    Enhancements/Additons:

    • Modifications to insure that the minimum number of segments on a curve or loop set by min_nseg and min_nseg_loop is not limited my the minimum spacing set with min_scale and ref_len.


  • 05/01/20 RELEASE VERSION 1.19.15

    Enhancements/Additons:

    • Modifications for surface based background interpolation of length scale.
