UNDO behavior between version years; undo within command vs end command

[Anonymous]

Has anyone else noticed that the UNDO command behaves differently in C3D 2017 than it does in 14 and 12?

The example that is making me crazy is with the polyline command, but its not limited to only that. Start drawing a polyline and set a few vertices, then hit CTRL+Z while inside the PL command. In 12 and 14 this would just trigger an internal undo within the polyline command and undo the last PI inserted until you got to the beginning point of the line where it would just get stuck until you hit escape and cancel the PL command (or start drawing again).

In 17, hitting CTRL+Z while insde the PL command will terminate the command and undo the line you have just drawn. You can type U and ENTER to step back one PI, but you have to hit U ENTER every time if you want to go back several, you cant just hit enter again to repeat last command (that just ends the PL command).

Am I the only person bothered by this...? 😞 anyone know how to put it back to the way it used to work?

I was given some advice by a coworker to check what was happening within the CUI for the UNDO command which led me to solving this!

The macro text for the UNDO entry was ^C^C_u, which is equivalent to hitting the escape key twice and then typing U on command line.  This by definition will break out of any active command.

So I switched to a different version of the UNDO shortcut where the macro was just _u, and now I can peel off PI's within the polyline command again!

edit: I hope its not bad form to mark my own solution as solved....but its been solved...
