I have rivet circles brought in from photogrammetry, those on the lower parts of the fuselage are as expected leaning inwards as they disappear under the body.
In perspective view how can I copy my Rhino drawn planar upright circle (XYplane) to those and make it take on their planar angle ?
For most on the sides I havent bothered for what is needed.
Once they are in position I need to project to skin so I would get a very eliptical circle after the projection for the lower ones. They will cease to be perfect circles anyway.
I am not going to create a Cplane for each rivet angle either !
