Hi all
I am trying to create a road corridor using a bench subassembly. I have created my baseline at the edge of the ROW and daylighted down to my target elevation (this is created by using a temporary surface as a target). I then wish to create a link to a specified offset so I can insert a road subassembly at that point.
When i attach create the corridor initially using just the bench sub, things are ok. (see pics)
When I attach the link to the end of the sub, the link attaches itself to the insertion point of the corridor and not the daylighting point as per my subassembly.
The final corridor looks like this:
Why is the link attaching itself to the insertion point and not the daylighting point??
Any help would be appreciated

Hi Don
I cannot post the drawing as the company is a little paranoid about that sort of thing. There are DREF's but the corridor does not target those surfaces and the sub assembly is the out of the box Benched daylight SA.
I tried different daylighting SA's and they all acted in a similar fasion except the Basic Daylight which correctly models the corridor with the link attching itself at the daylight point and not the insertion point.
I am using C3D 2014 SP1
This problem happens with the more complex daylight subs. You're attaching to one of two possible daylight points, which may not actually exist in the corridor section.

Hi Steve,
The thing that I dont understand is where I have taken the snapshot picture there definately IS a solution and the link should be at the daylight point but this never happens, why?
It seems that the only daylight SA to work correctly is the basic SA and that there is a fundamental flaw with the other SA's if you want to connect something to the daylighting location.

Yes there is a solution for the example you posted but that solution might come after the first, second or multiple benches, and that's the problem. The point on the DaylightBench sub is only a placeholder in this case, for display on the assembly. When the sub is inserted to a corridor section the daylight point might be the third or fifth or seventh point added. When the software doesn't have a fixed attachment point for the next sub you may get this behaviour.
You could solve this by replicating the behaviour of DaylightBench using generic links and conditional subs. You could also break this into two parts - one assembly that just builds the benches, then extract the daylight featureline and use that as a target for another assembly that builds the rest.
