Hi Micha,
I had also thought of that, as I have been proveded with a HQ aerial photo… I’ll surely try it - out of curiosity =]
Update: gave the texture thing a try : it works perfect!
Now, about surfaces problem - the workaround I finally took is a mix of all your suggestions:
- I did cut the topo surface into topic areas (streets, landscape, etc.) using the 2D CAD Data as cutting lines
- After that I used _Smooth, selecting some inner control points (to save time and select only the controlpoints I wanted, I drew a curve around them and used the _SelBundary command)
- Despite of it however, the edges distorted a bit. To fix that, I used the _JoinEdge command on the edges of surfaces, located next to eachother. This command joins not only the Edges, but also the surfaces, so that no gaps are left. (to separate the faces from eachother, just go back to step One,)
That seams to work out pretty well. If you have any ideas in further optimizing the process, let us hear!
Thanks folks and have a nice day!
