# Change the soldermask and polygon clearances for selected objects.
#
# This test operates on clearance.pcb. This file should be saved with the
# soldermask layer enabled and two of four columns of pins/pads/vias
# selected.
#
# This test has three parts:
# * Part 1 sets the clearance to a specific value
# * Part 2 sets the clearance to zero
# * Part 3 sets the polygon clearance to something small, so as to invoke
# the minimum clearance as defined by the DRC rules.

# Initial revision.
#
#
# PART 1: Set the soldermask and polygon clearances to specific values
#
# Set the SM clearance to non-zero
ChangeClearSize(Selected, 0.5mm)
# Turn the SM layer off so ChangeClearSize will affect polygon clearance
Display(ToggleMask)
# Set the poly clearance to non-zero
ChangeClearSize(Selected, 0.5mm)
SaveTo(LayoutAs, clearance-non-zero.pcb)
#
# PART 2: Set the soldermask and polygon clearances to zero
#
# Set the poly clearances to zero
ChangeClearSize(Selected, -1mm)
# Turn the mask back on
Display(ToggleMask)
# Set the SM clearance to zero
ChangeClearSize(Selected, 0)
SaveTo(LayoutAs, clearance-zero.pcb)
#
# PART 3:
# Set the polygon clearance to something small, which will enforce a minimum
# clearance. Solder mask doesn't have this enforcement. This test may need
# to change in the future if the enforcement changes as I'd like it to.
#
# Turn the mask back off
Display(ToggleMask)
# Set the poly clearances to the minimum value
ChangeClearSize(Selected, 0)
SaveTo(LayoutAs, clearance-min.pcb)
# Note: If the script is to be used in conjunction with an exporter, then
# Quit() should not be called. If it needs to be used both with and without
# an exporter, then add --action-string Quit() to the invocation for the
# script only test.
Quit()
