I have multiple families, each family is a swept geometry and each has a curve/rail to sweep along in the editor. Is there anyway I could access this curve geometry using Dynamo? Any help would be great, thanks!

Could this thread help to get started? [image] How to get the length of a Model In Place sweep? Revit If anyone can help!. I’ve spend an all day trying to get the lenght of an in-place model roof, in this case is a roof fascia. The main problem is that this roof is a in …

Hmm, it doesn’t seem to be returning any results…this is the hierarchy to access the sketch for me: Edit Family > Edit Sweep > Path : Sketch Should your attached process be working for this case, or am I screwing something up? [Collector Empty]

Have you tried clockwork’s Element.Location node?

Hi @Tom_James , thanks for the reply, however I’m still getting no results for any curves, this has got me stumped! [image]

Could you share one of the families? It looks like it is point based from your image. The output from the ‘IsCurve’ should return true if it is curve based, but it looks like it will return true for the ‘isPoint’ output

Hi @Nick_Boyts , thank you for the reply, however it’s now becoming obvious with your suggestion that @Tom_James may be correct with this being Point based (see below results). Not sure what this means for me collecting the actual curve though, because there is a curve for the sweep in the sweep edit…

Ah, I missed that comment. I almost made it myself in fact. You are correct in that if your family is point based the only “placement” geometry Revit has is the origin point of the family.

Ok, so the idea was that if the family was placed based on its sweep curve we could access it, but because it was not we won’t be able to access that embedded geometry?

Correct. It seems you can only get the placement or origin geometry. In a point-based family that’s obviously the origin point of the family. For a two-point or line-based family that’s the reference line that drives the geometry.
