I have two coordinate systems (xyz and x'y'z') and I need to find the angle of rotation between the two of them. xyz is fixed and x'y'z' starts in the same position as xyz. x'y'z' is then rotated 45 degrees about the y' axis and then rotated 30 degrees about the z' axis.
After the first rotation it's not bad since y and y' are still inline, but when the second rotation is made I get completely lost. Is there some trick for figuring out something like this? Thanks
I'll try to expand on what I'm asking for since some of the comments posed good questions. Also what I'm trying to do is take some 3D CAD into a simulation software and I need the relation between the mounting point and the end of the tool, which is rotated in two directions. I can't figure a way to measure this in my CAD world or I wouldn't be here.
I would like the x, y, and z angles between the two coordinate systems. Below are some pictures showing what I'm trying to do and hopefully it'll help.
The first picture is where x'y'z' (shown) is the same as xyz. The second picture is the 45° rotation about y' and the last picture shows the 30° rotation about z'.
I can move the coordinate system in my simulation program around and I get the values 26.733° about x, 37.653° about y, and 39.505° about z. Those values should be really close, but I cannot manually move that UCS exactly where it needs to be.
