3D Contour Model within Minutes

Working on a contour model is very time consuming, and most often the time, 2d cad files only come with incomplete information. The Contour Generator works with any 2d information including contour lines, spot elevation text/point, and boundary curves, and produce continuous contour line approximation, smooth Brep (closed polysurface), and stepped model. Depends on the size of the model and given information, it only takes about 20-30 minutes to turn your incomplete 2d information into 3d contour models with layers of useful information for planning, design, engineering and construction.
