AutoCAD 2006 Tutorial First Level: 2D Fundamentals
The method and number of operations that are required to accomplish the constructions are different from one system to another.3D Models In order to become effective in using a CAD system, we must learn to create geometricentities quickly and accurately. In learning to use a CAD system, lines and circles are the first two, and perhaps the most important two, geometric entities that one should master the skills of creating and modifying. Straight lines and circles are used in almost all technical designs. In examining the different types of planar geometric entities, the importance of lines and circles becomes obvious. Triangles and polygons are planar figures bounded by straight lines. Ellipses and splines can be constructed by connectingarcs with different radii. As one gains some experience in creating lines and circles,similar procedures can be applied to create other geometric entities. In this chapter, the different ways of creating lines and circles in Auto CAD 2006 are examined. Starting Up AutoCAD 2006 1 3D Models. Select the AutoCAD 2006 option on the Program menu or select the AutoCAD 2006 icon on the Desktop. Once the program is loaded into memory, the AutoCAD 2006 drawing screen will appear on the screen Note that AutoCAD automatically assigns generic name, Drawing X, as new drawings are created. In our example, AutoCAD opened the graphics window using the default system units and assigned the drawing name Drawing.The method and number of operations that are required to accomplish the constructions are different from one system to another.
