While tracing a tree image using splines for a school project i have run into some problems...I am creating a pattern for a plasma cutter.
When i move the points of my spline sometimes it causes the whole spline to randomly move around and twist and turn where there are no points. Also sometimes when i open the drawing some of the spline lines are out of place while the spline points have not moved.I have tried to constrain all the points but it turned into a mess.
How can i stop this from happening or is there a better way to do this?
