Getting Started with DraftSight

By: JOAO ANTONIO C DOS SANTOS

Overview of this book

Computer-aided design (CAD) uses computer systems to assist in the creation, modification, and analysis of a design. DraftSight is a 2D computer-aided design (CAD) software application. DraftSight includes all the main tools to draft with precision, and it works with DWG files, the most popular CAD file type. It runs on a wide variety of operating systems, including Windows, Mac, and Linux. Getting Started with DraftSight addresses all the main phases for executing and printing a mechanical project. These concepts and commands can easily be applied to other areas. Beginning with the very basic concepts, and going through all the necessary drawing steps, you will finish by printing a full scale mechanical drawing. The illustrative examples will help you understand the design process and teach you how to utilize DraftSight features in your mechanical design projects. You will start with an overview of the mechanical design process, which will help you understand the different commands, tools, and tasks involved in DraftSight projects. You will then proceed to executing all the phases of the design process. This includes setting up a drawing, drawing and editing with precision, organizing with layers, and finally obtaining valid information from the drawing. Furthermore, you will also learn to apply fills, patterns, and dimensions, and the process of defining and printing sheets. With "GettingStarted with DraftSight" you will learn how to specify and document parts and print drawings with the help of DraftSight. Towards the end of this book you will be introduced to some advanced concepts like additional layer commands, and methods to reference other drawings or images, which can be very useful when dealing with complex projects.

Drawing rectangles and polygons


The RECTANGLE command (alias REC, on the Draw toolbar, or Draw main menu) creates polylines with a rectangle shape. A polyline, as it will be detailed later, is a single entity composed by a continuous sequence of segments and/or arcs. By default, it prompts for two opposite corners:

: RECTANGLE
Options: Chamfer, Elevation, Fillet, Thickness, line Width or
Specify start corner» P1
Options: Area, Dimensions, Rotation or
Specify opposite corner» P2

The Chamfer option allows the user to apply a diagonal cut in all four corners. The Fillet option allows the user to round all corners. Elevation and Thickness are only for 3D, thus are not useful. line Width allows defining a width for the rectangle. After defining the first corner, additional options are available: Area allows the user to define a rectangle by one of the sides and area. Dimensions defines the rectangle by horizontal and vertical dimensions. Rotation defines a rotated rectangle.

The POLYGON command...
