how to do parametric streets in archicad?

[Anonymous]

Hello,

I have to do some urban planning drawings in archicad (it may be in 2D only) and in thought about finding some way to parameterize the streets in order to represent at once the street, the sideways and the tree lawns and more important to modify them (like a polyline) without having to redo all the work again and again. The exact contours and calculus in intersections, roundabouts, inclinations are not that crucial at this phase because there will be a specialized road project, this being only the urban planning proposal. At first I tried to do some custom line types from Symbol Line Types but I could't fillet the intersections and couldn't snap in other points than the axis line along with other shortcomings. Any suggestions for that?

Thanks

But the problem with making a road is that roads DON'T follow contours - if you are going change your posting from an abstract ramp and going to become picky with your curbing details, please also acknowledge the various cut and fill procedures road builders undertake to control grading and keep traffic moving smoothly.
