I included a picture. This was going to be my start of creating a library. One channel, where the length is tied to the part. I could open the channel, save as a new part, create an assembly with 3 channels, some tube, etc. I would change the length of the channels in the process of designing. When I create a drawing, I would like to insert a Bill of Material that is fully populated with the information, including the current length of the channel. Is there a way to incorporate the length into the properties, where it updates automatically when the channel is changed?
