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.

Exercise 6.1


Continuing the mechanical project from Chapter 4, Structuring Projects and Following Standards, we are going to measure the volume by applying text and creating a table. DraftSight, as other DWG softwares, is dimensionless, we assume the length unit is millimeters (mm)

  1. Open the drawing PROJECT1-CH4.DWG.

  2. To calculate the volume of both parts, the best way is to use a new layer to create a contour. Create a layer called AUXILIARY, with a different color and activate it.

  3. With the POLYLINE command, create a closed polyline contouring the left view by applying the Arc option on the top fillets. The GETPROPERTIES command applied to this polyline indicates an area of 7653.429 mm2.

  4. Apply the EDITPOLYLINE command to create a polyline from the two arcs and lines of the top hole. The GETPROPERTIES command of this polyline indicates an area of 278.54 mm2.

  5. The circular hole area is 176.715. So the total area is 7653.429-278.54-176.715, that is, 7198.17mm2. The width of each part is 20mm, meaning...
