Settings are as program installed and not changed, i.e.
Setup and Fabrication Level is set to Proportional.
Terminals
Throughhole
Lead Widith <= 0.4 mm
Lead Width > 0.4 mm
In both cases, User and Default Courtyard Excess is equal to 0.25 however no courtyard excess is applied to a axial resistor I tested and courtyard matches 3D body outline.
Withouth changing the "user" setting, i.e. as program is installed with all default .dat files:
If Setup > Fabrication Level is set to Level A then:
Terminals
Throughhole
Lead Widith <= 0.4 mm User = 0.25 and Default = 0.50
Lead Width > 0.4 mm User = 0.25 and Default = 0.50
(should user here, above, default to 0.5 to begin with before the user alters it?)
If Setup > Fabrication Level is set to Level B then:
Terminals
Throughhole
Lead Widith <= 0.4 mm User = 0.25 and Default = 0.25
Lead Width > 0.4 mm User = 0.25 and Default = 0.25
If Setup > Fabrication Level is set to Level C then:
Terminals
Throughhole
Lead Widith <= 0.4 mm User = 0.25 and Default = 0.25
Lead Width > 0.4 mm User = 0.25 and Default = 0.25
(should this be 0.1 mm or has IPC-7251 changed for new revision? Tom's presentation shows SMT courtyards but not through hole specifically)
I would expect Proportional to have a courtyard excess of some value and the "proportional" only to apply to the pad size. Personally I don't use Proportional but always create A and B levels.
