I’ve been meaning to report this more than a few times, but never got around to it (or maybe I did report it and just forgot?). If an object has shut lines enabled, it seems as if they are recalculated every time the obejct has been hidden away, and not only once, but twice, if you use
ShowSelected: recalcute for selecting the objects to show and recalculate for actually showing the object.
When working with complex geometry and fine render meshes, this can take a while (to say the least, especially if combined with displacement!!! ), so would it be possible to keep the rendermesh intact when hiding an object with shut lines? By the way: it also recalculates objects with shut lines if an object WITHOUT shutlines is hidden and you then use
ShowSelected to unhide other objects - although it “only” happens once, as the command is completed (after selecting which object(s) to show). This goes for both V6 and V7 WIP.
Could this please be tuned up - it seems like a waste of computing time. Also, it seems that none of the other “modifiers” - curve piping, thickness, edge softening, displacement - suffer from this bug. Or maybe it’s just my system being really weird?
