(...) Not sure if this helps but... If you solve (M11+1) x + M12 y = - M13 M21 x + (M22+1) y = - M23 and then normalise the vector (x,y,1) the result will be a vector normal to the mirroring plane. To test that you indeed have a rotation/mirror you (...) (17 years ago, 15-Jun-09, to lugnet.cad)

(...) Awesome! Thanks, Mathew!! That's exactly what I wanted to see. I think what I'm building is shaping up to be quite similar, although I'm waiting on parts from the UK. Those darn 1x1x2 corner window pieces are hard to get now. I had to order (...) (17 years ago, 15-Jun-09, to lugnet.trains)

(This should probably have been in lugnet.cad.dev, and I almost put it there, but decided that it wouldn't make much difference.) I don't know the answer to this question. I'm responding any, just to let you know that I did read the question, since (...) (17 years ago, 15-Jun-09, to lugnet.cad)
