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 "
During secondary development based on AutoCAD, common tutorials are about defining some custom commands in the DLL, and then loading the DLL using the netload command, execute custom commands to execute custom functions. This method is very simple in learning, but it is too amateur to use it in formal products without professionalism. Of course, more professional is of course the same as AutoCAD, providing
1... Net-based development(1). Net API IntroductionIn AutoCAD 2006 and later versions, Autodesk added. Net API for its development .. . 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
I found that as the last speaker will have some advantages, because we can use more time to give you the most important Autodesk products, namely AutoCAD. It is not too much to say that AutoCAD is the most important product of Autodesk, because its history is as long as that of Autodesk company, since the first version has been developed for 25 years, in other words, there have been 1/4 of centuries of time
Using C # For secondary development of AutoCAD (1) As we all know, the main tools used for secondary development of AutoCAD are ObjectARX, VBA, and vlisp. But their advantages and disadvantages are obvious: ObjectARX has powerful functions and high programming efficiency, but its disadvantage is that programmers must master VC ++, which is very difficult to learn; although VBA and vlisp are simple and eas

as we all know, the main tools used to develop AutoCAD for two times are: Objectarx,vba,vlisp. But their advantages and disadvantages are obvious: Objectarx powerful, high programming efficiency, but its disadvantage is that programmers must master VC + +, and the language is very difficult to learn; VBA and Vlisp are easy to get started with, but they seem powerless to develop large programs. Is there a language that can combine their merits and try
Hello everyone, today I continue to introduce you to use C # for AutoCAD two development. In this lecture, we mainly introduce the problems in the previous example. In the last example, I used the AutoCAD-Type library to communicate between C # and AutoCAD, but this approach has two fatal drawbacks. The first drawback is that every time you debug the program, C
All versions of AutoCAD for Windows support the setting for default save as format, which is the format for modifying the defaults saved file in the OP settings for file interaction between different working environments. But AutoCAD2013 for Mac does not have this setting option, so that for a long time, every time to give someone to send a diagram, you need to use "Save as", and then choose the low version format, and then save, very inconvenient. So
1, CAD object: A CAD file (DWG file) that corresponds to a database, all components of the database, see (including points, polylines, text, circles, etc.) and invisible (layer, line, color, etc.) are objects, the database itself is an object. Graphic objects such as lines, arcs, text, and callouts are objects. Style settings, such as Linetype and dimension styles, are objects. Organizational structures such as layers, groups, and blocks are objects. Graphical displays, such

In a technical forum to see a friend mentioned such a question: how quickly in AutoCAD to draw multiple concentric circles? To this question Netizen's answer is various, has the reply to say with the deviation command, has the answer with the array ... Of course, there are friends. Presents a more practical VBA solution and AutoLisp solution. I think that the use of VBA or AutoLisp as a solution is of course a very good way, but since the landlord ra
Hello everyone, today I will continue to introduce you to the secondary development of AutoCAD using C. This section describes the problems in the previous example. In the previous example, I used to reference the AutoCAD 2004 Type Library for communication between C # and AutoCAD, but this method has two fatal disadvantages. The first drawback is that each d
In mechanical engineering drawing, the Central line is the most common kind of graph line, the application scope is very wide, the use is very frequency tight. Although AutoCAD provides the command to draw straight lines, but does not directly provide the command to draw the standard centerline, if the user wants to draw the standard centerline, it is necessary to set the line style and proportion of the standard centerline according to the national d

The current popular development of AutoCAD tools, one is Objectarx, and the other is AutoCAD with VBA (AutoCAD built-in Visual Lisp was also counted as a, but it can only develop a few small programs, so it can not be compared with the previous two tools). But both have obvious deficiencies, to VC + + based on the development of the function of Objectarx is very
