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.

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

Arrays are a form of AutoCAD replication, and arrays tend to have an advantage over simple replication in the case of regular multiple replications. In AutoCAD, the array is divided into two basic types: rectangular array and annular array. Rectangular array-Multiple-row and multiple-column replication, and the ability to control the number of rows and columns and the spacing of rows/columns. Annular arra

3.4.1 Mvsetup Command This command is used to set the graphic specification, which is invoked as follows: Command line: Mvsetup When this command is invoked, AutoCAD prompts the user whether to enable drawing space: Enable paper space? [No/yes] The use of this command in the drawing space is detailed in chapter 17th. Select the "No" option in this section to further prompt the user to specify the unit type, scale factor, drawing width, and heigh

Introduction to 8.9.1 Object features In AutoCAD, object characteristics (properties) is a broad concept, including color, layer, line style and other general features, but also includes a variety of geometric information, but also related to specific objects of additional information, such as the content of text, style and so on. In the previous chapters we have learned to use various editing, modification, and query commands to access the attribut

This feature option is currently available in autocad2010 and needs to be checked at the time of installation. -------------------------------------------------------------- If it is not installed, you can reinstall the Toolkit from the Control Panel-Add and Remove Programs, and some commands will be useful. Starting with AutoCADR14 Autodesk has added a program based on AutoCAD, the extension tool. AUTOCADR14 is called the "bonus program", the Engli

In the previous article, junqilian used Amazon Simple Queues Service (SQS) to achieve remote interaction with AutoCAD. This article describes how to use Amazon Simple Queue Service (SQS ), here we will introduce how to use Microsoft's Windows Azure Queue Storage to implement similar functions. This is also an improvement. Generally, the most intuitive message passing is a string, but other types such as common objects can also be passed through the qu
