Working with regions

A region is a different kind of 2D object on which you can perform Boolean operations, such as Union, Subtract, and Intersect. You can convert closed 2D objects into a region using the REGION command or using the Region tool from the expanded Draw panel:

Let’s make two simple regions and then we will perform Boolean operations on them.

We will learn how to make regions using two closed geometries, that is, a circle and a triangle, as shown:

Figure 3.35: 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:

1. 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 the Polyline tool.
2. Now, select the region tool from the expanded Draw panel or use its command...
