Version: 0.90.0 (using KDE KDE 3.97.0) Installed from: SuSE RPMs OS: Linux I constructed the inner circle of a triangle and another triangle, defined by the intersections of the circle and the angle bisectors of the outer triangle. I changed the outer triangle by moving one of its points. Depending on the position of the point the inner triangle is sometimes drawn correctly, sometimes only partly, sometimes not at all. I will attach two screenshots showing the difference between the expected behaviour and the bug.
Created attachment 22755 [details] kig drawing objects correctly
Created attachment 22756 [details] kig drawing only parts (of the inner triangle)
This happens because the intersection between a segment (any of the triangle sides) and the circle is not really perfect, and there's that small delta that makes the intersection point invalid.
There is a program which can handle these deviances: http://geonext.uni-bayreuth.de/ It's written in Java and it's Open Source (GPL).
