Custom roundabout with multiple roads intersection

[mtizazu]

Hi,

I am having problems with custom roundabout intersections for an interchange. All the intersecting roads work fine but one. If i remove one of the perfectly working roads ( not the adjacent of course), the intersection works but wont work for the removed road if i put it back. Is there a limit to the number of intersecting roads to a roundabout even if the roundabout is big enough to accommodate all roads?   pls see the screen grab.

it should work. @mtizazu , could you please check your roads to make sure they are intersecting? 

if you can share your model, I can take a further look. 

Thanks,

Dear @FrankHuang yes it is intersecting with the custom roundabout. kindly see the .fbx file.

Many Thanks!

Here you can see the two roads intersect but says intersection not supported. I tried changing the geometry of  both the roundabout and the intersecting road.

@mtizazu  tried to model the intersection in your image. suspect that we failed to generate intersection in your case. thus we will need to adjust the geometry of the roads a little bit. 

Very hard to help just viewing images.

Suggestions:

1. first try a larger angle, like 90 degree, to see if we can solve an intersection 

if step 1 works, then you will need to adjust road geometries gradually to get an intersection. 

Hope helps,

@FrankHuang  The Roundabout alignment was looping back to itself, i understood this creates problems on the intersections. I merged three alignments (two outgoing Service Roads and Part of the Roundabout) in to one alignment and another alignment for the remaining arc of the Roundabout as shown in the picture. It worked Perfectly!! Thanks!
