In Symbol Editor, a customized symbol is a redefinition of an existing symbol. The first step in creating a new symbol is to decide on which symbol it is to be based. After you have established this basis, you use the Edit window to draw the shape of the symbol.
Edit Window
The Edit window consists of a drawing grid and a Preview window, located in the upper right-hand corner. Use the commands on the toolbar and the Symbol menu to draw and refine a symbol.
The Edit window also consists of several markers: a start point, an exit point, and, optionally, a spindle connection point. Each new symbol must begin with a start point, which is the first point that that Isogen uses when attaching pipe or other symbols to this one. Likewise, each symbol must have an end point, which is the exit connection point to which Isogen attaches pipe and other symbols. The spindle connection point defines where the spindle connects to the symbol.

A spindle connection point displays in the Edit window only if you specified a spindle SKEY in the New Symbol dialog box when you initially defined the symbol.
