I’m having a poke around to see if I can dig up any other differences between the V7 and v6 version of the same panel. Trying to spot other differences.
Looking carefully at the polylines for the V6 unrollsrf vs the V7 unrollsrf in the drawing above. They are within the same drawing … not superimposed.
Can also see some differences between the segments of the V7 bottom … it looks like the isolines have been set up equidistant within each section (bordered by the darker transverse lines breaking the panel into 5.
… whereas in the v6 generated flat panel the isolines are spaced more like what I would expect, something like a geometric progression with more concentrated curvature between the sections. I wonder if there is some curvature approximation (or averaging) going on in V7 which then forces the knots to happen.
Also a difference if I Explode the panels … remember these are both in the same V7 drawing now.
V7 splits into different segments.
V6 can’t be exploded. Stays in one piece.
Hoping someone can see why unrollsrf created with V7 is behaving so differently.
