Corridor model ending against a Feature line

[jfquevillon]

Hi,

I'm new to the forum and I'm having difficulties finding a solution to my problem!

I have two different corridors next to each other and I need to make them finished at an angle against a feature line (shown in green). Is there a certain sub-assembly a could use for that and how to target it?

I'm using C3D 2018 by the way!

Thank you!

I think the way to handle this is to draw a baseline across the end of the 2 corridors where you want them to end. Then you would apply an assembly to that baseline and target the ends of the corridors.

Hello  jfquevillon,

I recomend star or finish your alingnment perpendicular to green line, perpendicular section could be small, maybe 1 or 2unit of your drawing. Rebuild your corridor and this sould fix your issue.

Thank you for your quick answer

I still dont know exactly how would you do it when using a new Baseline?

How do I set my sub-assembly to tie to that new Baseline? Can you me more detail on how to proceed?

I have done that specially for bridges.

Every alignment needs to be longer.

Then you need an auxiliary subasssebly (make it in SAC) which have an offset target and no draw the link, just a point on the origin and  second point on the offset target.

Then, in the assembly, you put this subassembly the first one and the second subassembly (lane, etc..), attached to the second point.

In your case, the offset target will be the green line and the white line (edge of your lane which you have to get as a polyline and extend to the green line).

The idea is filling that triangle using 2 entities for the same ofset target. The concept is very similar when you are doing a manual road intersection.
