Archicad can't import a good already created mesh but can create its own bad one?

[TazzieFez]

Hey People

So I'm a surveyor. I can create a very accurate mesh of the existing ground surface (the perfect way to start a design). But there is no native way to import a existing TIN/Mesh into Achicad? Through DXF, LandXML or any other common CAD format? 

So I can create a xyz points file and import it and create a mesh from it, but it is a bad mesh and is not accurate because it doesn't use breaklines. Breaklines control which points join to which ie a retaining wall has a top and bottom breaklines. If just using XYZ like the Interoperability > Place mesh from surveyors data method, then a retaining wall looks like a sharks mouth of bad triangles.

I have seen the LAND4Cad add on, but is there no way to natively get good 3D survey data into Archicad ?

Or a Mesh.... but you will need the 3D faces in the DWG... Archicad won't do magic ( most of the times)

THANK YOU - It works very smoothly! Wish I had known this like last year! 😉
