One part - a free polygone with editable hotspots in 2D and 3D creates a street by using a Profile-manager-profile and curves all direction-changes with bezier-curves. It also creates in 2D a "sectionview" following the whole polygon with all Height-texts in a table - if you want that. In this section-view - its possible to adjust each Z-height also.
One other part is a ramp with the same features - and the possibility, to round the edges in Z
One other part is a T-crossing with profile-manager-edges (each diffrent) and adjustable in every way.
