I've nudged things a bit and got this: http://ivan.sanchezortega.es/lego/wheels_right3.lxf It's wrong anyway - if you center the camera on the axle for the black wheel and zoom in, you'll see that the axle is off-center even so slightly. If I nudge the pieces a tiny bit closer to correct that (by 0.01 mm), LDD thinks that the gears collide. Man, I hate floating point arithmetics. > Oh yes - and believe me, LDD guys are aware of that! So, can we have "LDD AFOL edition: now with 'turn the damn collisions off' button!" ?? :-) -- ---------------------------------- IvÃ¡n SÃ¡nchez Ortega -ivan-sanchezortega-es-
