Re: Removing segment hard-coding

Hi Seth,

If we need to store the value to control plotting as part of board
settings (option 2), which makes sense to me, what is the advantage of
storing a different value in user settings (3)?

Hi Jon-

If there is a mismatch between a computer's video capabilities and the size of the board being created, the user could work on the board in a lower resolution and then output a smoother gerber (that is consistent across computers). This is how Solidworks handles 3d graphics.

This doesn't affect things like circles/tracks that use defined primitives in gerber output. It only affects interpolated edges in polygons. For other interpolations like rounded rectangles, we already use a higher (64) segments-per-circle count for the approximation in the output than we use for the on-screen representation.
