Hi,
I am new to openroads desginer. I have been working with Inroads SS10 and SS2 earlier.
A variation i noticed in ORD , point control start and end chainages do not add additional drop points to the corridor. Key stations have to be added.
I am stuck with Linear template. There is no option to add additional point / Key stations. Due to template not dropped at the point control start end locations the model does not look complete. Gaps are formed.
How do i add key stations to Linear template or add Event point to the alignment.
I am using Openroads 2020 release 2
Thanks in advance.
Thanks
Now that I think about it, you could even make a "null component" that is set to "do not construct" at the begin and end points in your template builder, give one of the constraints a name of "Key Station", and then just use that parametric constraint to drop in key stations. This way you won't have to worry about accidentally changing something you didn't intend tot change, and it will be clear in your corridor objects menu where the "key stations" are.
While not ideal, I have found a trick to add "Key Stations" to linear templates without the regular tool. If you add a parametric constraint to one of your constraints that you know you don't need to change, you can force the template to process at the begin and end station of that parametric constraint. For example, if your sidewalk is constantly 5' wide within a station range and you want to add a "Key Station", you can begin a parametric constraint for your sidewalk width (set at 5' so nothing actually changes) at the station you wish to add a "Key Station" to, and whatever you set as the end station will also get processed at that station. Hope this helps!

A couple thoughts:
1. You can create a corridor model using the exact same template from the ITL file that you used for the Linear Template. Then, you have all the corridor modeling tools available, including Key Station. If you go this route, however, you may not need Key Stations for your stated purpose. If you enable External Control Points in the Feature Definition Properties under "Processing & Critical Sections", then you will get template drops at the Point Control stations automatically.
2. Perhaps you need a Linear Template instead of a Corridor model because you need the "sweep angle" ability of linear templates at a sharp angle point that has no radius? If this is the case, as a work-around, can you use a Linear Template to model the location near the sharp angle point and use a corridor model for the rest, including the location where your Point Control is located?
Just some ideas.

Thanks Shawn.
It definitely helps. Yet it's difficult if we are in need of template at a particular chainage.
