Fnct to create the crosssection contour using DIN13 for a thread

Description

This function is an extract of first SGthread function!
Attention: Every Pitch (also the one from DIN 13) will create overlapping facets if rotated using SGofCPLrota. The reason is the limited number polygon points of a circle or in this case a helix. This problem is solved in SGofCPLrota by default.

Syntax

[PLB,P,KD]=PLthreadDIN(D,[P])

Input Parameter

D: DIN diameter; negative values for nuts
P: optional pitch, otherwise taken from DIN13

Output Parameter

PLB: CPL for the cross section if the thread
P: Pitch of the tread
KD: Core diameter of the core of bold or nut
