Modelling existing superelevation and showing within the schematic

Hi,

I am wondering is there a way to show the existing superelevation of a road within the superelevation schematic drawing frame.

For example. 

When using a corridor and applying a design super elevation using the superelevation editor this works perfectly. The schematic drawing and superelevation editor reflect the design intent. 
If for example, the first section of the design is to match the existing road conditions, including horizontal/vertical geometry and crossfall, is it possible to show this within the superelevation schematic drawing?

For example, when using MX, the superelevation schematic takes the levels off the road edge string and calculates the crossfall. So if I were to drape the road edge string onto the existing ground surface, this would show the existing crossfall/superelevation.

I like using the 'Profile by slope from element' for smaller detailed sections. And some times, I have to work with imported 3D elements. However, it seems I wouldn't be able to show resultant superelevation/crossfall within the drawing.

I’d appreciate to know what others think of this.

Apologies for the confusing description.

  • Digging this post up from the past. Does anyone know if this was ever sorted or is a workaround needed? I'm regularly independently grading edges of road by using two seperate alignments, particularly when tying into existing kerbs etc and am having trouble showing the slope/crossfall between the two alignments that define the edges on a profile.

    Its a critical part of our design output so I'm hoping someone can provide a solution.

  • Hi Aaron,

    No movement on this yet - we still use the concept of a Crossfall Corridor for design as noted above. There is an idea you can vote for here: Ability for Superelevation Lanes to | Bentley OpenCivil Ideas Portal (aha.io) that will hopefully expediate the ability to get crossfalls from Linear Geometry projected to Superelevation sections.

     

    In the meantime, this workflow may help:

    • In your Alignment file, create a Corridor that includes a template that has a simple LHS and RHS points, set to standard crossfall and including Superelevation flags. We call the points XL and XR (brought over from our legacy MX convention).

                

    • Assign your Superelevation Lanes to this Corridor and then use Point Controls to get the crossfall\superelevation you need (we use Point Control priorities to avoid playing with station ranges, etc. but whatever works here).
    • In your corridor files, make sure your standard Templates include an XL and/or XR point and set all your lanes to use Vector-Offset for slope between this and your Origin point. Then all you need to do is Point Control (both) the XL\XR points to your Xfall Corridor XL\XR features.

                

    Another major advantage to this workflow is that you can also grade intersection fillets using Extension of Crossfall from your through Control line and the Xfall Corridor XL\XR feature and it will stay in sync with any crossfall changes you make to the through road - a big time saver and actually using the smarts of the software as intended.

     

    We have been using this process for years and not too sure how anyone can deliver using the standard Superelevation Section workflow. It is terribly inefficient for real world projects in my opinion.

  • btw we are still waiting on an enhancement to show Crossfall between Linear features on our Profile Drawings, so in the meantime you'll have to fudge in numbers into your superelevation section to get them annotated. Hopefully would be not be needed if ability to get projected crossfalls from Features to Superelevation comes in (and gets annotated as part of that)
