The help file describes the options
OrientOnCrv. I don’t see those appearing when I type the command or choose it from the “Transform” menu.
When I use the tool button I do see those options to click on, however the orientation of the object respective to the curve is different, and not as described in the help file.
Base point for the original object is 0,0,0.
About the help file text: following the video example, “Pick an angle or two reference points to rotate the curve.” should read “Pick an angle or two reference points to rotate the object around the curve.”
