We received an IFC model from an engineering firm and would like to do a clash control. The problem is that a lot of the pipework is being cast in to the concrete, and so currently running the clash detection gives about 2000 clashes. They have connected IFC information to the model to clarify if it's being cast in or not, but I don't know how to access it in Openbuildings.This is how it looks in Solibri:
Is there any way to just reference the IFC file, use the "suppress clashes with elements that have a specific property value", to prevent this? Or are there any other suggestions on how to approach this.Of course I know the easiest answer is to ask the firm to supply the files with either the elements on separate layers or even a separate file, but if possible I would like to do it ourselves to prevent any additional charges.
The clash detection dialog enables this, add a new Rule (1), select a Property (2), Change Class (3), Change Schema (4) to BuildingDataGroup (5):
Then filter by a Catalog Item Type, I chose Wall, then selected Part Definition (6):
Appropriate choices for a referenced IFC should be avaialble.
Thanks for the very clear and helpful information.
Unfortunately, either they are not using official classes, or I can't seem to find them or find the 'text' property in any of them. Underneath the element info I get out of it. Do you see any way I still can get this information out of it?It's just frustrating because they use this method with a lot of different other CAD programs, and there it seems to work flawless.
With kind regards,
I happened to come across this post and was curious, so did a little investigation. Would something like this work?
