Usage guide for Compositing with Carbon Basic
Symbol Elements

Symbol elements are constructed from graphic elements and other symbols to form a spline/plot, which is simply a list of points connected by straight or curved lines drawn with different pens. Among the pens is the "invisible" pen to allow moving to a new point without drawing anything.

Once constructed a symbol may be used multiple times, thereby decreasing the time to create more complex drawings. Symbols can be resized, moved, and rotated like other graphic elements, adding to their usefulness.


To construct a symbol first open a blank composite of any size large enough to draw all the individual pieces. You may use any graphic element (see the previous page), but limit the composite to that of just one symbol as the process of creating a symbol gathers up all graphic elements in a composite. It is a good idea to save the composite that is the source of a symbol for later modification.

Using Symbols

Symbols may be added to a composite directly from their source composite or from a collection of symbols in a "library" composite. Library composites are built by adding symbols directly from source, so let's cover that method of use first.
While in the composite to receive the symbol click on File then "Symbolize", the following dialog opens up:
Navigate to the desired symbol source composite then click OK, the symbol will be generated and placed in the center of the composite. Note that symbols have names, the name is the same as the composite that defines the symbol. In the following screenshot we moved the symbol to reduce the size of the screenshot.
Note: If you select a gallery symbols will be created for each composite in the selected gallery and placed in the composite in a tiled manner to make locating each symbol easier. This is the easiest way to create a library composite after all the source composites have been defined.

Alternately from the source composite click on "Tools", navigate to and then click on "Make symbol, place - in another composite"
The symbols tree dialog opens up, navigate to the composite to receive the symbol then click OK.

As can be seen the symbol can also be added to the same composite or to the tote, which is useful for building up a symbol with repeated parts, such as the multiple turns of a coil, or the multiple diagonals of a resistor.

To import a symbol from another composite or library click on "File" then "Import Symbol", the following dialog appears:
Navigate to the composite containing the desired symbol, and then to the symbol itself. Select the symbol then click "OK"
