Function

Reports unified lines (lines of more or less equal length on top of each other and nearly parallel, that are replaced by a single line). When lines are not exactly parallel they will still be replaced if the distance between them varies no more than v_parallel_to along their length. Lines have to run parallel to each other by at least v_min_projected_overlap of their length to be considered unified.

Known Limitations

Only pairs of good lines are processed. A line is considered good if it is:

*    A round aperture line

*    Untouched by negative features, not cut by rout nor drilled through by NPTH holes.

*    Long enough, where the ratio of skeleton length to the pp_given_width action parameter is greater than the v_min_len2width_ratio .ERF variable (see example below).

See example of line length criterion below:

v_min_len2width_ratio = 2.0

pp_given_width = 7.0

According to the above, lines with skeleton length less then 14 will be ignored.
