So I guess I need to change the Arc object to store the angles

A gentle very gentle curve would require more, but certainly the above

doesn't indicate if the angles are fixed point, one degree resolution
or something better (floating-point).
is there a better way to represent arcs for pcb?

Is there any way to get better resolution? One degree is 25 mils at my radius.

Of course! Just rewrite those parts of PCB that deal with arcs.

Hi Mark,
There is a full bridge rectifier symbol (diode-brideg-1.sym) living in the
diodes directory.
Hm.
How can I make this netlist as four separate components?

I have written a Python script to do free rotation of gschem symbols,

Hi,
When drawing a bridge, such as a Wheatstone or full-bridge rectifier,
it is traditional to draw the symbols as a 45 degree rotated square.
How is this accomplished with gschem?
