1. According to design requirements and the actual use of drawing the Manifold four sides and the top surface view.
2. According to the layout of the production process layers pore draw layers cutaway view, easy to understand and production principle.
3. For the processing of convenience, each hole numbered list, and indicate the aperture, hole depth, and connected with an empty number.
4. Draw manifold assembly appearances, the shape of the manifold valve installation diagram shows the position and orientation of the valve installation and confirm the size and requirements.
5. Dimension can come to the basal plane type , the coordinates of two sizes marked a method . More complex structure of the manifold block should coordinate type, that is, choose a corner of the block (usually in the lower left corner of the main view ) as the origin of coordinates , the center coordinates of each hole coordinates marked its mounting surfaces only the standard of the coordinate method baseline position of the screw holes , and the rest of the size of the base screw holes marked as a benchmark . In this way , not only facilitate the achievement of the CAD, CAM, they will be hand- drawing, paste component model pattern ( selected components , according to product samples to draw it to the top view and outline of the bottom erosion outlet location size of the pattern ) and pore location.
