< As I understood from an older post of mine, moving the solid breaks the connection with the curve that created the solid and there is no update.
I can't understand why it doesn't work now...
Indeed : that's the perfect example of a" breaking History" (named "Dynamic Geometry" in another prog)
You must don't move any solid from it constructor curves or makes any move of volume + constructor!
It's the hard rule: all must stay in place :)
But if you make that : select all the constructor first and move it, all moves with it and you don't lost the history :)

For the fun you can try that
On view Top draw a circle, on View Font draw a simple profil line
Call the Rail Revolve, Select the profil, clic the circle as rail
Now you can move alone the profil or circle and don't lost the history
if you call Show Points for modify the profil or circle :)
But don't move the "surface" !!! else History will be losted!
