This image indicates 10m interval contours at top view.

It is requested to add section lines and/or altitude points at the areas of wind contours and dispersed one. White objects are added entities.

The above objects are indicated at inclined view.

Calculated 2m contours (white) and original 10m contours (orange) are indicated.

One of the NfDesign functions makes it possible to generate TINs with points/vertices.
The contours vertices are transfered to faces.

Color gradation and contour generation can be defined on TINs within NfDesign.
After the definition, a rendering image is calculated.
