Hi All, Thanks for your input about this problem. I think of them all, Shadowdragonlord is on to something. Ever since I discovered the ability to use "object space" aand "world space", I have made use of these features to aid in modeling. Additionally, I discovered that in the Attributes menu, I can click on the title "Absolute Coordinates" and choose from Absolute, Set as Unity and Remove Shear. These options are great for removing multiple angles and resetting them to zero. I did not know this was possible (the title is grey, seeming to indicate that it is not a setable feature) until I accidently clciked on it one day. This probably is confusing Bryce, so that when it copies a matrix, it doesn't quite know what to do about the angle, so it just let's that one go. At least, that's my theory. Anyway, thanks for sharing your ideas!
