gEDA-user: ElementArc

Hi,

I am making a base for a toroid transformer and I am using an element footprint as the basis for the design. I have used a spread sheet to calculate the mounting holes base on 120 degree spacing. I have three arcs between the tabs to define the outline between the tabs. Using the information from footprint creation last updated by Stuart D. Brorson 01/29/2005 it looks like the arc starts at 0 degree = 9pm and goes ACW not CW. I can live with that. Where I have a problem is starting the arc between about 330 and 359 degrees. It seems to be quite erratic. I have attached my footprint and a test footprint that I hope highlights the problem so that I can be helped.

Regards Ian.
