Hi Dan,

How did you managed to fix it?

Hi Guys,

I had exactly the same problem which affected circles over a certain size. In part it is due to floating point errors in the maths processor.


The solution is to modify the post so it interprets the arcs differently. I must admit to not doing this myself but those good folks at Dolphin modified the post for me, in a matter of minutes.

I have the new post if you need a copy.

BR,
Windy.
