The Join tool allows you to attach a number of objects together into a single object. The Join tool is almost exactly like PowerCADD's Attach command, with a few important exceptions.
Paths are important for several reasons.
Second, when paths are printed or plotted, they are actually treated as a single object. This means that a single line dash pattern is used for the entire object, thus providing an even pattern of dashes rather than the awkward junction you normally get at the beginning of each separate object. To join two objects together, press the mouse on the first object and hold the mouse down. Drag to the second object and release the mouse button. The two objects must have exactly matching ends or the Join tool will not operate on them.
