Polysurface Perimeter Curves (not expected result)

[ZJRODGERS]

Hey everyone, So i created a poly surface and i now what to get the curves of the poly surface and its giving me the uncombined surface geometry. What am i doing wrong? the surface should only have the perimeter lines.

Hi @ZJRODGERS

Try using the node Surface.ByUnion instead of the PolySurface.ByJoinedSurfaces node

[ZJRODGERS]

hey Daan, Thanks for the response! what package has the surface by union?

[Daan]

It should be OOTB, what version of Dynamo are you using?
( This node was added into Dynamo 2.3 )

@Daan ahh… im still on 2.0.4. Is 2.3 available for revit 2019?

[Daan]

I don’t know, i am using 2020 exclusively

[ZJRODGERS]

well… looks like i need to start using 2020. upgrade timeee… let me know if you have a solution around upgrading! thanks for the response though!

found a work around. Just extrude curves as solid then solid union. and then filter by the surface you want.
