It does say something like that but it also says something bizarre like 4 axis simultaneous being in the extension. Quite why you'd get 5 axis simultaneous in the paid version and have to buy extensions for 4 axis is beyond me. I'm sure the prat who wrote it knew what he meant.

I forget the exact wording and I can't be arsed to follow the hullabulloo. However, the wording was as clear as mud (hence the comment) and I doubt I'd get any sort of answer if I asked. I may have to see about using DeskProto or FeeCAD at this rate. Let's see what we have when the storm has blown over.
