Variable

Description

ext_pad_ratio

This ERF variable enables you to calculate the extension point according to drill and pad size.

Prior to Genesis version 8.1b, the extension point was calculated according to the following formula:
ext_point = line_width * td_ext_ratio + td_ext_add

From Genesis version 8.1b, the extension point calculation formula is:
ext_point = line_width * td_ext_ratio + pad_size * ext_pad_ratio + drill_size * ext_drill_ratio + td_ext_add

If you wish to use the old formula, the new parameters should be set to 0 (their default value).

Note: For rounded teardrops, the distance between the extension point and the pad center cannot be longer than the value of the pad radius.
