continuing with special ditch grade...

Brian Nilson

with you all's help I have been able to set up point control for special ditch grades in my template end conditions using point control....but I need to take this further. is there a way to create the end condition so if there is no special ditch grade the end condition fails? In criteria I could test for the special ditch grade and if it was not there do something else. in my current end condition I have the FB ditch the first priority and a fill as the next priority. if there is no special ditch grade the template creates a FB ditch based the dist and slope defined in the end condition instead of creating a fill. Thanks for your help!

    Ooooh! I'd like to know this as well.
    Is it possible to set up an end condition based on a control such that, if the control doesn't exist the end condition fails?

    Create a Null Point off to one side at elevation 0 in the template. Create a display rule that checks to see if the vertical distance between the Null point and your Template Origin point is not equal to zero. When it is equal to zero, you do not want the elements displayed, when it is not, you want them displayed.
    You might need some other end condition to display when the other in not.

    brand new to rules but sat and watch some videos today to get a handle on it. I set null pt as you suggested and when a special ditch grade was found the ditch was created the null point moves. the logic is setup so if the anchor pt and null pt are not equal the fb ditch is created. the other thing I am trying to do is have a fill if there is no special ditch grade. since I set the priority at a higher number for the fill I assumed that fill would show up when no special ditch grade found. it did not. I then set up a rule for the fill component that if the null point I created did not move vertical then it should draw a fill. it still didn't draw a fill. I must be missing something. thanks for your help. brian
