hi,i'm new to this, but i'm interested in learning. i want to try to make the coastlines in nyc better. i have an extremely detailed drawing of this, in autocad. i am able to export into almost any vector graphics format, however, i dont know what to do to get it into any program that i can start to learn in. any ideas? i cant use publicly available gis data because it is inaccurate for areas with large piers, wharves and landfill - because the "shoreline" it shows is along a bulkhead line, not necessarilly what you'd see from above. one more question for future reference, i use 2d and 3d programs regularly, autocad and rhino, is there any disadvantage to using these, as opposed to gmax? i know i would have to watch polygon counts much more closely.thanks in advancepaul

In the past I have used a program called Dxf2xyz 2.0 to go from AutoCAD to an output surfer .bln file. Sbuilder can read this format and generate VTP coastlines.Available here:http://www.guthcad.com/downloads.htmscott s..
