The other parameters of the hexagon Blood collection mould Suppliers are automatically determined. It only provides interactive drawing functions.In the assembly drawing of the punching die, a large number of standard parts are involved, such as bolts, pins, standard die frames, etc. We can easily redefine the model and update the display results. Although there are some graphic structures that are not standardized, they need to be used frequently during design and may change their size at any time. However, this method needs to store a large number of graphic files, which greatly wastes resources.
Therefore, the mathematical model and product structure used for these product designs are fixed, the only difference is that the product structure size is different, and the difference in structure size is caused by the same number and type of known conditions. Draw the corresponding standard drawings with AutoCAD in advance. In order to overcome this shortcoming of AutoCAD itself, you can use parametric technology in the process of building the library, that is, for these stereotyped products, their serialization, generalization and standardization are relatively high.
For such products, we can replace the known conditions and the basic parameters that change with the product specifications with corresponding variables, and then according to these known conditions and basic parameters, by The corresponding application program calculates all the data required for drawing, and is automatically set on the screen by a special drawing generation software. 1 The classification of parameterized technology
The so-called parameterized drawing refers to the size of the graphic and certain design conditions (or constraints) ) Correlation, that is, the size of the figure as a function of ‘design conditions’. In order to facilitate the input of these graphics, the system has established a common library. Parametric drawing is an early CAD system relative to interactive drawing. That is, after modifying a size, the relevant size in the graphics (including other views) will be automatically updated; Second, the parameters Graphic drawing refers to that the graphics generated by the application have a parameterized function.
