Aspect ratio error never mind what I try

Hi,

Trying to add a plain cylindrical (i.e. not conical) target.

I started off using real object dimensions but I kept on getting aspect ratio errors when trying to upload the side image.

The image is 2693x827 resolution.

This gives me the aspect ratio of: 2693 / 827 = 3.25634825

I resulted in using the pixel coordinates just to see what it would complain off as there is then less calculations that might cause rounding errors, etc maybe.

With the above mentioned image resolution, I get my top and bottom diameter:

w = 2693 / pi = 857.2085 (this is using the full value of pi and not just 3.14 as stated in some of the online documentation. Also the editor only allows 4 decimals to be added)

h = sL = 827

I use those values and create an cylindrical image target with top and bottom having the same diameter w.

When I upload this said image as the side image, I get an error saying my aspect ratio should be 3.256.

I;ve tried 'gaming' the values to make it fit into that aspect ratio, but keep on chasing my own tail as I keep on getting aspect ratio errors with different values, thus never being able to hone in on a matching golden equation that will make it work.

(also if I click "Learn More" in the error message, Chrome gives an error page complaining about too many redirects) 

Help would be appreciated.

Cheers!
