VLui
by Tim C. Lueth, SG-Lib Toolbox: SolidGeometry 5.6 - Auxiliary function
Introduced first in SolidGeometry 1.0, Creation date: 2012-07-25, Last change: 2025-09-14
returns a vertex list drawn by the user in a plot window
Description
New points are set in red. Finally all are rounded to the given resolution and plotted in blue.
Since rel 4.5 it is also possible to
- insert points on lines
- deleting points on lines
- pull points on lines
- edit existing vertex list
- edit existing polyshapes
Left Mouse button => Set remove and shift points by
Right Mouse button => Shift at edges, Rotate at corners
Middle Mouse Button => exit
