I am unable to change the invert elevation on any of the nodes I have placed. I am able to hard key in a value, but after I do so, it changes the invert elevation to exactly 7.25, it does this exact thing for every node. I tried to see if the 7.25 referenced somewhere else, but was unable to.
Andrew:
It seems to me that the definition for this node has a minimum value of 7.25. You could test this by changing the elevation of the node to a difference larger than 7.25; i.e., an invert of 0 and a top of 10. It should "expand" to this difference, but will be unable to "contract" to a difference less than 7.25.

It is able to be a value that is greater than a difference of 7.25. So, for one with a rim elevation of 421.60, I am able to make the invert elevation 0-414.35, but unable to make it any value between 414.35-421.60. I need the invert elevation to be 4.5 less than the rim elevation. Is there a setting to change this?
If the sum of the top 3D cell and bottom 3D cell equals 7.25, then you cannot decrease that total depth. You will need to create a different set of 3D cells that will allow a shallower structure.

Yeah, this is what I suspected and which Karl verified. I do wonder- however- about this set minimum value of 7.25'. Generally, all structures have some standard or "minimum" depth. For instance, our typical grate inlets have a minimum delta of 2'-8". We can employ a structure with anything greater or equal to that delta, but not less than it. 7.25' seems to be a rather intentional number, and such would actually make a bit of sense if it were a sanitary sewer manhole or something like that which would need to have a relatively high delta.
Is this node part of an Agency WorkSpace which may require 7.25' for this particular item, or do you feel like it is a mistake? Do you know who created these cells? Can you have a discussion with him or her about why the node has this depth delta?
I don't believe they are part of an Agency WorkSpace that would require a 7.25' difference. I looked at the Inlet Catalog to see if there was a setting that was causing it to be exactly that value. I created a new set of cells and that did not work. Would it be related to the feature definition of the inlets?
