly, so I built one.
What it does: Overlays two versions of the same geometry and highlights every point that doesn’t match — each revision in a distinct color. Works directly on raw BREP and mesh data, no prior conversion needed regardless of source — Rhino, Revit, STEP, SketchUp, etc.
Output includes a structured list of detected differences with spatial location — hole diameters, shortened/extended parts, modified profiles, angle changes on roof sections and structural assemblies.

This is my first public release, so I’m honestly not sure everything runs as smoothly as it should across different setups. Please give it a try and let me know — what breaks, what’s missing, what behaves unexpectedly. Any feedback is genuinely useful at this stage. If there’s interest, I have more features ready to build on this.
