The coordinate system of AutoCAD is divided into world coordinate system and user coordinate system.

The world coordinate system is the default coordinate
The following will enter the graphics space provided by AutoCAD for the user. The main purpose is to use AutoCAD to draw graphics, so first of all to understand the Graphics object in the environment. As we have seen in real life, AutoCAD provides a three-dimensional space, and usually our modeling work is done in such a space.
System variables and environment variables in AutoCAD (from the official Help file) AboutSystem andEnvironment Variables(AutoLISP)(1)System VariablesAutoLISP applications can inspect and ChangeThe value of the AutoCAD system variables with theGetVar andSetvarfunctions.;;
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 t
AutoCAD Object, but it does not exist in C #. I almost gave msdn to this function, then I went to various C # forums and asked you experts. The results were not solved. Haha, there may be fewer people using C # in China. I still saw an article on a foreign Forum about this problem to solve this problem. Use the following statement to obtain the active AutoCAD Object:
(Acadapplication) Marshal. getactiveo
an article is to talk about this issue to solve the problem. Use the following statement to get the currently active AutoCAD object:(acadapplication) marshal.getactiveobject ("autocad.application.16")(for CAD2000 and CAD2002, change 16)of course, the above statement must be opened in the case of AutoCAD to use, or there will be an error, for AutoCAD is not open,

1.4.1 Start AutoCAD
First, we introduce how to enter the graphical interface of AutoCAD. Select the "AutoCAD 2000" package in the operating system "start" menu (WINDOWS95/98 or WindowsNT4.0) and select "AutoCAD 2000", and AutoCAD

Of course, the preceding statements can be used only when AutoCAD is opened. Otherwise, an error may occur. If AutoCAD is not opened, you can use the method of the previous ar

Q: How do I use the callout style of the current graphic in other files?
There is an import and export feature of annotation styles in A:cad, and you can use the annotation style import and export function to refer to the callout style in the current graphic in a new shape. Here we take AutoCAD R14 as an example to describe the specific operation process.
AutoCAD R14 has an "

Net API provides a series of managed outsourcing classes (managed Wrapper class), allowing developers.. NET Framework.. NET language, such as VB.. net, C #, and managed C ++. Its advantage is completely object-oriented.(2) Main differences between. Net APIs and traditional ObjectARX APIsFirst, in the VC environment,Pr
Two development of AutoCAD can be used: Objectarx,vba,vlisp. But instead of borrowing them here, you use C # development directly.
There are two ways to class libraries and applications:
Method 1:vs2010 Develop AutoCAD 2008 class Library
Create a dynamic library, use netload from the AutoCAD command line, and then execute its method

on this issue is to solve the problem. You can get the currently active AutoCAD object by using the following statement:
(acadapplication) Marshal.getactiveobject ("autocad.application.16")
(For CAD2000 and CAD2002, the 16 is changed to 15)
Of course, the above statement must be in AutoCAD open the case can be used, or there will be errors, for AutoCAD did no

When users work in AutoCAD system, the main input device is keyboard and mouse, the following describes how to use the keyboard and mouse in AutoCAD.

AutoCAD, like previous versions, provides both a graphics window and a text window. You typically display some of its text windows and command
keywords for object entities, and records are added to those containers (records are objects) and records are modified.3, the symbol table and the dictionary is different: the symbol table is as follows 9, each symbol table can only store certain types of objects (such as the block table can only store block table records, the layer table can only store layer table records), and the dictionary is a common container, can store any type of object. (Typically, most of the objects are manipulated b
As the Windows 7 and Windows 8 systems gradually mature, more and more users (especially my girlfriend's hour, often used, in order to help her work ), windows 7 and Windows 8 systems are divided into 32-bit and 64-bit systems. Therefore, when you choose to install the CAD version, you must first determine whether your system is 32-bit or 64-bit!Some friends may ask, How do I know whether my system is 32-bi
