The hydraulic elements are simple and simple when drawing the hydraulic system
The two dimensional hydraulic, the electron and so on, but the three dimensional is not yet seen.
How do you develop a two-dimensional gallery that is a simplified picture of a standard part? 3 d is actually aid Output is the final request plan, some under the 3 d is not convenient to draw something, on 2 d supplements. I suspect that even if the parts were developed, in three dimensions, the average machine might not be able to run.
Would you please send a 2 d drawings (simple), we also try to see if I can give you a simple ideas build three-dimensional gallery...
