I would like to ask you guys what are the specific steps to make three views?
The necessary condition is to learn mechanical drawing.
1. Method of drawing three views of a composite. Before drawing three views of a composite, first use shape analysis to decompose the composite into several shapes, determine their combination form, and determine whether the adjoining surfaces between the shapes are in special positions of coplanarity, tangency, and intersection.; Then draw three views of the shape one by one ; Finally, projection analysis is performed on the vertical surfaces, general position surfaces, and surfaces and lines in the composite that are coplanar, tangent, or intersecting. When incomplete shapes, combined columns or composite shapes intersect in the combination, the original shape restoration method can be used for analysis. 1. Carry out shape analysis to decompose the combination into several shapes, and determine their combination form and the mutual position between adjacent surfaces. 2. Determine the main view. Among the three views, the main view is the most important view. (1) Determine the placement location To determine the main projection direction, first solve the placement problem. The placement of the assembly should be chosen based on the principle of being natural and stable. And make the surface of the assembly as parallel or perpendicular to the projection surface as possible. (2) Determine the main view projection direction and choose the direction that best reflects the physical characteristics of the assembly and the mutual positions of the basic bodies, and can reduce the dotted lines on the top and left views, as the main view projection direction. The direction pointed by the arrow in Figure 9-10(a) is the selected projection direction of the front view. 3. Choose a ratio. When deciding on a drawing, try to use a 1:1 ratio. This makes it easy to directly estimate the size of the assembly and draw pictures. According to the selected proportion, predict the area occupied by the three views based on the length, width, and height of the combination, and leave a dimensioned position and appropriate spacing between the views, and select an appropriate standard frame accordingly. 4. Lay out the drawing and draw the baseline. First fix the drawing, and then draw the baseline of each view. The specific position of each view on the drawing is determined. The datum line refers to the datum for measuring dimensions when drawing. Each view needs to determine datum lines in two directions. Generally, the symmetrical center line, axis and larger plane are used as the baseline to draw the three views of each form one by one. According to the projection rules of each form, draw the three views of the form one by one. The order of drawing shapes: Generally, it is first solid (solid form) and then empty (excavated form). ; First big (big body) and then small (small body) ; Draw the outline first, then the details. When drawing each form, the three views should be connected and drawn, starting from the view that reflects the characteristics of the form, and then drawing the other two views according to the projection rules. Symmetrical figures, semicircles and arcs larger than a semicircle must draw symmetrical center lines, and the axis of rotation must be drawn. The centerline and axis of symmetry are drawn with thin dotted lines. As shown in Figure 9-11(b)(e). 6. Check, trace, and finally comprehensively check the manuscript. After finishing the drawing, carefully check each shape according to the shape. Vertical surfaces, general position surfaces in the form, and surfaces and lines where the adjoining surfaces between the forms are tangent, coplanar or intersect in special positions will be focused on checking using the projection rules of surfaces and lines to correct errors and supplement omissions. Draw depth according to standard drawing lines, with visible parts drawn with thick solid lines and invisible parts drawn with dotted lines. After tracing, perform another inspection to find not only clerical errors during tracing, but also errors before tracing.
If you know what "three views" are and can use CAD to draw two-dimensional drawings, your problem will be very simple. <Mechanical Drawing> will teach you what "three views" are. :)
No one understands what I mean. Talked so much nonsense. What I mean is that after drawing the three-dimensional diagram, three views are automatically generated. . . . Has anyone actually practiced it? Please don’t type a lot of words and say things that are not practical! Thank you! ! !
You are so arrogant. I suggest you pay attention to your tone in the future. Who would tell you if you speak like this? But in order to contribute something to the forum, I will tell you. It's actually very simple: 1. First draw your assembly, then go to View - Viewport - Three Viewports (depend on your choice, if you need to add an isometric view in addition to the three views, choose 4 viewports) and then you can see that the three viewports are the same, it doesn't matter, each viewport can be rotated in three dimensions, you can adjust them to the position of the three views, then it will be OK, then convert to two dimensions, and then print. It's that simple.
learn first* Learn some basic knowledge of CAD, otherwise you won’t understand anything you say. http://www.51zxw.net/study.asp?vip=16480 There are AUtocad video tutorials, which cover basic knowledge. Let’s take a look at them first.
First of all, you need to be familiar with mechanical drawing and CAD. First draw a 3D view, then select 4 viewports in the viewport item in the view, then click the mouse on the upper left corner viewport, and then select the main view in the 3D view in the view to define the top view and left view.
I suggest you spend some time learning* Use the view tool, let alone three views, whatever you want will do.
:lol Thank you! The 6th floor has a lot of opinions on me. hehe! I will pay attention to it in the future!
It is not difficult to learn mechanical drawing, but you also need to make full use of the functions of 2007
