Most of the time we draw using precise measurements of lengths and angles and radii. But when modifying and updating drawings we may simply draw freehand. We show you the drawing basics and much more in our Autocad 2d courses.
When drawing in Autocad there are three methods of choosing drawing tools. You can click on a  tool icon from the top Ribbon, or go to the Draw drop-down menu, or type in the keyboard shortcut for the tool. For example, to draw a line in Model space, choose the line tool, or type L, Enter into the bottom Command line, or at the cursor if Dynamic Input in active.
You will then be asked a series of questions relating to the position of the endpoints of the line – these appear at both the Command Line and the cursor. Simply follow the prompts and hit Enter to apply. Similarly with the Circle tool: select one of the circle options – note that there are many options in the drop-down menu, depending on the information you have regarding radius or diameter, centre point position, etc. If you now double-click on the circle drawn the Properties panel will appear, allowing you to change the radius or the object’s layer, line weight, etc.
If you turn on Ortho on the bottom Status bar, or hit F8 on your keyboard (Mac: Command + L), you will draw the lines orthogonally, that is horizontally and vertically. This is good for drawing up floor plans and elevations.
Other tools ask you to enter other pieces of information, for example, the Rectangle tool (type REC into the Command line) will ask for two adjacent corner points, or the width and height of the shape. It’s always a good idea to look at what the Command line is asking, and follow the prompts exactly.
