After you have created a polyline or pipe, you may decide that it is not exactly the shape you want. Or, you may want to insert another shape so that the polyline (or pipe) flows into and out of the new shape; for example, a pipe flowing in one end of a tank and out the other end.
You can split a polyline or pipe into two or more objects. The following sections show you how it's done.
Split Polyline

Figure 1 shows the selected polyline with reshape handles. In Figure
2, the arrow points to the 
splitting cursor, which turns
black when it is close to the polyline.

Figure 3 shows that the polylines still appear joined, however the reshape handles now surround only the polyline on the left. Figure 4 shows the polylines separated. You can now move the individual polylines around the picture or choose to delete one of them.
Split Pipe
|
|
Figure 1 shows the selected pipe with reshape handles. In Figure 2 the
arrow points to the 
splitting cursor, which changes to
a contrasting color when the cursor is inside the pipe.
In Figure 3, the arrow points to the split you created in the original pipe object. Note that the reshape handles now surround only the pipe on the left. Figure 4 shows the pipes separated. You can now move the individual pipes around the picture or choose to delete one of them.

NOTE: When you split a polyline or pipe, you create a new object. Therefore, if you undo a polyline or pipe split, the new object is deleted first and you must perform a second undo action to revert to the original object.
