I am trying to place a family along an Autocad import. It seems like it will kinda work on some curves but not others. The ones that kinda work will align in X and Y, not Z. The goal is to place all families aligned to the autocad curve.
I have been through a few of these forums:
http://dynamobim.org/forums/topic/align-objects-with-a-3d-curve/
http://dynamobim.org/forums/topic/rotate-generic-family-with-dynamo/
It appears I am still missing something. Thanks in advance.
I have done this with segmental tunnel models i.e where you place a precast rings along a path.
The workflow is:
divide the path e.g 3D polyline at required distances
export the coordinates of the points using ACAD data extraction tools or Civil3D *
feed in the coordinates to Dynamo Revit- as Vikram says using a 2 point adaptive family
Civil3D is better than vanilla CAD for dealing with points- particularly exporting data and working with coordinate systems

Thanks for the post Andrew. I will give that a try. I initially wanted to stay away from an adaptive family, but it might be easier.
I also received a Rhino file of the same curves. I may try and create one rhino file for each curve, then import. I have seen a few posts on this as well.
Thanks again,
@Mitch_Condie Try replacing Vector.AngleWithVector with Vector.AngleAboutAxis
In the example below, doing so solves the issue.
