Thanks for the responses--they were very helpful. I found the disadvantage to
Don's rotation matrix method to be that when it's used the mouse commands in
MLCad are reversed, i.e., dragging the part left moves it right--but it sure
worked great for a quick way to show the assembled model correctly.
Dave, I tried your method in Excel and it appears to work with some caveats,
though I don't really understand the column mappings:
For left-to-right, you said to use columns D and G--that's corresponding to the
Y position and the B rotation parameter. Shouldn't that be the X position and C
parameter?
Parts such as slopes & 2 x 2 corners aren't in their correct orientation--any
tips on how to get those right?
(Actually, is there a tutorial on the rotation matrix anywhere? That might
answer all my questions in one.)
Thanks!
Carl
