Hi,
I think when you create drawings for tubes and pipes it would useful to include the "Bend machine output" data that can be taken from an inventor tube and pipe model. This data is either the XYZ points of the tube/pipe or the LRA data.
This data could be added to the tube/pipe drawing in the form of a table in the same way bend tables are added to sheet metal drawings. This way updates to the tube/pipe would automatically update the drawing.
Currently if you want this data in the drawing you export it from the tube/pipe assembly to another file. Then copy paste it into a general table in the drawing. So any revision to the tube/pipe won't update the table in the drawing, then you have to export+copy+paste the updated data into the drawing.
