This might be something I’m doing wrong, or getting confused about orientation, but I’ve thought it through and I can’t see where I’m going wrong.
The modelling I’m doing at present involves creating accurate polylines, using 3D-co-ordinates with the Y co-ordinate set to zero, then rotating the shape around the z-axis. On about four or five occasions over the past three weeks, I put in a co-ordinate of the next point, say 3, 0, 21 and instead of the point appearing on front view as 21 “up”, in fact it shows as 21 on the Y-axis. For the remainder of the polyline, I have to use X, Z, Y co-ordinates, for example, 3, 21, 0 to get the shape I want. As long as it works, and doesn’t cause problems in downstream printing, this is annoying but not a show-stopper.
I don’t have a reproduction scenario yet, but I think the cases where it has occurred I think I will have recently done “Undo” on the polyline wizard and/or Esc-aping (cancelling) the poyline wizard to start again where I realised an earlier point had been entered incorrectly.
Can you think of an explanation for this or should I keep looking out for a reproduction?
