CPLofPLcontour
by Tim C. Lueth, SG-Lib Toolbox: SolidGeometry 5.6 - CPL/Closed Polygon Lists
Introduced first in SolidGeometry 4.7, Creation date: 2019-06-18, Last change: 2025-09-14
Converts a PL into a CPL, if the distance of last point and first point is below a threshold
Description
This function closes a PL to a CPL if the distance between last and first point is below a defined threshold, otherwise a CPL around the PL is created. In this case the threshold is used to define the tickness of the contour along the path
Auxiliary function originally designed to compare the area of contours, independed on closed contours or open contours

Syntax
CPL=CPLofPLcontour(CPL,[s,edge,caps])
Input Parameter
CPL: | | Closed Polygon line or Point List (separation by nan is possible) |
s: | | threshold in percent if <.5 or absolut if s>0.5 |
edge: | | treu=round edges; default is false |
caps: | | treu=round caps; default is false |
Output Parameter
Examples
CPLofPLcontour(PLcircle(10,'',pi/2*3.5),.05);
CPLofPLcontour(PLcircle(10,'',pi/2*3.5),7); % Still a path contour
CPLofPLcontour(PLcircle(10,'',pi/2*3.5),8); % Now considered as closed surface
