When design machine parts<\/a> \/ prototypes<\/a> by 2D engineering method, we can adopt simplified drawing method:<\/p>\n\n\n\n

1.When the object (mechanical part<\/strong>) has several identical structures (teeth, slots, etc.) and distributes according to certain rules, only a few complete structures need to be drawn. The rest are connected by fine lines, and the total number of structures is indicated.<\/h2>\n\n\n\n

2.A number of holes with the same diameter and regular distribution (round holes, screw holes, sinks, etc.) can be drawn only one or several, the rest can only be represented by the center line, and the total number of holes should be indicated when the size of holes is marked in the figure.<\/h2>\n\n\n\n

3.The reticulated and knitted parts of nets, knitted fabrics or objects can be drawn by means of fine lines near the contour lines, and the specific requirements of these structures can be indicated on the drawings or technical requirements.<\/h2>\n\n\n\n

4.When the graphics can not fully express the plane, they can be represented by plane symbols (two intersecting solid lines).<\/h2>\n\n\n\n

5.Small structures on objects can be simplified or omitted if they are clearly expressed in one figure. Two small circles are omitted from the main view and the intersection line is simplified from the top view.<\/h2>\n\n\n\n

6.In the absence of misunderstanding, small rounded corners on objects, small chamfered edges or small chamfered corners of 45 degrees on sharp edges may be omitted without drawing, but they must be specified in size or specified in technical requirements.<\/h2>\n\n\n\n

8.A circle or arc with an inclination less than or equal to 30 degrees from the projection surface can be replaced by a circle or arc.<\/h2>\n\n\n\n

9.When the shapes of long objects (axes, rods, profiles, connecting rods, etc.) along the length direction are consistent or vary according to certain rules, they can be shortened and drawn after disconnection, but the dimensions are still marked according to the actual length.<\/h2>\n\n\n\n
