Question:

Mechanical design is to draw the general plan or draw a part diagram first?

Force calculation is in the component diagram, the size of the component is obtained by force, and if you don't draw the parts first, how do you draw the general plan?How do you calculate the force of a part if you draw the part diagram first and don't know the size relation between the parts?

Answer:

I seem to have seen the online video in this class. Draw a sketch first. Forget it. I'll look for it
First draw a diagram, determine the location of each part, then draw the parts drawing, and finally the general drawing
Usually draw the general plan first, and then draw parts, parts drawing. This arrangement facilitates the arrangement of the overall layout of the designed device.For experienced designers, the key components are often designed first. Then the overall design is carried out around the key components.Experienced fitter often starts with parts.No matter where to start the design, the design process always emphasizes the function realization of the device, and then carries on the strength and the rigidity check. When the strength and stiffness are insufficient, return to the design origin and start the design again.
