For example if the ditch depth is 6’ or less from the turf shoulder, then we use a 6:1 to the special ditch bottom. If it is between 6’ and 30’ from the turf shoulder we show a 6:1/4:1 to the ditch bottom. Anything deeper than that, it’s a 6:1/4:1/3:1.I cant get the first two options to work with Display rules. I even tried to use a null point, have the profile tied to that point via point controls, and then set the display rule saying that if the NP is <=6, use the 6:1. It will only run the first rule when the ditch is 6’ or less. I have also added the rule to the other 6:1/4:1 components.
After doing some more digging. I found this.
Question:
I have assigned a Priority 1 and Priority 2 point control to a point, why does the point not find the Priority 2 control if the Priority 1 does not exist at that station?
Answer:
Priorities in point controls work a little differently than they do in end conditions. For end conditions, the command attempts to solve each priority until it is successful.
For point controls, however, the priority simply tells the program which point control to use in an area where station ranges overlap. Only one point control will ever be considered for a point at each station, so if the point has two controls assigned for a specific station, the priority will tell it which one to use. If the point control with the higher priority can not be solved at that station, then the point controls fails to be applied.
This is what my problem is. In my mind I was thinking that I should be using point controls for the special ditches. So now what do I do? I still have to target the toe of slope at the 3 depths I gave earlier.
Thanks
