How to draw the body of mechanical drawing?
Sheet LagoutIn the drawings, the frame line must be used to draw the solid line, the format is divided into left and left edge binding binding edge of two, but the same product can only use a format pattern.title barGB/T10609.1-89 on the title bar of the content, format and size of the provisions, the title bar text direction should look direction, the title bar of the frame is a solid line, there are fine lines, the right line and the bottom line should coincide with the frame line.
Draw the distance from the top view of the 45 degrees on the extension, straight to the main view of the corresponding surface.Just guarantee a tolerance of 45 degrees.
The projected line below the angle of the icon is not the sizeThe next 45 degrees that angle, where directly pull up on it
When drawing, this distance should be extended from the 45 degree view of the top view line to the counterpart of the main view. There is no need to use the size, just guarantee the tolerance of 45 degrees. If the angle tolerance is marked, the size will be contradictory. Of course, you can use the trigonometric function to figure out the size.
Give priority to the use of a standard mechanical drawing: a drawing mainly includes: A0 (1189mm * 841mm) and A1 (841mm * 594mm) and A2 (594mm * 420mm) and A3 (420mm * 297mm) and A4 (297mm * 210mm) and A5 (210mm * 148mm) 11 specifications.When necessary, the B class and C class of the extended format are also allowed to be used, and the size of the extended format is increased by an integral number of short edges of the basic format.
