Hello guys
Am working on a design, a 4lane divided highway template with raised median barrier and kerbs together with cover drainage, in which the shoulder and the drainage are together, so i built the template and applied it to the corridor, but when i tried to calculate the superelevation for the curved section, i discovered that while in the superelevation mode my template was not well interpreted by inroads, it was picking templates points that are not needed to define the section of the road to be superelevated, it was picking points that were directly above the required points. it would make alot of sense if i include a picture of my template so you guys can have a look at it.
this is a link to the picture of the template: https://hotfile.com/dl/154152787/d2b0877/SUPERELEVATION_PROBLEMS.jpg.html
Please am currently stucked in this stage, pls any suggestion on the possible way to build templates for divided highway with raised median that includes drain and shoulder, just as i have it in the picture above, and it will be able to calculate the superelevation. what i discorvered is that superelevation wizard will always look for all the top points in a template, but from the template i designed some of my points a directly below. so please how do i solve this problem.
Thanks to the entire house, looking forward to your replies
Regards
Thanks joe pls could you attach the template file to your post with the built in attach file tool in the forum, so that i can have a look at the modifications that you have made to it. in super elevation i normally use the table method, because it is faster for me.
Thanks once more

I fixed the Template in question by removing the CL points and changing the face of curb. I don't know how to send this to you because this forum does not allow e-mail addresses to be published.
I couldn't check the .ird because i need the .alg file as well.
In the Superelevation, are you using the table method or AASHTO?
For the Template I removed the center points L_CL AND R_CL and constrained the outside curb lines to the inside curblines with horizontal and slope. This will work as follows when defining the superelevation points. You will need to create 2 separate Superelevation entries. 1 for the left side and 1 for the right side.
NAME - Left Side of Highway
CROWNPOINT - L_EOP
LEFT RANGE POINT- L_EOP1
RIGHT RANGE POINT - L_EOP
For the right side of the Highway
NAME - Right Side of Highway
CROWNPOINT - R_EOP
LEFT RANGE POINT - R_EOP
RIGHT RANGE POINT - R_EOP1
When finished you should see in your point controls for Super, 6 lines of Super
HTH

joe thanks i never knew that inroads cannot triangulate vertical faces i guess i still have alot of work to do, in terms of the template technologies. Thanks alot for all your expertise, Pls for the template file i attached look inside the AA TEMPLATES FOLDER and open the MAIN CORRIDOR TEMPLATE, this is the one i initially built as required by the design. other ones are just modification as i was looking for a possible solution.
Thanks Alot Joe.
yes i agree with you, for the super i only need the outside and inside curb lines, but as i mentioned before, the superelevation section dialog box is not listing those points, and they are key for defining the section to be superelvated. i already attached my template file and the roadway designer file for you to have a look.
thanks
Joe thanks again for your quick response, here is the template library file and the roadway designer file, if you check out the superelevation image above you will see what i was talking about.
