This inlet scematic is tough for Inlet Rim Elevation.

Do I have all of the following Rim Elevation situations correct?

Also, does SSA include all four sides of a grate inlet that is not in a curb setting for its perimeter length in its weir flow calculation?

Thanks

Fred -

The Inlet Rim Elevation would the elevation at the gutter flow line.  The Combination Image shows a depression, so you've labeled the top of curb opening.

Thank you for the clarification. Makes more sense.

It just looked like in that schematic that it might have been pointing to that dashed hidden orthoraphic line that goes to the top of the opening.

In response to your second question... I have asked this before.  Not much help, but you can look at the following thread for some more info:

Thanks jm. I understand your frustration..

Yes, responses like  "I think" and "probably.."  are not helpful from the Autodesk Technical Consultant.
