To see how Contours are formed, click here to see an animation, or click the links below, to see a typical screen at right.

1. Start with the points in the job database.

2. If you want to use all points in the job for your model simply go to Contour - Form Model, 
if all the points in the job are not applicable, 
Use Contour - Surface Parameters, and Surface Point Selection to select the points you need, then form the triangles.

3. Once you have a triangulated model select Calculate Contours and you can then position the labels for the index contours interactively.

4. If you wish, you can display bands of color to represent Height Ranges.

5. You can also produce a
3D view of any model, which you can shade, rotate and walk through.
