Rebuild preview not working

Hi V5,
is this just me ?
I have curvature graph on, I alter rebuild values, click preview and nothing changes, click ok then massive changes , I have overdone it, so undo and try for different values, but I wish to preview see effects on graph, change a value , preview again etc etc.

I keep coming across this problem with rebuild. Preview inoperative, certainly if Curvature Graph is on.


Hi Steve please send a curve or surface and the values you are using to rebuild. Most likely the complexity of the surfaces or curves is above the cap where we draw the preview- this has been a bone of contention in one way or another for a while.
