In AutoCAD cartography sometimes we need to do some text annotation, in the industrial drawings often encounter some cubic meters, square meters, etc. with superscript unit symbol, then how to enter in AutoCAD with superscript symbol? Using multiline Text command Mtext, enter "m3^" in the text box: Using the mouse to select the 3 and "^" symbol that we need to make superscript, click the Stack button on

If we need to replace a lot of text with the same text in one file, we usually think of a substitution command. In previous versions of AutoCAD, you had to load the CHT feature and use the CHT related commands to complete the replacement work. But in the AutoCAD R14 can complete the replacement work directly without reloading the CHT. The method in R14 is to click the "Properties" button in the status bar,

The concept and function of 6.3.1 pattern filling This is often the case when drawing graphics, such as drawing a section or section of an object, using a pattern to fill a specified area, a process called a pattern fill (Hatch). Pattern fills are often used to express the material type of an object in a cross-sectional view, which increases the readability of the graphic. In AutoCAD, no matter how complex a pattern fill is, the system considers it

When a user constructs a selection set in AutoCAD, the select set can be filtered using either the Quick Select (Quick Select) or the Objects Selection Filters (Object Selection Filter) dialog box to filter the selection based on object attributes or object types. That is, the user can select only objects that meet the specified criteria, and other objects will be excluded from the selection set. With a quick selection, you can quickly define a selec

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". Step 2 Graphic Drawing (1) Draw two lines (line), the endpoint coordinates are ( -12.5,0), (12.5,0) and dots (0,-12.5), (0,12.5). (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 (

This is an AutoCAD model to do badminton tutorial, modeling is not difficult. The main application to the CAD commands are as follows: L line, Region surface field, Rectang rectangle, C circle, spline spline line, revolve rotation, M Mobile, rotate3d three-dimensional rotation, 3DARRAY three-dimensional array, torus ring. Final Effect Chart The production process is as follows. In CAD, press the picture to draw a rotating surface. Region crea

Example 4 Drawing House floor plan Step 1 Create a new graphics file Starting the AutoCAD 2002 system and creating a new graphic file with "ACADISO.DWT" as the template; Step 2 Draw Guides (1) First use the "xline" command to draw the horizontal reference line. Select the icon on the Draw toolbar and, as prompted, enter the command line: Command: _xline Specify a point or [Hor/ver/ang/bisect/offset]: H Enter NBSP;

5.3.1 Instance 2 draw a telephone Step 1 Create a new graphics file (1) to start the AutoCAD 2002 system, "ACADISO.DWT" for the template to create new graphics files. Step 2 draw the basic outline (1) using the "Rectangle" command, draw 4 rectangles between the point (10,10) ~ (70,90), (17,20) ~ (32,80), (36,63) ~ (66,83) and (38,24) (43,27) respectively as the basic contour, as shown in Figure 5-24. Step 3 Modify Contour Line (1) • Now use the

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
