Knife Tool With Back one Step

Right now in blender with the knife tool, if you make a mistake in your cuts, the only way to remedy it is by either canceling the cut, or going though with it then fixing it by hand. Happens to me all the time, I'm almost done making my selection then I slightly miss one vertex or something. It would be great if by pressing backspace or "x" you could go back one cut so you can fix things without redoing the whole thing.

Maybe:

  • Ctrl-Z : Cancelling the whole action
  • Backspace : Going back one step
Pascal

it should be non-modal with percentage snapping on edges.

I can propose even more - hold Alt to switch cursor mode to change any slice point location. So user been able to fix cut in two ways - redo progres step by step from last point or move and fix any point.

WHY ?

If user already set 10, 20 or any count of points and it need to fix something far from current last point. If it would be able to redo points user can redo all the points until it reaches the point it need to fix. But to do this is to loose working progres. What if it need to redo 10, 20 , or more points...

HOW? User hold Alt and now it able to press on any point and move it. Moved point would be reprojected onto mesh from current view.

Photoshop example. Image

cursor in capture not match lines because of different monitor resolutions and scaling ...

PS Maybe it should be not Alt and not " hold ". Maybe it can be some F key and toggle mode during cut.

Marking this as Done! Undo was implemented for the knife tool/operator a few versions ago.

  • <kbd>back space</kbd>: to delete last point. several points if press several times. currently if you miss a point you have to do all again
