Hi everyone, are there any of you have tried scripts that create a duct bank (multiple pipes at one network) similar to the image to an offset of an alignment? I’ve tried parts builder for pipes but have no luck achieving my goal. Now I’m looking into making Dynamo Scripts that can model duct bank (with the circles and square) pipe network. I’m new with Dynamo and any recommendation would be helpful, thanks in advance! 
Hi @KenD,
This is definitely doable. What would determine the pipe elevations? I am assuming the alignment would have a profile?
And if so, will you be dealing with combinations of horizontal + vertical curvature?
Hi @zachri.jensen,
yup! I’m planning to use the alignment profile and that would be the case. I’ll be dealing both horizontal and vertical curvature.
If this is the case, then the bulk of the work in Dynamo is going to be deciding how you want to tesselate the different types of segments in the alignment + profile combo. Pipes don’t support both horizontal and vertical curvature, so you’ll have to “chop up” the curves to approximate them with several small pipes. It might be easier to just do the same thing for the straight segments as well for simplicity.
If all you’re trying to get to is some type of 3D solid model for visualization and clash detection, then just using 3D solids will likely be easier than building a pipe network.
thank you for your great insight! thought of modeling them as 3D solids but since everything is still on design phase I thought of making dynamo script to make it dynamic and updates a lot easier.
You can still use Dynamo to generate 3D solids and update them dynamically. So the main question is if you need pipe objects down the road for some other purpose, or if the solids will suffice.
