Hi,
To summarise; needing to create a 3D string which represents (for example) the edge of a station platform - set co-planar to the running rails. Currently playing around with templates and roadway designer which works well when there is zero Cant.
With Cant is applied to an alignment, the roadway designer does not register the cant value(s) - thus always outputs zero Cant. How do you fix this? Is it something to do with the "Superelevation" tab within the roadway designer? Unfortunately, whatever way i export out a cant report, the formats available are unreadable to this tool?

Couple of things to check
Do you have a cant alignment designed in BRT/PRT/InRail as a child alignment of your Horizontal Alignment in your alg. (see images)
The next thing to check is if you have applied Point Controls to your Corridor in the Roadway Designer.. Once you have created your corridor, and then created your template drops, you can apply point controls to the right and left hand rails to rotate them as per your cant alignment.
Go to Corridor - Point Controls - and give your control a name (eg. Platform 1 Cant). Underneath "Mode", tick the box for "Vertical" and select "Cant" from the Control Type drop down list. Then select the relevant points in your template to refer to the Centreline, Right Hand Rail and Left Hand Rail. Then process your surface and see what happens.
I have a platform construction template that I use for this to define the line of copers along a platform. The CL moves along the Horizontal and Vertical alignment, and the 1-LH and 1-RH points move via point controls with the Cant alignment, then then the 1-COPE-EDGE-R1 point moves relevant to the 1-RH point to set out the coper edge alignment. See attached image for information
Hope this helps

A very good way to model the platform in "roadway"; but isn't "1-COPE-EDGE-R1" dependent on both 1-LH and 1-RH, when cant is involved? (see illustration below)
If to create the platform-edge alignment is the only goal, I'd however prefer using "View 3D alignment" and set the different H-/V-offsets from the track-alignment upon the elementtypes (i.e. linear, curve or transition curve).
Thank you for sharing your ideas!

Hi, LIPeng! To achieve the pictures result you need to use Constraint "Angle Distance" And to chose 1-LH and 1-RH as Parent 1 and Parent 2. Note: You can use it when you haven't any other constraint applied!
