I've been doing a lot of work lately in building as many Technic models in MLCAD as I can. I find the lack of the following list of wheels and tires the most vexing. If anyone wanted to put them on a "most wanted" list, that would be great! * 41896: (...) (15 years ago, 18-Jun-09, to lugnet.cad)

Hi Kevin, Here's the problem. A mirror plus a rotation can look just like a mirror across another axis. Ugly 2D ASCII art example: .|b --- .|. Mirror the b to the left. d|. --- .|. Rotate 180 degrees. .|. --- .|p That looks just like you mirrored (...) (15 years ago, 15-Jun-09, to lugnet.cad)
