.asm to .ifc to revit. gives strange surface lines

I want to convert a .asm file into a revit file, normally i would insert all files as .ifc into revit. But when exporting from SolidEdge to ifc it creates weird surface lines, as shown below:

Does someone know a solution? Or am i doing something wrong i don’t know about?

I found that exporting true IFC was not the ideal solution, so instead I exported it to a ACIS document (*.sat) document, and imported that to Revit. this solution has worked better for me, thanks for the replies!

Hello Geert,
I think there is nothing wrong with translation.
Maybe someone will have a better explanation, but IMHO when translating to IFC format you basically translate SE files to faceted files (STL for example). After you import IFC file to REVIT, you see the edges of facets (triangles).

thanks for the fast reply,

 

if i understand what you’re saying the export from ifc to revit fails, and not from SolidEdge to ifc? then what would be the solution, using another format?

You're welcome.

I think nothing fails. If you import IFC (facets) to REVIT, you get facets.
I do not know what other formats can REVIT read. Basically in SE the 3D geometry is defined as BREP (solids with material/mass inside). When you export SE file as IFC you get STL (facets with no material inside, only "outer surface" defined by facets).

hmm strange, normally a ifc exists out of solids? So can i conclude this is a lack in solidEdge?

Well, I am not sure if IFC format can be exported as solids from SE. I only know that SE can export IFC as facets.

You can find some information about IFC format fere: https://www.lifewire.com/ifc-file-2621820
Maybe someone else on this forum has more informations about this.

@geert_h  In Solid Edge, change the IFC export option "IFC Version" to IFC4.  The default is IFC2x3 and it does not support BREPs but rather only tessellated output.  IFC4 does support BREPs and thus will provide you with what you are after.


Thanks,

Good point. I am aware about another IFC version, but I did not know that provides BREP result - good to know.
