Example 1 draw hex nut part diagram Step 1 Create a new graphics file Start the AutoCAD 2002 system and create a new graphics file for the template "ACAD.DWT".

(2) Draw two circles (Circle), all with point (0,0) as the center, the radius is 4, 10 respectively. (3) Now to draw a positive hexagonal. Select the icon on t

We know that drawing graphics in AutoCAD is proportional, but when dimensioning, there are two dimensions associated with callouts in the property manager: Callout linear proportions and callout global proportions. As pictured. If we select the "Callout-style" menu and open the callout style manager, you can see the option to adjust the callout's linear ratio under the main Units tab. Under the Adjustments tab, you can see the option to adjust the gl

When drawing on drawings, you should determine the proportions before starting. This scale is the ratio of the size of the drawing object to the actual size of the object represented by the graphic. For example, every one-fourth inches in a building graphic might represent a foot of a room floor plan. 　　The selected proportions must make the object's graphics full of drawings. In AutoCAD, this process is reversed. You can use the specified unit type (

Nodes are the key points in AutoCAD, which are often used to make positioning, tagging, moving, copying and other complex operations. In the practical application we will find that sometimes we choose a slightly more complex graphics does not appear node, to our graphics operation brought a little trouble. There is a trick to solve this problem: When the selected graphics do not appear node, use the copied shortcut key Ctrl + C, the node will be dis
