CHAPTER 1

INTRODUCING AUTOCAD 2020

AIMS OF THIS CHAPTER

The contents of this chapter are designed to introduce features of the AutoCAD 2020 window and methods of operating AutoCAD 2020.

OPENING AUTOCAD 2020

AutoCAD 2020 is designed to work in a Windows operating system. In general, to open AutoCAD 2020 double-click on the AutoCAD shortcut in the Windows desktop (Fig. 1.1).

When working in education or in industry, computers may be configured to allow other methods of opening AutoCAD, such as a list appearing on the computer in use when the computer is switched on, from which the operator can select the program he/she wishes to use.

When AutoCAD 2020 is opened, the Start page appears, giving access to recent drawings, system information and the Start Drawing button (Fig. 1.2). After starting a new drawing a new window is shown, depending upon whether a 3D Basics, a 3D Modeling, or a Drafting & Annotation workspace has been set as QNEW (in the Options dialog). In this example, the Drafting & Annotation workspace is shown and includes the Ribbon with Tool panels (Fig. 1.3). The Drafting & Annotation workspace shows the following details:

Ribbon: which includes tabs, each of which when clicked will include a set of panels containing tool icons. Other tool panels can be seen by clicking an appropriate tab.

Fig. 1.4 The Menu Browser

Menu Browser icon: A left-click on the arrow to the right of the A symbol at the top left-hand corner of the AutoCAD 2020 window causes the Menu Browser menu to appear (Fig. 1.4). Workspaces Switching menu: appears with a click in the lower right corner. Workshop Switching button in the status bar (Fig. 1.5).

Command line: can be changed as shown in Fig 1.6.

Tool panels: each includes tool icons appropriate to the panel. Taking the Home/Draw panel as an example, Fig. 1.7 shows that placing the mouse cursor on one of the tool icons in a panel brings a tooltip on screen showing details of how the tool can be used. Two types of tooltip can be used in AutoCAD 2020. In the majority of future illustrations of tooltips, the smaller version will be shown. Other tool icons have popup menus appearing with a click. In the example given in Fig. 1.8, place the cursor over the Circle tool icon and a tooltip appears. A click on the arrow to the right of the tool icon brings down a popup menu showing the construction method options available for the tool. Quick Access toolbar: The toolbar at the top left of the AutoC...
