I successfully used the filledCurveToPolygons3D function to create Graphics3D text in MMA 9 on a Windows 7 PC; see:

How can I create a 3D FilledCurve object?

However, when I installed MMA 10 on this very same machine and tried using this technique again, all the holes in the text are filled. I tried using the recommended changes to the RHS of processHoles that another user had had with MMA 9 on a Mac, but I still ended up with all the holes filled. The same problem shows up as well with the 2D function filledCurveToPolygons.

I believe this should be a comment below the answer by @SimonWoods linked above. But I can confirm that this is indeed a new issue in MMA 10 (Mac OS X here). –  Jens Aug 19 '14 at 5:10
The InPolygonQ function has moved in version 10 to Graphics`PolygonUtils`InPolygonQ. With that change it should work properly. –  Simon Woods Aug 19 '14 at 19:35
It does work properly. –  JohnS Aug 20 '14 at 17:18
