Re: Going from AC3D to .stl
Quote:
The unit conversion is 100 micron = 1 small square in AC3D. Which makes one big square a millimeter. However, working in that large of a scale is kind of impractical, the ReplicatorG software (the stuff that runs Makerbot) has a scale option built into it. I model mine at 1 small square = 1mm, 1 big square = 1 cm, and then when I import the stl into ReplicatorG I simply scale it all up by a factor of 10 to get a piece it likes. One other thing to watch out for, stl format likes to lay things on their side. As in, any normal mesh you open with practically any program loads rightside up, the stl rotates it 90 degrees on the Z axis. I've attached an image of a piece I'm printing out right now. The small one is the one I modelled in AC3D, the big one is the same one after I've rotated and scaled it properly in ReplicatorG for it to print the way I wanted.
