Concatenate Lines
Concatenate a line chain as a single line. You can also concatenate lines with no common end points. The program will connect the lines by adding a line between them.
You can select polylines and arcs as lines to be concatenated. You can use snap functions when pointing the line chain.
- Select Drawing | Line Tools | 
 Stretch > 
 Concatenate Lines. - Select the search function of a line chain.
 - Select the lines to be concatenated.
 - Select Confirm.
 
 When pointing the lines one by one, click them in the order in which you wish them to be concatenated.

Note: 
  - Modify the concatenated line using its grip points.
 - Coincident constraints will not be created for the points of the concatenated line (2D Constraint Manager).
