![]() In this case, I believe it affects it because of the way Revit tries to parse an IfcWall, but since Revit is a black box, I cannot say for sure. Logically, shape representation should not affect colour display. This is the most common reason, I find, for colours not showing. You can see that the green colour no longer shows. Here is one scenario of the exact same file except that the geometry is an IfcFacetedBrep, instead of an IfcExtrudedAreaSolid. And it is these considerations which, I believe, result in a poor user experience. … but, it only works in Revit with a few considerations. Solibri opens and shows both colours without any issue - great job, Solibri! The red is assigned the surface colour directly to the object’s representation via styled item, and the green is assigned via IfcMaterial with IfcMaterialDefinitionRepresentation. ![]() Here is the source scene, exported from BlenderBIM - two IfcWall objects - one red, one green. Best i have seen I have a similar experience as and I also receive IFCs on a weekly basis with these issues. They are doing a really great job working on ifc in DWG ! Geometry is very very good in V20. I would think this shortcoming is in the way ifc works on export and import, not on BricsCAD side. I am not surprised this is same in ifc import in bricscad. I don’t see this in any bim ‘authoring’ software yest. The array (batchnumber, amount and diameters,etc etc) but also one level deeper as single rebar. So from a ‘bim’ perspective the same information should be attached on more the one objects. Because during further modelling and modeluse the array (block in dwg) should be able to be exploded. I am not an ifc expert but i think the name is Property Set right? Crucial data should be available to a set (array) of same objects (rebar) and on the object itself. We need to have a displayed property in the rebar. I think you understand my initial reply and need for information. Allplan is aware of this, but AFAIK they are not going to change this behaviour.įreeCAD (should) and Allplan (for sure does) do export the rebars as IfcSweptDiskSolid” ![]() Thus in FreeCAD ifc importer it is possible to merge materials with the same name and color (If not one would end up with thousands of materials). Different colors for material and shape.īTW: Allplan has ever written an own material for each object. Since I implemented this I have seen more file from other CAD vendors too which shows the same problem. If they are going to fix it, who knows.įreeCAD does shown a log message on import of such case. The ifc development management knows about the problem. I do not know about BricsCAD.ĪFAIK there are two possibilities to give a color to a object:Īllplan for sure has a bug and writes for one object different colors in the material and in the shape. Solibri does show this information, CollabZoom not (support is aware of the problem). Thus the diameter is not a property inside a property set but a geometry information of the shape. FreeCAD (should) and Allplan (for sure does) do export the rebars as IfcSweptDiskSolid.
