Yes it worked..... I thought that I should erase the dwg since your help worked. I can upload it back...
I didn't know all the options for that command.....
You save me a lot of time.
Since I know that you work with LDD (or LDT) a question for you. I'm doing a 3d presentation for a subdiviaion... All the roads are 3d polylines ( cl, eop, curbs, sidewalks...) to create my TIN.
Now the presentation is gonna be in 3ds Max or Autodesk Viz...what is your opinion should I generate the TIN as 3dface or Polyface Mesh. I understand that a Polyface mesh cannot have more than 30000 vertices?
Or is there a way to represent that TIN as you would represent it with 3D Grid from civil design (cross sections)
