autocad measurement

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

8.7.1 functions and usage of graph statistics You can use the "status" command in AutoCAD to query the basic information of the current graph, such as the current graph range and various graph modes. The command is called as follows: Menu: Tools → inquiry → status )] Command Prompt line: Status In addition, you can use status in the prompt dim to display the values and descriptions of all system variables. For details about the dim prompt, see Chapter

First, enter the coordinate value in Excel. We put the X coordinate values into column A, y coordinate to column B, and then merge columns A and b into column C. Since the two-dimensional coordinates in AutoCAD are separated by commas, we enter =a2 in the C2 cell, and a pair of coordinate values appear in B2 and C2. We use the mouse to drag the C2 formula to copy, you can get a set of coordinate values. Then, select the coordinates of the points tha

Example 1 Basic examples 1 , new Project Start Visual Studio 2005, create a new project named CAD development, as shown in the following illustration: 2 , adding references Add AutoCAD references AutoCAD 2007 type library and autocad/objectdbx Common 17.0 type library, as shown in the following illustration: 3 , global variable definition Defined in the

What methods and techniques should we use if we want to trim an object outside a range of AutoCAD drawings? As shown, to the right figure part of the circle outside the line to cut, the general method is to select the cutting edge, and then select the segment to be trimmed can, in fact, AutoCAD also has a relatively simple way. Click to enlarge 1. According to the general execution of the crop command,

3.3.4 Instance 4 uses views and viewport (Viewport) to view graphics Step 1 Open the graphics file "city base MAP.DWG" (1) This example uses the sample file "city base map.dwg" provided by AutoCAD 2002, which is also stored in the "sample" subfolder of the AutoCAD home folder. Run the AutoCAD 2002 system and open the file as shown in Figure 3-31. Step 2 Use th

2.7.1 using object capture Object capture is one of the most important tools in AutoCAD, the use of object capture can be precisely positioned, so that users can directly use the cursor in the drawing process to accurately determine the target point, such as center, endpoint, pedal and so on. In AutoCAD, the user can do the object capture mode at any time through the following ways: (1) Use the object sn

4.5.1-point drawing and setting 1. Drawing of points The AutoCAD Midpoint object (point) is probably the simplest graphic object, and the user only needs to specify its coordinates. Although drawing is simple, AutoCAD still provides a variety of ways to draw: Single Point method: Call once command to draw only one point (1) Multi-point method (multiple points): Invoke a command once to draw multiple poi

In addition to typing commands at the command line, users can invoke commands through menus and toolbars. 2.2.1 Use menu 1. Drop down menu The menu bar in AutoCAD is a drop-down menu, a cascading hierarchy. The main menu, displayed in the menu bar of the AutoCAD window, allows the user to click the left mouse button to eject the corresponding menu item on the main course item. For example, click the Tool

For example, the database administrator needs to enable the Oracle database system to perform self-monitoring. When the server's CPU usage reaches, the system automatically sends an alarm to the database administrator. When the tablespace usage reaches 90% of the total capacity, the system automatically notifies the database administrator. These functions are very useful for database administrators. The Enterprise Manager of the Oracle database system provides multiple ways for administrators to
