Hello,
I like the work of Mr. Sol Amour (Will stop, he will think that I am a stalker)
+designscript guide
+I try to visualize and understand the scripts of Mr. Vikram Subbaiah
and so many other people (I absorb)
Here is a knowledge slider 
(
code block:
[Line.ByStartPointEndPoint(
Point.ByCoordinates(0,0),
Point.ByCoordinates(10,0)),
Line.ByStartPointEndPoint(
Point.ByCoordinates(0,-0.2),
Point.ByCoordinates(0,0.2)),
Line.ByStartPointEndPoint(
Point.ByCoordinates(10,-0.2),
Point.ByCoordinates(10,0.2))];
GeometryColor.ByGeometryColor(
Cylinder.ByPointsRadius(Point.ByCoordinates(0,0),
Point.ByCoordinates(Knowledge*10,0),0.2),
Color.ByARGB(255,0,255,0));
good evening
Cordially
