Hello,
I was wondering why the drawing tools would only let users choose integers – from 1 to 100 – for line width. After all, line width in KML is a float. I did some tests and found out that the rendering of lines is done by groups:
- 0 – 0.24999997 → no rendering at all
- 0.24999998 – 1.2499998 → rendering #1
- 1.2499999 – 1.2499998 → rendering #2
- 1.2499999 – 2.2499997 → rendering #3
- 2.2499998 – 3.2499998 → rendering #4
- and so on...

In my own opinion, any line that has a width above zero should be drawn. It should be:
- 0 → no rendering at all
- 0.0000001 – 1.2499998 → rendering #1
- 1.2499999 – 1.2499998 → rendering #2
- 1.2499999 – 2.2499997 → rendering #3
- 2.2499998 – 3.2499998 → rendering #4
- and so on...
Thank you !
P.S. : The KMZ I worked with is in the ZIP. You can see that the 0.1 and 0.2 width lines are not drawn.
