Abstract
Most appearance and structure design has always been based on the product processing technology as the spindle, in general; sheet metal design changes in the appearance of the structure is based mainly on the basic structure of products and processing technology as the main core, and the appearance of manufacturing more Mechanical sheet metal, so most designers will use different design procedures to draw 3D graphics in the assembly or disassembly of parts, but different drawing procedures will affect the future assembly and disassembly of the design. In this study, we will compare two different models by building a model program using two different sheet metal structure drawings to present the problems that may be encountered in sheet metal design through a specific design flow. Through a real 3D drawing and design case, 3D graphics design flow, and finally through a design case to do a verification, to provide a reference for the future design.

IntroductionIf the same customer needs to reduce costs, the product must have a certain similarity, must be little change, often only a small number of holes or the main dimensions need to be modified , If you want to re-disassemble the parts or 3D surface redesign, it is easy to waste time, and the process is prone to design errors, just as "At the present time CAD is not a suitable tool for engineers
Most mechanical sheet metal designs are based on the customer's design surface or 3D model as a design basis, and through the R & D department or designer for part assembly or 3D parts rebuild, and to meet the processing Factory processing, and designer identification
In this part of the experiment, we want to explore the difference between synchronous modeling and order modeling when starting sheet metal design
Summary
If the same customer needs to reduce costs, the product must have a certain similarity, must be little change, often only a small number of holes or the main dimensions need to be modified , If you want to re-disassemble the parts or 3D surface redesign, it is easy to waste time, and the process is prone to design errors, just as "At the present time CAD is not a suitable tool for engineers. Engineers need an easy-to-use 3D tool tailored for conceptual design but usually they communicate concepts through 2D sketching or presentation tools and a CAD operator has to interpret their wishes in a specific modeling tool. This way is easy to commit errors and lose time often resulting in not substantially achieved engineer effectively wanted ". How to provide a good way of drawing is a topic worth discussing
