In 2018 and previous versions, one could associate (compound profile) both the profile, and the 3D spline with a sweep. Thus allowing size of profile and node positions of spline to be altered. And the sweep would be updated.
Well. in 2020 (and 2019), IMSI seemed to have deliberately broken the tool. So that only the profile can be associated. I say 'deliberate' as there is now a pop up a message saying it cannot be done. What is silly, is that if the profile and spline are associated with a sweep in 2018. Then saved and opened in 2020 the association remains fully functional. so its not a limitation of the tool.
Anyone know if it is My Error. And they have just changed how the compound profile association is accomplished. Or if not, have a reason why it was broken. Or If IMSI were informed (beta forum) that they broke something that was working fine.
