Got a question on making a reference plane that will show the pipe normal to screen in view such as in 4th pic below. I get pipes frequently with irregular cuts and need to be able to show them on a drawing for sawing and/or handburning. I always seem to have an issue trying to get the view oriented properly (I can drag the view onto drawing then use rotate for the view, but when I pull some dimensions they never seem to be in the correct plane i.e. horiz. and vertical they are diagonals since I used "rotate view"). I would like to create a plane such as plane1 where it is parallel to temporary axis (you can see it is sloped upward but I only chose the uppermost quadrant point on elliptical cut side). If I select the point on the opposite side, I get an error. See 3rd pic. Thanks in advance for any help on what I'm doing wrong. There must be a way to get my plane parallel. I've attached the file as well (its an "insert part" file from parent part so hopefully it can still be opened).
