Chapter 23 Trimming Entities
Creating a Polygon from the Intersection of
Two Polygons
On the Edit menu, click Trim, Intersection to create a new polygon from the
intersection of two polygons in your drawing. The new polygon assumes the
shape of the parts of the original polygons that overlap. The new entity has
the graphic properties of the second polygon you click on.
The original polygons are removed by this procedure. If you want to keep the
original polygons, make a copy before you begin this procedure.
To create a polygon from the intersection of two polygons
1 On the Edit menu, click Trim, Intersection, or click the Intersection
button on the All-In-One toolbar.
2 Click the first polygon.
3 Click the second polygon.
Subtracting One Polygon From Another
On the Edit menu, click Trim, Difference to create a new polygon by subtract-
ing an intersecting polygon from another. The new polygon assumes the
shape of the second polygon, with the first polygon removed. The new entity
has the graphic properties of the second polygon you click on. One applica-
tion of this command is to make a polygon with a hole in it. The first poly-
gon you click defines the shape of the hole. It must be located entirely inside
the larger polygon for the operation to result in a polygon with a hole.
The original polygons are removed by this procedure. If you want to keep the
original polygons, make a copy before you begin this procedure.
