Thank you for your interest in my question. Referencing the images I attached is an example of the problem I have. I made 2 fittings: the first is a 10"round 90 degree elbow and the second is the same with 12 inches of straight add to one side. The first table on the report I made, "Round ELL", I added a calculation to add in item dimension list #4 and #5 which are the bottom and top extension for the 90 degree gored elbow. In this table you can see the center line length of the fitting with the extension is 12" longer then the other fitting, which is correct. The second table, "Center Line Length", is just pulling the "item center line length" with no calculation. In this table, it is showing the lengths are the same for both fittings even though I added a 12 inches of straight to the one fitting. This is also an issue with tee fittings where it only gives me the length of the main body and not the takeoff.

My question, is there a place where I can edit the "item center line length" to add in any top/bottom extension or takeoff length so I do not have to add in a calculation to the table? I currently need to make multiple tables because different fittings need only certain "Item dimension list #'s" added into the calculation.

Thank you for any help you can give.
