At my firm, we are now needing to start integrating our models with our consultants and are needing to be exporting IFCs for use for them. We have previously exported IFCs on earlier jobs, but for some reason, when I am creating my IFC files (trying a couple different buildings), the exterior complex profile walls are:
1. coming in without being trimmed to roof
2. the individual wall layers of the complex profile are coming through as separate components
3. the windows punched through these exterior walls are not coming in at all
This was after I converted to IFC then opened in ArchiCAD to check it out. Since we had successfully made IFCs in R12, I opened one of our ArchiCAD R12 IFCs we created previously, and the complex profiles were handled correctly (windows shown, trimmed to roof, single wall component). Once I found this to be the case, I then saved out a .PLN from our AC13 building as an AC12 .PLN, converted that file to an IFC (seeing if there is something wrong with R13 compared to R12) and the windows DID come-through and the walls remained trimmed by the roofs. However, the wall profiles reset and there was some weird geometry, but 2 of the 3 issues were resolved using R12 to output the IFCs. I am trying various options in the IFC options, but to no avail…
I ask the wizards of ArchiCAD to swoop-in and please advise! Thank you very much!
