AUTOCAD believes that people engaged in computer-aided design is more common, he is a graphic aided design software, with powerful graphic design auxiliary functions, let us give you a brief understanding of AUTOCAD (hereinafter we refer to CAD);
A computer (can support graphics acceleration)
Download a temporary learning CAD software
Open the computer, and then install the CAD software in the computer, after the installation, you can see the CAD icon on the desktop, double-click the icon to open the CAD, you can see the open interface of CAD (design interface);
Click Open, enter the design interface of a single file, here I will briefly introduce you to the use of some common elements, circle, rectangle, polygon, straight line drawing;
To draw a circle, first click the icon of the circle on the left toolbar, as shown in the figure, then click in the working area of the graph, and then pull away from the periphery, you can see that the point just clicked the mouse, is the center of the circle, the distance pulled out, is the radius of the circle, click the mouse again at this time, indicating that this position is determined as the radius size;
Polygon drawing method, first click the icon of the polygon on the left toolbar, as shown in the figure, then click in the working area of the graph, and then open to the periphery, you can see that the point just clicked the mouse, is the polygon, the distance pulled out, is to increase the distance of the polygon, click the mouse again at this time, indicating that this position is determined as the distance of the polygon. That's determining the size of the polygon;
To draw a rectangle, first click the icon of the rectangle on the left toolbar, as shown in the figure, then click in the working area of the graph, and then pull it to the right. You can see that the point just clicked by the mouse is the upper left corner of the rectangle, and continue to pull diagonally to the lower right side, at this time the size of the four sides of the rectangle continues to increase, at this time click the mouse again. Indicates that the length and width of the rectangle are determined;
The graphics card of the computer must be able to support the graphics acceleration function, especially when the graphics are complex, the graphics card is insufficient, and the line will be stuck and the graphics distortion;
It is best to buy a CAD study book and preview it first.
