The segment is highlighted. 3 Check the Hide check box on the edit bar. To make a hidden polyline segment visible 1 Enter vertex editing mode. 2 Position the pointer on the polyline segment you want to make visible, then click.

Deleting a Vertex or Segment As a part of vertex editing, you can delete a vertex or segment and change the actual shape of the poly entity. Deleting a segment or a vertex at the startpoint or endpoint of a multi-segmented polyline removes the segment between that vertex and the next one. Deleting any other vertex creates a single segment between the vertices on either side. After you use vertex editing, you may find that the resulting entity contains extra vertices. If you delete a vertex that is colinear with the startpoint and the endpoint of an adjacent segment, or one that is located on top of another vertex, the shape of the entity does not change. The Clean command deletes all the extra vertices in the current selection set. This speeds up the redraw or print process, plus it affects the results of some trim operations. To delete a vertex and change the shape of the selected entity 1 Enter vertex editing mode. 2 Select the vertex you want to delete. If selected, the vertex box is solid. 3 Click the Delete Vertex button on the edit bar. To delete a segment of a poly entity 1 Enter vertex editing mode. 2 Select the segment you want to delete. 3 Click the Delete Segment button on the edit bar. 306 | Chapter 24 Reshaping Entities
