Hello, I'm trying to construct a spiral ramp using mass tools— basically extruding a section profile along a series of arcs as shown in screenshot 1. I've semi-successfully generated the form, but it's skewed at the base of the ramp, as shown in screenshot 2...
For some reason I cannot select the profile at the base of the ramp, and rotate back into place. I was wondering if there is a way to keep the profile vertical, relative to the project? Maybe by tweaking the reference point properties (screenshot 3)? Any thoughts are appreciated! Hope this hasn't already been covered somewhere.
Thanks very much,
kyle

Well, I know exactly what you are going through and there is no easy solution. If the construct is a ramp, I would much rather struggle to make it work using the Revit Ramp tool rather than a Mass Form -- which in and of itself, has no BIM value in the end.
how I'd do it:

...you could even build it as a Floor (shown below)or a Roof, as well as a Ramp (shown previously).
You can also add a few profiles on the work plane of the points along the path, then select all the profiles together with the path to create the ramp.
