Softening of Upper Corners of Bracket Toes

All standardized bracket toes (except the "Variant" versions of toe types 131-136) have a knuckle at the upper end of the toe. An option has been implemented to soften this knuckle by a fillet arc with a given radius. This option may insert a fillet arc in all bracket toes with knuckles except in the toe types 11, 12 and 14.

Normally the parameters of bracket toes are controlled individually by the External Bracket Set-up facility. However, this feature is controlled by the default parameter BKT_TOE_FILLET. If given this feature will be applied to all brackets with the relevant toe types. 'All' includes also panel brackets: If a part of the outer contour of a panel bracket is identified to be like a bracket toe (and shorter than 50 mm) it will be softened in the corresponding way.
