Create section box align to diagonal duct

[yinodo2737]

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

Hello @yinodo2737 and welcome yes its possible…try take a look at this post here and share what you have tried so far, unlees its just a question

How to get help on the Dynamo forums

One of the main goals of the Dynamo community is to help others. One way to do that is by answering your questions. But to get the right answer, you’ll first have to ask your question in the right way. Although people are generally very helpful, there are things you can do to improve your chances of getting good and quick answers. Below you will find some suggestions on how to achieve that. Do not think of these suggestions as rules and especially do not take them as a guarantee of getting an an…

iam a nweb. i only know the basics get parameter, set parameter and these things
my thought process is to get the rotational angle of the duct then set rotation of the section ox but i don’t know how xD

try first with a boundingbox with miniun volume as a start

[jacob.small]

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 therein.

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

[yinodo2737]

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

[yinodo2737]

tried that. not sure if that’s what u meant

[sovitek]

Yeahhh try as here and see if it could work

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?

[yinodo2737]

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

[sovitek]

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

[c.poupin]

Hi,

we can also use ByMinimum.Volume

Section Box not creating

Here is a workaround, You may need to adapt the Python code to meet your requirements. [set_section_box_from_align_bbx] import clr clr.AddReference('ProtoGeometry') from Autodesk.DesignScript.Geometry import * # Import ToDSType(bool) extension method clr.AddReference("RevitNodes") import Revit clr.ImportExtensions(Revit.Elements) clr.ImportExtensions(Revit.GeometryConversion) # Import DocumentManager and TransactionManager clr.AddReference("RevitServices") import RevitServices from RevitSer…

@sovitek

View3D.SetSectionBox

ye thx it worked with python
was just wonder if its possible with nodes only just to learn

[sovitek]

Hi Ahmed
I am afraid not, if you mean OOTB nodes, but you could take the P node and create a costum DYF…it will probably be the closest…and btw its the same as View3D.SetSectionBox node as i think is from Clockwork, is written in Python as well, but just stored inside a Dyf as well…hope it make sense, for learning just try go to Primer, or/and follow in this forum here, and just practice so much you can..and then suddenly you will be an expert

PS youtube is great as well i like Aussie Bims videos, and Autodesk Office hour…as is good too IMO ;).
