Creating template using offset level

Matt,

You can select any alignment to use for the template as long as it has a profile. You will need to make sure that the template is defined in such a way to be built off the type of alignment you are using. You could also use the centerline of your road, and then use a point control to move the point within the template to match the sawcut line you are creating. I'm assuming though that you don't have a centerline yet, which is why you are asking this. If you're new to OpenRoads Designer then I recommend searching through out Wikis and training to make sure you are implementing proper workflows. https://communities.bentley.com/products/road___site_design/w/road_and_site_design__wiki/42397/corridor-creation-manipulation

Hi Holly, 

i tried going the route of control points but it didnt seem like it was working the way i wanted to. So we do have a centerline and what i ended up doing was i created a few different templates and offset the tie in point of the pavement (the sawcut line) at different offsets (-29,0) for example. I was able to model the corridor, however when I ran the cross sections, points were not tying in to either the pavement or the end condition. To make things more complicated, we have surveyed pavement, however we are tying into Lidar for the end condition. I figured out how to specify tying into the lidar for the end condition (although from the sections I ran it only successfully tied in maybe 1/3rd of the time) but I couldn't see how to specify tying the pavement into the survey terrain. Any suggestions for this? If not, is there a way I can manually manipulate the cross section so that it updates the proposed terrain as I go along (extend line on end condition to tie in or move the section up slightly to where it hits the existing line?). I could ask many more questions ha, but this is where I am at right now. Below is an example of what I am coming up with. Thanks!

You can use target aliasing in order to tie your end conditions into more than one "existing surface". Target aliasing allows you to define more than one object as a single target. You may want to look that up on here, in the help, and on YouTube. I've used it with good results, but it's been a minute and I don't want to get into too much detail.

You can manipulate your template in a few ways, if there are spots that just don't work with the template as-is. End condition exception might fit your needs. When you define an end condition exception, you change the end conditions on your template - but only for that station range.

You can also define another end condition in your regular template for a second side slope that can solve in case your first one doesn't. Check the Help on end condition Priority. You can set up several different slopes: Create 6:1 slope. If 6:1 doesn't solve, create 4:1 slope. If 4:1 doesn't solve, create 3:1. And such. You may still have a few regions that don't want to solve at all, but that usually takes care of most of mine.

For getting things to tie into the ground on the "inside", you can't just give them a horizontal offset because that's all they will do - go across. They won't go up or down. I usually define a feature line for my sawcut line and drape it on the existing terrain to give it the proper elevation. That way I can target that feature line both horizontally AND vertically to get my tie in onto the existing surface.

I hope any of that helps!
