I wonder if it's because the sketch is mapped to a primitive Box.

I just reproduced this example with a padded rectangle and it works.

it actually has to do with the placement of the box. For some angles the groove succeeds, for other angles it fails.

Its a problem of the sketch shape being coincident with the face of the box being sketched on. If I move the sketch shape just by 2*Precision::Confusion() vertical to the face, everything is fine (except for a performance penalty which doesn't occur if I move by 1 unit instead of Precision::Confusion())

But IMHO its not an option to move the sketch shape. It is not the user's intent and might give unexpected geometry (especially if moving by a whole unit).

Interestingly, the problem also occurs even with the symmetric option, when the sketch shape is rotated away from the face of the box!

This problem is solved after moving PropertyFloat to double precision
