Hi niko,

> ....when trying to move points on a curve

With which command, the Move command? Or by some other method like dragging the points without starting a command?

Also which view are you in when you notice this behavior, is it the 3D view? Do you see a different behavior in ortho views?

You may be running into some suppression of "on" object snap when in the 3D view which is described in this previous post:

I guess that may be getting applied to the Move command when it probably shouldn't, since move is not so much a planar-ized command like Rotate, although it does behave in a semi-planar way when you pick in the ortho views, which may be why it is getting categorized in that way.


Also when are you creating the construction lines, do you create them inside of the Move command? Knowing a few more details about exactly what steps you do may help me to understand.
