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

Akande, take a closer look at the constraints on the bottom of curb at the median. make sure the top of curb is constrained horz and vertical to the bottom of curb.
When fully superelevated where are the points of rotation? At the median edge?
Did you define separate supers for the left and right side of the highway?
Looks like the center of the highway could use a vector-offset constrained between the median curb and the outside curb if the center point slope follows the left and right side.
In Super, you would only need to create super lines for the outside and inside curb lines.
Could you attached your .itl and .ird file?

A few more things to consider.
Rollover locks are not needed in this case since there is no shoulder. The rollover locks are applied to the segment just outside your backbone. In this case you have curb, no rollover needed.
InRoads triangulation will not support vertical faces. So your face of curb component should have a horizontal offset from the bottom of curb to the top of curb of .01m or .001m. This is set to allow triangulation of the top surface. To check this, have your display triangulated surface checked on in your Roadway Designer Tools>Options.
Your bottom components points should be constrained Horizontally and Vertically to the point above. This is critical when applying superelevation. Your should also experiment with the vector-offset constraint. This is a very powerful constraint in a highway template with Superelevation.
The center points of your divided highway lanes, are they really needed? Not knowing your design I would consider removing them if they provide no value to your design. If they are in the template, to supports graphics in Microstation for a drafting line I would consider removing them. Parametric Constraints can be used to control pavement widths.
Bottom Line - Make your template simple as possible.
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.

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 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.
