(...) Yes, this is part of the plan. (...) LPub has to consider the rotation matrix for each submodel. If the rotation matrix includes negative numbers, then we're talking about mirror images which should not be put together in one callout. (...) (16 years ago, 27-Jun-08, to lugnet.cad)

(...) Actually, the matrix can have negative coefficients without being a mirror. If I remember correctly, mirror detection is a matter of checking if the determinant of the matrix is positive or negative. If the determinant is negative, then the (...) (16 years ago, 28-Jun-08, to lugnet.cad)

(...) You remember correctly. A 90 or 270 degree rotation will have a negative and positive coefficient off the diagonal while a 180 will have two negatives on the diagonal. Tim (16 years ago, 28-Jun-08, to lugnet.cad)
