Hello,
I using InRoads V8i SS2 and I'm trying to construct a template that works with two target surfaces.
For example, in a project with two DTM surfaces loaded (existing ground and rock surface, ~ 3 meters above existing ground),I have to configure a template respecting this slope rule: cutting existing ground, the end condition slope is 300%, and when is cutting the rock surface, slope is 500% (please see picture below).
I tried to use two end conditions, each one with constraint of slope and project to surface set.
I didn't get a good result. I need some help to set that..
And another issue, in the case when the rock surface doesnt exist, is necessary to creat a third end condition?
Regards.

Hi Douglas,
Have you tried using contrained components (not end conditions) and use the constraints of 'Slope' and 'Project to Surface'. That way you can choose the 2 surfaces that the points will search for.
Cheers,

If you are using end conditions you do not need to use the project to surface constraint. The end condition will do this because it is an end condition and is looking to solve based on a set of rules. The rules are the constraints and the component order. In your case you could use two end conditions. First from the shoulder at 500% with a vertical distance of 1. Set end condition to infinite and it will project at that slope until it finds the rock surface. Start a second end condidtion component at the end of the first with a new target of existing ground, slope 300% vertical distance 1 and end condition infinite.

I agree Marc, I like that approach and it also allows for easy 'testing of the end conditions' inside the ITL. Douglas, make sure you create two back-to-back end conditions with each using the appropriate Target Surface with infinite on (both can have a priority of 1 in this situation). To address your 'What if only ground surface is present' situation, I'd add an end condition component coming off the hinge targeting the ground surface and give it a priority of 2 with infinite on, basically your last resort solution.
Hi!
Great! I liked all the sugestions!
I made it using what Marc and Brandon said.
My mistake was on setting both end conditions with "project to surface" constraints.
Thanks a lot Marc, Brandon and Marc!
