Chapter 4 : Familiarity with drawing units
Lesson 1 : definition style of a measuring unit
Lesson 2 : Geometric drafting by using architectural measures
Lesson 3 : Method by metric system
Autocad is a professional but user friendly program with a broad scope of information. This collection teaches step by step drawing geometric shapes and their measures very clearly. At first, this program focuses on simulation and modeling and you will see various methods and tools to work with. Ribbon is one of the most important icon which acts as a big box full of icons in its shelves. In addition to Ribbon, Palette is another brilliant part in interface. Palettes provide quick access to designing items, properties and commands. The lowest part in interface is called status bar which gives and displays information about the settings. By putting mouse indicator on each item, we can see their status from guide frame. To start a new program in Autocad , it is better to know how we can open a file. DWG suffix which is a short form of drawing. This drawing is used for introducing the file and saved sample.
There are different commands such as panning, zooming and regen which are used a lot in precise mathematical calculation. Saving the documents can be done easily with the help of instructions in Autocad. Drawing shapes and lines are necessary and full application in autocad as well as using ortho and polar. They are used for determining angles like the angle 90 degrees . For drawing circles, you can activate grids and then by drawing the radius , in drawing these shapes , dimensions are very important. Units play some roles in measuring the architectural plans which are mostly inch and foot. Metric system can help for measuring units in autocad as well.
You also see some features such as snap object to draw shapes. Before beginning, you ought to activate grid and dynamic input from status bar. There are automatic parts in object snap too. To draw a quadrangle, ellipse and polygon is another feature of autocad , like other shapes, you can use commands. Line command is really central in all drawings. Copy and move are other commands which are used in drawing geometric shapes. Omission and addition are the other methods in drawing geometric shapes, then offset can be really vital. Actually offset command is used for copying. The other commands are undo and redo which are used for returning the shapes in their first mode.
Hatching is one feature which has been left from the age of pencil and paper. Adding hatch effects increase the attraction of image. Another feature is fillet feature , by using them , we can form the points and corners as curve. Layers can also be an important concept which are used in organizing drawings. Layer properties manager is the main icon for being activated and inactivated in creating and adjusting shapes and drawing. After creating shapes and drawing the page of autocad most of the times we need to add a text, this is done by guide text , text arrangement and text mode command , then the next stage is editing them. All the calculations which have been done and formed on the shape. To adjust the dimensions are also key instruction in autocad. Whenever we are going to copy a shape, converting it to a block is a good idea. Block means a collection of geometric shapes whose name is determined in the image. At the end, the feature of printing is also possible, by choosing favorite printer and giving commands to the program.
