On a roadway I am designing using Corridor Modeling & Roadway Designer I am unable to generate the limits of construction. My proposed templates are created properly (I believe) with one of the end conditions as "End Condition as Infinite". They look correct in both Roadway Designer and when I generate them onto the cross sections. In Roadway Designer I dropped the templates at 10 ft intervals, my cross sections are at 50 ft intervals. Also, the proposed cut/fill slope lines intersect the existing surface (or so it appears).
In the Limits of Construction dialogue, I select the existing surface level for the "Existing Ground Line" and all of the proposed element levels for the "Proposed Finish Grade". Tolerance is set to 0.10. When I hit "apply", there are only a hand full of sections that process correctly (for a 5 mile section of roadway). For the other sections that don't process correctly, I get one of the following messages:
'Unable to find more than one point of intersection between Proposed Finish Grade & Existing Ground. Check your tolerance"
or
"XS-DANGLT Proposed elements do not tie to the existing ground on the left-hand side of the the cross-section at station:"
Is there something wrong with my workflow? What do I need to do to be able to generate the limits of construction lines?
TIA
what software/version are you using?
For more information about the Road and Site design tools, visit the Road and Site design WIKI at: http://communities.bentley.com/products/road___site_design/w/road_and_site_design__wiki
Microstation SS2 V08.11.07.443
Geopak V8i SS2 V08.11.07.566
I changed the tolerance as suggested (and to 1.0) but still get the same errors.
The tool finds the limits for some cross sections but not others.
ok. what is the vertical distance between your xs cells? you have to analyze one of those that doesn't work. turn off levels in microstation and start level by level make sure that you get a good connection. doesn't it give you a message for those sections?
The vertical distance between XSs is 500 ft.
What exactly do you mean when you say "get a good connection"? I checked the intersection of the proposed linework and existing ground sruface and it appears to be ok, especially within the tolerance set in the "Limits of Construction" dialogue.
I don't want to have to go thru 500+ XSs checking each one to make sure the proposed lines intersect the existing ground surface.
the tool works with levels, make sure that the levels you are calling out for existing and proposed are correct. you should check the xs where you are not getting the limit
