Hi all,I got the following code: print "ell circle 1"p1= Point(Rational(str(-351)), Rational(str(-2)))eci1=intersection(Ellipse(p1, Rational(str(50)), Rational(str(100))), Circle(p1, Rational(str(786959127181/10000000000))))for p in eci1: print "Point ",pprint "ell circle 2"p2=Point(Rational(str(0)), Rational(str(0)))eci2=intersection(Ellipse(p2, Rational(str(50)), Rational(str(100))),Circle(p2, Rational(str(786959127181/10000000000))))for p in eci2: print "Point ",p If you run this code you will notice that the intersection points are similar in both the intersection:ell circle 1Point Point(-2*2937**(1/2)/3, 32*42**(1/2)/3)Point Point(2*2937**(1/2)/3, -32*42**(1/2)/3)Point Point(-2*2937**(1/2)/3, -32*42**(1/2)/3)Point Point(2*2937**(1/2)/3, 32*42**(1/2)/3)ell circle 2Point Point(-2*2937**(1/2)/3, 32*42**(1/2)/3)Point Point(2*2937**(1/2)/3, -32*42**(1/2)/3)Point Point(-2*2937**(1/2)/3, -32*42**(1/2)/3)Point Point(2*2937**(1/2)/3, 32*42**(1/2)/3) it seems that the intersection is made like the two entity are centred in the 0,0 coordinate.It's a bug or it have to work in this way ?
