Confusion using 'Undo'

Post by rgsheehan » Tue Feb 15, 2022 5:15 pm

If I draw a line segment, then another one continuing from the first, and then press Undo, the second line is removed, but the 'little red circle with the cross' does not go back to the end of the first line segment. If I want to continue from that point, how do I get back there (precisely)?
Thanks in advance,
rgsheehan

You can move the relative zero point any time:
Snap > Set Relative Zero

Andrew, is it intended behavior for the relative zero point indicator to stay even if the user undoes the step that was responsible for placing it there like mentioned above?

Yes. The relative zero point is not part of the transactions which are used for undo / redo.

Hello again,
Thanks for the quick response.

In the interests of 'precision', given let's say a series of relative polar coordinate steps, and then the aforementioned undo, how does one get back to the -exact- location of the previous end?

Sorry for the newbie type questions, but that is kind of where I am at.

You would use Snap > Set Relative Zero. While setting the location of the relative zero point, you can use snap functions as usual, for example to snap the end point of the previously drawn line.
