is it the first overall drawing, or first out parts drawings, and then assembly?
Personal habits ~ ~ general circumstances, the first overall map, and then parts map ~!
Personal habits, I love the first overall chart, so they have a grasp of the overall design, in the design process, the first part drawing will lead to late in the assembly process of interference, size deviation and other issues.
Take out the part drawings first and then assemble them into a whole picture
