there are 13 elements that, with their multiple copies, have more geometry than the actual first and second floor model.
Now I’ve never used Revit, but I’ve used and imported lots of files from lots of softwares.
If you have a hand on the revit file, and you need to export / import things quickly (quicker), you could export your revit file in several ifc (if revit allows it)
Say, you export one ifc with the building itself, one with the furnitures and lights of the ground floor, another with the first floor. By making smaller more manageable ifc files it could mean a faster non crashy import in sketchup, and all you would have to do is just stack them.
You can test with Trimble Connect too. If you export to trimbim you obtain a similar model than yours with pCon. That was the reason why I asked about information…
I haven’t checked the ifc file, but in the rurals of the ever evolving methods and ways of exporting ifc (eg. the export settings in the software) an older exported file is different than an export from a neeer version.
It is all about mapping psets or software properties to ifc parameters.
Those can be investigated with an add on like arilius Attribute inspector for those who are interested, but generally, the SketchUp model would be used as a start for creating nice renderings.
If it would be used to collaborate, a strict method or IDS (information description standard) must be used upfront the export and later on import.
Designers and architects have less interest in that than engineers IMO and experience.
Nevertheless I would like to have a native way to see those properties, though.
The real focus of BIM I think is the description of what is (going to be) build, or Object. How that is represented through the different kind of software is of less importance.
Since SketchUp is just plain edges and faces, we need a solid way to describe and add properties to the objects.
Quadri (Trimble civil software) does just that, it converts any input (Tekla, Revit, SketchUp, GIS, dwg) into ‘features’ that can be mapped (automatically) to the right ‘category ‘ resulting in a very constant IFC output.
The better option for importing ifc´s is still to not import ifc´s, but put the file in the cloud in Trimble Connect, convert it to .trb, download it, and import that download.
You then get tags intact, and a much smaller file. Components/instances are still broken, so SU is still taking some Information out of the Building Information Modelling (BIM) files
