I'm having issues with building corridor surfaces (please see attachment). More and more I'm finding parts missing from the triangulation surface. Given it occurs mostly at Junctions I suspect my assemblies may be faulty, but having inspected them i can't find an obvious problem. Can anyone please help?
Draw a polyline around and add to the surface as a show boundary - this may not get to the root of the problem (why there are holes) but at least you'll get a surface
Thanks, I had a go at that already which is a decent workaround, but as you say it doesn't quite solve the problem. My gut feeling is that it's an issue with the assembly, perhaps I'll have a closer look when I get a moment.
I can't say if this is your problem. But I've had similar errors when I had a the curb vertical or undercut. Once I fixed it in the assembly the wholes were gone.
Had a bash at that but unfortunately it was to no avail. Thanks for the tip though. I may have another attempt with another kerb/curb set just to completely eliminate the possibility.
I had something similar happen when the corridor was set to match existing surface at a set slope from edge of road. Got everything looking good, then had to update the profile. Elevations changed, slope matches at a different point. Suddenly the boundary I had for the surface was wrong, because the matchline moved. Ended up with missing triangles similar to yours.
I guess this is way too simple a problem that you wouldn't have caught it, sounds like you were already looking into the boundaries....but just adding my twopence worth of thoughts to the discussion.
