We work with BricsCAD BIM, mainly with 3D solids objets. We have a problem of file dimensions: we need to not exceed 250 MB by contract. This starts to be really challanging since our models are growing and gaining detail along the project. We even try to use some specific IFC compressors but the result is somenthing around 90-95% of the original dimenstion, that is not resolutive.
We work already with splitted model. (one model for piping, one for structures, one for equipements, one for instrumentations etc etc). Further model division could be a problem.
On "settings-->BIM-->Import and Export-->IFC-->Level of tassellation" we already set the option to LOW. But that is not sufficient anymore.
We did several export trial to understand what is the critical factor that makes file dimensions grow. We didn't find any particular dependence on number of surfaces, numbers of nots or number of solids. It looks like everythink contibute to file dimenstion grow.
On the other hand we have collegue that works with Tekla and Revit: a "same level of complexity" ifc model have a much much smaller dimension.
Does anyone know:
1) Which are the best settings in BricsCAD BIM in terms of file dimension export? Any suggestions?
2) What are the critical factors in 3D modelling in BricsCAD BIM that makes the dimensions grow?
3) Why other software have best performance in terms of file dimension export?
4) Any other miracle?
Many Many Thanks!
