    projection of points from a sketch to a sketch

    Hi there I would like to know if it is possible to project some points from a 2D sketch to a new 2D sketch (the are perpendicular located each other) or another way i could handle is to snap some circles to from one sketch to the points that are created in the first one. I assume that the...

    BLDC for outer space aplication

    Hey thanks so much for your answers I know some few stuff about this For example, i don't want speed reduction with gears, because it increases the chances of failure. About vacuum conditions and lubrication, well it should be dry contact, we should modify the bearings from metal to ceramic...

    BLDC for outer space aplication

    Hi IMCJOEK Yes. this is a small sat. It is my first project here and i have never chosen any electric motor before. in fact i just make thermal simulations, but now i need to make this device. I have done the next tasks: I selected the 1608 BH motor, i have plotted the next graphics Torque...
