contour mapsdownload a free demo version now!
This useful application can easily produce 3D contour maps and cut-sections from a few data. You get a 3D-mesh AutoCAD entity and from this point, you can make renderings to use in presentations and level lines visualization. The application draws automatically selected cut sections over the 3D model or in a 2D representation. Besides, the application calculates the volume between the surface and a specified horizontal plane.
A set of drawn points is required as unique data. These points have to correspond with the field level survey.
The user defines the density and the corners of the mesh and the application draws automatically the contour. The application draws the 3D mesh by using an interpolation function, which takes in consideration all the data points.

level lines
|
The user can obtain level lines (contour lines) by adjusting clipping planes (DVIEW or 3DORBIT AutoCAD commands) or by drawing 3D faces in the level desired. |
|
profiles
|
If the user requires a cut section, has to draw a polyline in a plant view. The application reads this entity and draws the configuration of the profile obtained by cutting the contour with a vertical plane over this polyline. The polyline can be straight or any shape. In this way is very simple for example to get the profile of roads across the model. |
