View Full Version : Ductwork: 1 line & 2 line represented on the same drawing

Summary: Have the users input a "cut-off" size to represent 1 line duct to a certain size and then show 2 line duct for all sizes above that on the same drawing for all types of ductwork (rectangular, round, and oval).

Description: Right now ductwork can either be shown as 1 line or 2 line, you can not show both representations at the same time on one drawing. This is an issue. Once the ductwork gets down to a small size (say 8" dia for example) if you are using the 2 line representation the lines have a tendency to "bleed" together on the print. If you are using the 1 line representation it is difficult to have a visual on a large duct and often times it will misrepresent the amount of space that is remaining in that area. Therefore, leading to too many objects trying to occupy one space and creating interferences. This will lead to less interference issues in the field and easier to read plots for checking and construction.

How Used: This should be an option to allow the user to input a certain size to show 1 line ductwork up to and then automatically show 2 line ductwork above the user specified size. This would be for all kinds of ductwork: rectangular, round, and oval.

Feature Affinity: HVAC ductwork

I think this is a very doable one. I haven't use ABS yet, but I'd guess they would act just like the structural member style in ADT. You have a single line that represents the axis (centroid) of the member and another component that is the "body". Maybe someone else can also shed some light on this.
I like the idea.
