IFC file exported from Archicad to Revit, some elements are missing.

[Anonymous]

Hi everyone, 

So one of my colleagues uses Archicad and they designed a topography  model in it, and they exported a IFC file. 

However the geometric lines are not correct, its all triangular form. So basically the contour lines are not correct, so is there any way to fix that? I've attached a image below to help understand my circumstance. 

Thanks

Sounds like you are referring to this setting is Visibility and Graphics Overrides

Yours may be checked

Yeah, i tried that option but it's already unticked before i even could untick that option

May I see what you are referring to? A picture is worth a thousand words.

Sure, here it is

Ask him to export the top to DWG instead, then link it in Revit and create the topography surface from import.

Pretty ugly.  Let's try post the actual IFC.
