Creating templates - two surfaces (targets)

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.
