FITLINE and FITARC?
In the release notes for 21.2.03 we find FITLINE and FITARC: "These two new tools will create a line, or a circle/arc, through a set of input data points." Those commands would be quite handy when trying to fit a drawing object to a scanned image or picture. If they're there, though, it's not clear how to invoke them. The command line returns "unable to recognize command." Nothing in the online help, either.
