I'm trying to set up an excavation benching template that benches to within 20' of the active surface, then I want the template to continue with a more or less standard set of slopes until the slope reaches the active terrain. I currently have the benching set up as an end condition with a second end condition set up and attached to the benching end condition. The problem I'm having is setting the elevation for the benching end condition to stop and the 2nd end condition to start. I would like to be able to tell the benching end condition to stop approximately 20' below the active surface. Can I do this and how? I'm pretty new to templates so I may be going about this incorrectly. I've attached an image of my basic template for reference.
Thanks,
Jason
