Hi Everyone,

I have been looking in the forum but could not find loads of info on 3d Clash detection, a topic I thought would be quite common here. Nonetheless, I have made an example script trying to catch Objects in an .ifc Model which are Geometrically modelled over one another. This is quite easy to test and visualise in Navisworks Manage or DeSite - IfcViewer Softwares.

In FME Desktop I attempted using the Matcher, Geometry Validator and CRC Calculatoras with a 2d SurfaceFootPrintReplacer, but to no avail. The clashes are not shown in my workspace, where am I going wrong?

Thanks for any help or suggestions.

Fred
