We will learn how to make regions using two closed geometries, that is, a circle and a triangle, as shown:
Figure 3.41: A circle and a triangle
In the following example, we will first make these closed drawings and then we will learn how to convert them into regions:
- Make the circle using the circle tool from the Draw panel and use any radius value. Also, make the triangle with any dimensions using the line of polyline tool.
- Now, select the region tool from expanded Draw panel or use its command, REGION.
- The command line will now prompt you to select the objects. Select the circle and triangle and press Enter.
- Visibly, the drawings will still look the same but they are now converted into regions and a message confirming this will show up above the command line, as shown:
Figure 3.42: The Command Prompt when objects are converted to regions
So, now the circle and triangle are converted into two separate regions, which are basically rigid 2D shapes. So, after the region tool, let's learn about the point tool, which is also called nodes, in AutoCAD.
