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

Designers in the drawing of some simple three-dimensional graphics, usually need to mark the processing size, such as furniture, shelves and other simple three-dimensional graphics. See a lot of friends are not in the CAD to mark the size, but in the CAD to draw the figure after the print out, with a pen and then mark the size. Today we are in the CAD for a simple shelf three-dimensional graphics dimensioning, for friends as a reference. There is no three-dimensional annotation function in

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

1, we in the computer empty folding place then right click "Blank Place" then in the menu then click "New-Text document" as shown in the following image; 2, then you can create a blank Notepad document, double-click Open the Notepad document, and then save it as a Dfst.dll file, note that the format for all files; 3, the Dfst.dll file cut, and then we enter the AOTOCAD 2007 installation directory support document, the Dfst.dll file paste in, if there is to replace us click to con

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

A little summary of recent projects related to CAD data1. About listIt can save a number of different elements, but how do you determine what kind of element it is when you take an element? When you take an element, you can determine what type of element is in the list by calling the GetClass method and comparing it to the class. The element is then coerced into a type cast.2. Reference block coordinates for data in AutoCAD.A block reference in a DXF file has a definition of coordinates that can
