I am unable to create a site model. Vectorworks only lets me modify them. I have a tab delimited text file with 3 dimensional coordinates for a bunch of topo points and i wish to create accurate contour lines. But whenever I plot these points in vectorworks it will not let me create a site model, only modify the site model (the create site model option is greyed out and unselectable and no matter what I try I can not select it at anytime), although I have not yet created one, only plotted the points. Why is this? Any help would be much appreciated. Thanks a million.
