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

How to save a high version of AutoCAD files to a low version format in your computer Method One: 1, open the file and click on the upper left corner of the "file"-"Save as"; 2, in the pop-up "graphics Save as" dialog box, set the filename, and then click the "File Type" Drop-down box, from which to select a lower version of the CAD file save format, click Save. Method Two: 1, open the CAD, click on the menu bar "Tools"-"op

2.6.1 Create a new graphic After the AutoCAD system is started, the user can invoke the "new" command to create a new graphic, which is called by: Toolbar: "Standard (Standard)" Menu: "File" → "New ... (new) " Command line: New When this command is invoked, the system displays the Today window, where users create new graphics using templates, wizards, and more, as described in 3.1. 2.6.2 Open an existing graphic Users can use the "open" command

/undo]: The specific roles are as follows: (1) "Close": a closed, open, multiple-segment line. Note that even if the start and end points of a multi-line line are at the same point, AutoCAD still considers it open and must use this option to close it. For closed multi-line lines, the entry is replaced by Open, which works the opposite way. (2) Join (merge): Merges a line, arc, or multi-segment line object with other segments of the line that coinci

Features and use of 8.5.1 list display The list in AutoCAD displays commands for displaying database information about objects, such as layers (Layer), handles (Handle), and so on. In addition, depending on the selected object, the command also gives the additional information associated with it. The call method for the list command is: Toolbar: "Inquiry (query)" → Menu: "Tool (tool)" → "Inquiry (query)" → "list (listing display)" Command line: L

By default, objects are plotted in the order in which they were created. In some special cases, such as two or more objects covering each other, it is often necessary to modify the drawing and printing order of the objects to ensure proper display and printout. AutoCAD provides a "draworder" command to modify the order of objects. 7.3.1 Instance 1 changing the Order of graphics Step 1 Open a graphics file Start the
