D

pygerber.nodes.d_codes.DNN module contains definition of DNN class.

D

Bases: Node

Base class for all Dxx commands.

is_standalone class-attribute instance-attribute

is_standalone: bool = Field(default=True)

Flag indicating if the node is standalone, ie. it is not prefixed with G code with no asterisk.

This is necessary as some legacy Gerber files use redundant G codes to prefix pretty much every D01/D02/D03 command. To make it possible to keep the original layout of the file, we need to know if the D code was directly prefixed by such redundant G code.

Example:

G70D02*
G54D16*
G01X5440Y5650D03*
G01X5440Y6900D03*
G01X6800Y2200D03*
G01X5550Y2200D03*
G01X17720Y6860D03*
G01X17720Y5610D03*
