Ooh… Let me see if I can clarify. Going to be difficult since it isn’t always a repeatable occurrance.
I have a line (Straight line, stroke doesn’t seem to be a factor, corner radius set to 10 pt). I select the node tool (or selection tool) and put over the place on the line I want to insert a node. Double click/tap. Most of the time, the new node is inserted in the correct place. However, some times it will be inserted on the other side of an adjacent node. Everything works after that. Only issue is where the new node is sometimes created.
Rounded corner radius of 10pt (works better than curved line for me)
Flexible Canvas (I love this!)
Grid displayed but no snap
Units are feet (difference from feet “’”?)
Canvas scale is 1 inch = 20 feet
Not sure about an example because it is so random. I just tried to recreate issue four times and it would not happen. File is still at 56MB with all the extra graphics I have in there.
I know this probably isn’t helpful. Wish I could get it to occur more often.
