I have attached a photo with some explanation on it hoping that it will explain better than my words do .
I inserted a usual weldment cut list table into my drawing. I customized it so it gives me the total length of every profile in the last column.
Usually, it gives me the same number for all the items that have the same profile
In this case, it gave me two different numbers
I checked the part, and all these structures have the exact same profile
I do not know why did SolidWorks consider them two different types
Thank you very much
