ODB++ Symbols

Symbols are primarily used to draw pads on the PCB. Hence they correspond to RS274X flashes. There are a large number of "standard" symbols which are controlled via their parameters. Symbols can also be built up from primitive drawing elements: lines, arcs, polygons, surfaces and pads. The RS274X converter supports both types of ODB++ symbols.
