The offsetmethod command specifies the offset algorithm that will be used by default to shift curves.
offsetmethod is a command that applies to all curves produced by offsetting with the offset command. It is followed by a single argument, noted f:
offsetmethod f
where f specifies the algorithm used to eliminate crossings between the segments linking homologous points on the parent curve and on the offset curve. f may take the value 0, 1, or 2.
Full information about the effects resulting from the choice of one algorithm or another may be found in this section.
