perfect polygons?
hi, I'm trying to make a perfectly symmetrical hexagon with all six triangular divisions visible. do you need to make it as a path? if so, how do you close the path?

RE: perfect polygons?
Yes, better start with a path. The very easy solution to create a regular polygon is to install this script: http://registry.gimp.org/node/59 (and then "Filters/Render/Shape paths/Polygon").

To connect two points (and close a stroke if these two points are the ends of an open stroke):
  • These must have 0 or 1 connection to another point (ie they must not be already connected to two points)
  • Select on of the point (click on it if not already selected)
  • Depress and hold the Control key: the pointer gets a "Forbidden" sign
  • Move the pointer near the other point. When close enough, the "Forbidden" sign should be replaced by two intertwined circles.
  • Click then to connect these two points
  • Release the control key

As well as the above, there is also the gimp gfig plugin in filters -> render.

I have never been able to produce correct results with GFIG. Even with a 1% brush spacing, GFIG (left) is not as clean as Path + stroke (with same brush at the standard 20% spacing)(right).

And with shape-paths you get a nice clean selection from the path if needed.

To complement what I have said:

1) use shape-paths to create the "empty" hexagon
2) add 3 "diameters". Adding them isn't difficult is you start by creating them not exactly on the hexagon, and then dragging their ends to the hexagon corners (use 800% zoom for accurate positioning).
