I’m trying to export a landscape, created in Viz from polylines originating from a dwg map with the lines at different z-elevation.

When I try, it says there are to many vertices. Is there a way to simpliefy the landscape object to get it to export back to a dwg or dgn file ?

Is it a mesh? If yes, you may try to use Optimize modifier.

Ok, thanks - I’ll try that !

Worked like a charm !

Thanks !
