Why does each contour line appear to have hundreds or thousands of vertices (points) along its length?
Try to clean this up at its source. Some programs which automatically trace or allow you to trace contours will place unnecessary vertices, even along straight lines. Exterior3D doesn’t yet have a means to filter polys, but your CAD or tracing program may. See the question on tracing a map. (See instructions below.) These solutions refer to the following information where detailed instructions are given, such as prepping a file. It is essential that you take a few minutes to prep your file.

REFERENCE SECTION DWG AND DXF: DWG is AutoCAD’s native format; DXF (Data Interchange Format) is the most common industry-standard for transferring between CAD and similar programs. DXF was created by Autodesk, the maker of AutoCAD. DXF files can be either binary or text (ASCII). Exterior3D can only read a text DXF file. You can use any text editor, word processor, or even a spreadsheet program to determine which kind a DXF fil
