Intersection problem (different assemblies)

[Anonymous]

Hi, All!

I've been playing with intersection for quite a while trying to achieve the result I need and failed miserably.

Please help me solve the problem (please see attached image):

Here I've got a T-intersection. Primary and secondary roads have different assemblies. I've put annotations and sizes on the drawing. So basicaly I need my Primary road "Sidewalk" and "Grass strip" to be cut off with curb return allignment. I tried to draw polylines to use them as targets but when I set Grass strip target to pl, the rest of corridor region bent towards the center of the intersection. I assume this happens because CVL3D calculates distance perpendicular to curb return alignment (red dimension) while I need it to do it perpendicular to target pl (green dimension).

If I could instead of setting pl as a target just gradualy change my Grass strip subassembly width from 3m to 0, that would have solved the problem I believe.

Is there a way to do it without using subassembly composer (as far as I learned from topics on the forum, subassembly composer is the only way to create variable width subassembly)?

Thank you!

Dimitris.

Using a polyline would be easiest because you can simply target that object. If you want a subassembly where you are able to give it inputs that make it taper on its own, without targeting the polyline, then, yes, you should use Subassembly Composer.
