We have started using BRCM models along with OpenBuildings and OpenPlant models on multi-disciplinary projects. I have found some difficulty with the assignment of materials in the BRCM files, as well as with some nested or grouped elements in OpenBuildings files, can anyone shed some light please?
In our OpenBuildings models, the materials are assigned by the data set using Parts and Families. Elements that are grouped (I really hate Ctrl-G!!) or nested cells resist any materials being assigned or attached to them, but in OBD if they can be dropped I can get around it.
The parametric cells in BRCM files are more troublesome because I cannot drop them without losing their integrity. Even assigning the materials by means of levels does not work.
Are there any suggestions for how materials in BRCM can be managed and integrated with the OBD models?
I don't know much about BRCM but I have seen issues with parametric solids losing materials, especially when placed as cells. I will make a test case and ensure we get a bug for this problem in our backlog. Dropping the Parametric solids to Smart solids should work as a workaround.
Nice to have you back!
Our local Bentley ORD expert has resolved the issue for the terrain models, the material can be assigned within the DTM itself in ORD:
With regards the BRCM elements, this can be addressed by assigning materials to the levels in BRCM itself rather than trying to assign them to the reference from within OBD.
I have indeed been dropping the parametric cells, but as you can imagine this is not a desirable workflow - I would be most grateful if this can be fixed.
Hi Wendy, I was able to provide Nilesh with steps to reproduce the problem, and a bug report was made. The developer already has a fix for the problem so it should be fixed in the next MicroStation update
Great news, thanks Jerry!
