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.Mark
There is an enhancement request in the backlog quite similar to what you want to do: Enhancement 1032780:Users want to see existing road crossfall in super model (similar to MX crossfall/super checker).
The idea is to create a superelevation based on the existing carriageway and use it to annotate the drawing frames.

Thanks for getting back to Marc. Good to know it's in the pipeline!
Hi Mark,
We also have an enhancement request in to annotate the superelevation based on xfall between a linear feature and the alignment, exactly like what we've been doing in MX for years. This would pick up any draped, etc. levels we use.
We use the concept of a crossfall corridor (with only 2 linear features), created in the alignment file, that uses a combination of point controls and superelevation sections to transition and tie-in superelevation to existing level or extension of crossfall from an adjoining geometry. We then use these linear features as "crossfall control" point controls that dictates the crossfall of all roads and extension of crossfall for all kerb returns, etc.
The problem with this is that the "real" crossfall is not annotated on our profiles...
Regards,
Mark

OK thanks for getting back to me Mark. Yea it'll be good when the enhancement happens and then we'll work from there.Cheers,Mark
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.
