AutoCAD 2006 and higher versions

Sometimes, you would like to combine lines or arcs. Or, we notice that the lines that have been drawn in a drawing are made up of pieces. The reason of this is that the draftsman has not made the proper editing over the project . Here is the solution for all these problems, JOIN command. It has a very simple way of working. You select an entity first and then the other entities that will be joined to the first one that you have selected, and that’s it the operation is completed. The one rule is that the selected entities are not identical and they are on the same path.

Fig.1

Command: JOIN
Select source object:
Select arcs to join to source or [cLose]:
Select arcs to join to source: 1 found

In Fig.1, you can see how the JOIN command works for two different arcs that has the same center and radius and have space in between them. After selecting the first arc, the ‘cLose’ option appears. If we select this option, then our arc will be closed to form a circle. Instead, if we select the second and the third lines than all of them will be combined. What we should pay attention to is to make our selection in counter clock wise direction. In the example, the arc that is on the right side is selected first.

Fig.2

Command: JOIN
Select source object:
Select lines to join to source: 1 found
Select lines to join to source: ENTER
1 line joined to source

In fig. 2, we are joining two lines that are on the same line. Even though the execution of the command is same the messages and options that appear are quite different. JOIN command is as simple as this. Before I finish, let me list the type of entities that can be used with the command: LINE, POLYLINE, ARC, ELLIPTICAL ARC, SPLINE, HELIX.
