I’m having issues on Safari too – I had to reload the page numerous times before I could watch it.
A bit offtopic, but when I upload a video to Dropbox and copy the link here, it is going to display an empty video box which won’t play, so I have to insert the URL as a hyperlink (like this) to make sure it can be accessed. (Usually my screen captures are way too big to fit the file limit here.)
I set this to 40.52 degrees because that is what the rectangular geometry is rotated from x,y being left right and up down. I thought that this is what I should edit rather than rotating the CPlane.
I put 90° in here and also in the OrthoAngle box and it NOW WORKS PERFECT!!! Lines now track on x,y at 90° from one another. What a relief!
Your help has been wonderful. I sincerely appreciate it! Below is a shot of it working perfectly.
Glad you got it worked out. One other thing you might want to look at is Universal CPlanes vs Standard CPlanes (set in Options>Modeling Aids). with Universal CPlanes set, if you set a custom CPlane in the Perspective viewport to align with your model, the other views - Front, Top, Right, etc. will automatically align to that plane, giving you true views of the object. Takes some getting used to, but might be useful for you in this case.
