Our second question on templates is in regards to end condition exceptions.
In our backbone template, we have the edge of our pavement structure extending to the front slope of the ditch using the constraint "Vector-Offset" on two points (the edge of pavement and bottom of ditch). However, when we have an end condition exception that changes the ditch from say a straight 4:1 slope to a benched 6:1 then 4:1, the pavement structure does not get updated (even though we've placed a dummy point at the slope break location with the same name as the point constraint in the template).
We are trying to figure out how best to draw in special ditches that have their own alignment and profile? What do other people use? Several Templates, end condition exceptions, parametric constraints, etc etc. Our ditches are rarely ever constant side slope, offset and depth. Any advice is helpful.
Thanks.
Thanks for the posting. I tried the Style XYZ targeting option since we have unique alignments for the ditches which are not parallel to the roadway [since we don't have a constant front side slope] and it seems to fix the issue below as I indicated with end condition exceptions. Before we were using the Alignment XYZ -- The "issue" with that was you had to specify a unique ditch chain/profile so you would have to have multiple templates, end condition exceptions for every ditch section, or multiple end conditions in one template on top of one another, where as the style method is more open ended.
The end condition videos were very helpful and I think that answers my questions about the if/then statements; but it'll take me a while to digest and give it a try. Any more videos in generating templates, parametric constraints, point controls, etc. would be VERY helpful.
Thanks again!
Chuck,
I get an error when I pasted your link in my browser, that's why I was hoping to somehow download what you have posted via a public login or something.
Thanks!

I was able to right click on the links and save them to a local folder.

Jon, my apologies. I will try our Bentley FTP site. I have also included a couple of others you may all find helpful to get you pointed in the right direction.

Hi, I was wondering if you would be able to post these videos again. I am trying to add special ditches to my templates and any help would be great. We have ditches that have variable foreslopes and variable bottom widths. I would like something as generic as possible, yet covers every condition. Thanks!
