i have a ducts with random angles is there a way to align the section box 3d view to that duct using dynamo instead of manual rotating which will not be accurate

Yeahhh try as here and see if it could work [Revit_aZhwMGcUhc] TEST.dyn (9.5 KB)

Hello @yinodo2737 and welcome :wink: yes its possible…try take a look at this post here and share what you have tried so far, unlees its just a question :wink: [image] How to get help on the Dynamo forums FAQ One of the main goals of the Dynamo community is to…

try first with a boundingbox with miniun volume as a start

You could try pulling the geometry, getting the bounding box by minimum volume, extract the coordinate system and dimensions from that, and use those values to generate a bounding box in Revit, which could finally be used in a View3D.SetSectionBox method; however I don’t know if there are limits the…

may you please provide a graph if you are free as iam a complete beginner

i tried that by the help of ChatGPT but couldn’t find the node that would create the bounding box by coordinates

[image] tried that. not sure if that’s what u meant

[image] yinodo2737: i tried that by the help of ChatGPT Instead of a generic AI built for general purpose stuff you’ll want to use something focused on Dynamo use. Have you considered registering for this alpha offering?

Thanks it worked flawlessly just askingis there a way to do it with nodes only?

yeah a longer way…but not sure we have a View3D.SetSectionBox as ootb anyway as i guess will be the critical one :wink: but havent tried
