Converting Lines to Polyline

Joining multiple lines to create a polyline can be tedious and time-consuming if it is done manually. Using the Convert Lines to Polyline button on the CAD Toolbar, (Classic view) or Convert Lines to Polyline, in the Drawing Tools list, in the Picture list, in the Picture group, on the Format tab (Ribbon view), you can easily draw the individual lines required and convert them to a polyline. You can create single or multiple polylines.

Converting lines to a single polyline

The following diagrams show an example of creating a single polyline from individual lines.

The lines are drawn, as in Figure 1, and then all are selected. When you click the Convert Lines to Polyline button, it extends the lines (as shown in Figure 2), and then it trims the lines (as shown in Figure 3). For more information, refer to Extending Lines to Intersect and Trimming Lines at the Intersection.

Figure 4 shows the points of the polyline. The points of a polyline are determined when two lines are connected and have the same intersection point at the start or end point.

Converting lines to multiple polylines

The following diagrams show an example of creating multiple polylines from individual lines.

As with converting lines to a single polyline, the selected lines are first extended to the intersection points and then trimmed. In this example, two polylines have been created.

Figure 4 shows the points of each polyline; that is, points 1-1 through 1-6 are the points of Polyline 1 and points 2-1 through 2-3 are the points of Polyline 2. The points of a polyline are determined when two lines are connected and have the same intersection point at the start or end point.
