Layering principles and methods of standard structural parts graphic structure 5.1 Layering principles
The layering of standard structural parts graphic structure should be conducive to the management of graphic library; it is conducive to the drawing of electronic product drawings and the extraction of data.
5.2 Layering methods
The standard structural parts graphic structure contains many graphic elements with different properties. According to the layering principles, these graphic elements are stored in different layers of the graphic library. For example: a
Screws, self-tapping screws, wood screws and bolts can be layered according to the head and screw parts; washers can be layered according to the outer contour and inner hole; welding pieces can be layered according to the fixing holes and other graphics, and the attributes can be layered according to the name, standard code, model specification.
