I am trying to create a sweep based on a non-planar spline through points as an in-place mass, however it gives an error of self-intersecting geometry. Is there a way to counteract this?
I have already tried splitting the spline. Could there be a way to create it from an adaptive family that bends on hosting to reference points of my spline? The sweep profile itself can be a rectangle, as long as it transitions from a 3 meter width to a 5 meter width as indicated by the profiles in the attachment.
It looks like you are trying to do a kind of sweep blend. Are both those profiles shown being used in the same form? If so, I cannot imagine how that would work. The profiles appear to being on opposite facing workplanes. Can you elaborate on what you're trying to do? Maybe post the file?
Sorry, my bad, it was done on purpose. The image with the self intersecting geometry shows how the sweep works when I use a single 3m wide line (as substitution for both profiles). It basically crosses over from the left hand side of the spline to the right hand side and gives an error when I use a profile to sweep to begin with.
So to clarify: the question is how to control the sweep in such a way that the profile remains on the left hand side? The curve itself is more of a S-shape (seen from top) and a C-curve (from the sides) hence why Revit has trouble identifying the location of the swept profile.
It is supposed to become a path alongside an elliptical building, attached is a rough image in 3D as well as the mass in a clean project.
