3D Terrain object can be created by defining a boundary and entering topographic contour lines

Terrain object has next properties:

• The shape of a terrain is defined by defining a boundary
• After starting the terrain, the outer shape (boundary) is entered by drawing a polyline
• Contour lines (isolines) are drawn as lines assigned with elevation.
• Isolines are automatically lengthened up to the outer contour's boundary or are cut off at this boundary
• Contour lines can also be closed.
• User can edit contour lines by starting the terrain's Intelligence dialog
• The contour lines are shown in a list in the dialog box, and can be selected accordingly
• Import of DXF lines supported.
• User can set quality of terrain’s geometry to optimize it or set high 3d resolution
