how do i change the number of vertices on the polygon tool?
Polygon drawing tool
Polygon drawing tool
POLYGON is a drawing tool capable of drawing arbitrary polygons with three or more vertices.
Polygon configuration panel
Prior to version 2013.1, there was no configuration panel for Polygon tool and the drawing always started with a triangle. Since version 2013.1, users can select one of eight possible starting shapes:
How to use the Polygon tool
With the Polygon tool selected, click and hold left mouse button down while moving the mouse to create the initial polygon.
After you release the mouse button, control handles appear. You can move the control handles to move polygon vertices or to split polygon edges. Dragging one vertex control handle on its neighbor merges the two handles and removes the edge between them.
If the created polygon is in a vector layer, it can be scaled and rotated by holding down a SHIFT key and dragging it with mouse. It may also be converted to Shape from context menu and then further refined.
Scripting parameters
POLYGON tool can be used from scripts. The command in script must have the following arguments:
- coords - pairs of floating point numbers representing vertex coordinates. There must be at least 6 numbers to define X and Y coordinates of three points.
Example
DrawTool.POLYGON(Document, 50, 10, 90, 90, 50, 70, 10, 90);// draw a circle section (2/5 of full circle) (center is at [100, 100], radius is 50)
var coords = new Array();
for (i = 0; i <= 20; ++i)
{
coords[i+i] = 100+50*Math.cos(i*2*3.1415/50);
coords[i+i+1] = 100+50*Math.sin(i*2*3.1415/50);
}
DrawTool.POLYGON(Document, 100, 100, coords);See also: DrawTool object, Document object

Drag one of the green points to split an edge. Drag one of the blue ones over its neighbor to delete an edge.

You got to be kidding me! Don't want to sound offensive, but doing it this way makes it impossible to have symmetrical polygons. If I want to draw a hexagon, I generally want all the sides to be the same length. Are you saying that I have to adjust the length of the sides "visually"? I like the program very much, though, and I won't be using the poligon tool much anyway.

This is the one and only thing I hate about real world paint. Draw a perfect triangle, but you are on your own for any other shape - like hexagons.
