Prodded by a comment on the IFC export / import capabilities of ACA 2009 and RAC 2009, I exported the out of the box "c_condo_complex.rvt" file to IFC and imported it in ACA.
This is how it looks in RAC. (Three floor plans and iso view)
This is how it looks in ACA. (Three floor plans as iso views and a View dwg that has all these levels xrefed into them.)
I used the "create new project" option.
The results are NOT at all satisfactory. However, when I used the split walls and columns in Revit, I got this. I guess, this should work, if I want to give this IFC to my MEP consultants who are working with AutoCAD for MEP. It brought walls, windows, doors as ACA objects. (style names are IFCStyle1, IFCSTyle2, etc.)
If anybody has done this or use this function often, please enlighten me. Some issues:
- Some walls are missing.
- Roof and wall interaction is not handled properly.
Surprisingly, when I imported the same IFC file into RAC 2008, it looked like:
This result had similar issues like ACA. (same exterior walls missing, roof/wall bad improper interaction) It brought back same wall styles (as in RAC2009), etc. Which is great, but it seemed to happen only on the first floor level. Upper floor windows and doors have become in-place familes!!!
