Import an Archicad model to further editing on sketchup

[chiwi_95]

Hi there, i'm more or less new to SU so i'm kinda stuck in this.

I've modeled a terrain on Archicad and imported it to SU, i was trying to use Sketchups TIG Slicer plugin over the model, but so far i could'nt. I was wondering if there is a way and if it is, how can i do it?

The imported file was triangulated so i was wondering as well, if there is a way to make one regular surface

Thanks in advance
