LEARNING OBJECTIVES

After completing this lesson, you will be able to:

1. Edit the width of a Polyline.

2. Join Polylines.

3. Convert a Polyline to a spline.

4. Convert a basic Line into a Polyline.

5. Join Lines, Arcs and Splines.

EDITING POLYLINES

The POLYEDIT command allows you to make changes to a polyline s option, such as the width. You can also change a regular line into a polyline and JOIN the segments.

1. Select the POLYEDIT command using one of the following:

   • TYPE = PE

   • PULLDOWN = MODIFY / OBJECT/ POLYLINE

   • TOOLBAR =MODIFY II

Note: You may modify Multiple polylines simultaneously.

1. PEDIT Select polyline or [Multiple]: select the polyline to be edited or M

2. Enter an option [Close/Join/Width/Edit vertex/Fit/Spline/Decurve/Ltypegen/Undo]:
   select an Option (descriptions of each are listed below. )

Note: If you select a line that is NOT a POLYLINE , the prompt will ask if you would like to turn it into a POLYLINE.

OPTIONS: (Step by step instructions in the following exercises)

CLOSE (Refer to Exercise 24A)

CLOSE connects the last segment with the first segment of an Open polyline. AutoCAD considers a polyline open unless you use the Close option to connect the segments originally.

OPEN (Refer to Exercise 24A)

OPEN removes the closing segment, but only if the CLOSE option was used to close the polyline originally.

JOIN (Refer to Exercise 24D)

The JOIN option allows you to join individual polyline segments into one polyline. The segments must have matching endpoints.
