Select divided surface by intersection

[mikael.santrolli]

I have a custom divided surface in revit done with intersections.
I now would like to import the surface do dynamo tu evaluate uv and nodes.
I’m unable to select the divided surface. How can I do it? Which node do i have to use?

Thanks

is it in a project or in a conceptual mass template?

Conceptual mass template

You can do it like this:
Make sure the nodes are displayed! otherwise dynamo won’t retrieve them.

here’s the code:

import clr
clr.AddReference('RevitAPI')
from Autodesk.Revit.DB import*

clr.AddReference('RevitServices')
from RevitServices.Persistence import DocumentManager

clr.AddReference('RevitNodes')
import Revit
clr.ImportExtensions(Revit.Elements)

doc = DocumentManager.Instance.CurrentDBDocument

pts = []

divsurf = FilteredElementCollector(doc).OfClass(DividedSurface)
s = [d.ToDSType(True) for d in divsurf]

OUT = s

Great! It works, thanks Mostafa!
I have another questione. How can I trim the surface with the curves to get the single shape of the panels?

Random list of lines (Voronoi import pattern): Can we sync them?

Hi Sol Amour, here’s an idea : you can extrude those segments, join all surfaces you get as a polysurface and then use it to split the base face. You will get your “cells” as surfaces and can then go back to their outline with surface.perimetercurves . This is more geometric than logic but it gets you there fast … [voronoi]

the onlly difference here is instead of using ZAxis to extrude you need to use some other vector… I don’t know exactly how your grid is created but maybe the normal to the surface at the midle point of each gridline could work…

Hello,

I have the same question but my divided surface is inside a project- not in the conceptual mass template, and the options for surface representations are disabled…

Appreciate any help.

You have an in place mass?

[sebastian_sepulveda]

yes it is an in place mass, from an updated 2014 model into 2017.

@sebastian_sepulveda if you show the surface you can display the nodes:

then an element.geometry node will get you the points. You’ll just need to filter them out :

Great! Thanks.
