For existing pattern fill objects, users can modify their pattern type, angle, spacing, correlation, and island detection style settings. 7.4.1 Instance 2 Modifying a fill pattern Step 1 Open a graphics file Start the AutoCAD 2002 system to open the instance file "EXAM6-1.DWG" created in chapter 6th; Step 2 Modify the fill pattern Now let's modify the angle and spacing of the fill pattern in the file. Select the icon on the Modify II toolbar and

To make the line to do n points, perhaps the novice CAD friends will immediately think of the use of a number of parallel lines in the middle school textbooks to do auxiliary line segments, in fact, do not bother, AutoCAD itself has a line to do the division points of the order "DIVIDE." First draw a segment, enter "DIVIDE" at the command line, carriage return Confirmation command, command line prompt as follows: Select the object to divide: (the mo

1, return to the desktop location, find an empty place on the desktop, click the right mouse button, in the appearance of the Decline menu, select New-text document; 2. Create a blank Notepad document on the desktop, double-click to open the Notepad document and save it as a Dfst.dll file, note the format for all files; 3, the Dfst.dll file cut, and then double-click on the CAD installation directory support document, the Dfst.dll file paste in, directly exit the window can be; 4. Aft

What if the two lines do not overlap when the two lines are cut (TRIM? The common practice is to extend two straight lines to make them intersection, and then trim the operation. If there is a large number of such non-intersecting conditions in the drawing, isn't it very troublesome to cut? AutoCAD has taken this situation into consideration for us. By modifying the system variable edgemode, we can easily trim non-Intersecting straight lines. Enter "

Recently, ArcGIS controls were used to display maps. Previously, mxd files were loaded to display maps. However, each time a map was zoomed in or dragged, the map was reloaded, if the screen or latency is serious, the real-time display of elements cannot be completed. For this reason, after I change to a file in the SHP format, the effect is significantly improved. However, the SHP file is obtained from the DWG file and n methods are introduced on the Internet. However, during actual operations,

1. the VBA script cannot be run automatically. Solution: Set the acadlspasdoc system variable to 1. Explanation: Acadlspasdoc is a system variable Type: integerLocation: RegistryInitial Value: 0Control whether to load the Acad. LSP file to each graph or only to the first graph opened in the task. 0: Load Acad. LSP to the first graph opened in the task.1. Load Acad. LSP to each open image How to Set 1? (1) Search for this value in the Registry and change the value to 1. (2)

I believe that the use of AutoCAD in the work of drawing drawings is not only in accordance with the book when the study to draw a few line segments or painting square draw circle so simple, a complex drawings often need to spend a few hours or even more than a few days of work to complete, I believe that no one is iron, There's no going to be a nap when something goes wrong. The author here on the complex drawing should pay attention to some of the p

Often contact the CAD drawing friends will find that the download to the drawings often appear after the text garbled problem, sometimes the text all show as a question mark, to our work brought a lot of trouble. How to solve such a problem? Look at this picture below, this is a line of text in AutoCAD, do not misunderstand oh, this is not Japanese, but display the wrong garbled. If you just want to know the content of a line of text, double-click

5.2.1 Example 1 draw the pressure gauge Step 1 Create a new graphics file Start the AutoCAD 2002 system and create a new graphics file for the template "ACADISO.DWT". Step 2 Draw the contour of the pressure gauge (1) First use the "Circle" command to draw a circle with a point (100,100) as the center, 50 as a radius, and then invoke the "Rectang" command to draw a rectangle between the point (85,45) and the point (115,155). The result is shown in

Next, you'll introduce a few basic, generic, change commands. For most AutoCAD commands, users can usually use two editing methods: One is to start the command, then select the object to edit, the other is to select the object first, and then edit the command at the call. In order to describe the unification, the first method is used in this chapter to modify. A command that can only use one editing method is described in the instructions for that com

Point coordinates query The ID command is used to query the coordinate values of the specified points. The call method for this command is: Toolbar: "Inquiry (query)" → Menu: "Tool (tool)" → "Inquiry (query)" → "ID point (coordinates)" Command line: ID When you use the ID command, AutoCAD gives the x, y, and z coordinate values for the specified point. Explains that the ID command can be used transparently. Distance Query function and use of 8

Today we use AutoCAD to make an exquisite three-dimensional birdcage. Here is a complete picture. Make the bottom of the Birdcage first! As pictured, draw two concentric circles, the size of the custom! Using the Cut (TR) command, cut off the second round line, as shown! Then use the stretching command (EXT), respectively, two of the circle stretching, stretching, the difference set operation, the outer circle minus the inner circle! UCS as the

In AutoCAD to draw a building plan often need to draw some objects of the floor plan, such as tables, chairs, bonsai, and so on, most objects are dedicated library can be called directly. Lotus in general building plans rarely encountered, so most of the library does not have this block, then we have to draw a hand, in fact, drawing Lotus is very simple, 5 commands can be achieved, the final effect chart is as follows: Next, let's look at how to dr

Drawing drawings in AutoCAD with similar shapes but with different sizes is a problem we often encounter, drawing in standard sizes, time-consuming and laborious. In fact, the purpose of some simple sketches is only to enable the processing workers to understand the size and shape of the parts, so in order to improve efficiency, we can use the "word substitution" method to modify the already drawn approximate graphics to quickly get the new sketch. A

First, open the AutoCAD toolbar, select UCS and view. The toolbar on the left side of the picture. Second, the use of polygon tool to draw the inner cut in the circle, the radius of 5 of the positive hexagonal Third, connect diagonally 2 points to make red auxiliary line. A circle with a radius of 2 on the midpoint of the Red guide line Using Drawing > Surface field to convert hexagonal and circle to face Use drawing > Entity > Stretch to stretch

option Options Role Add (added) Add the fitting point in the spline curve. AutoCAD will then fit the spline curve with the newly set point. Close (closed) Closes the open spline curve and causes its tangent to be contiguous at the endpoint, and for closed spline curves, the item is replaced by Open. Delete (delete) Deletes the specified fitting point from the spline curve and then uses t

invoked, the system first displays the current setting of the "extend" command and prompts the user to select an extension boundary: Current Settings:projection=ucs, Edge=none Select Boundary edges ... Select objects: After the user determines the extension boundary, the system further prompts as follows: Select object to extend or shift-select to trim or [Project/edge/undo]: At this point, the user can choose the following actions: (1) Directly select the object to be extended with the
