I take it you got the ones from me?
If you need more from CADSTAR let me know.
Have you also catered for drill files?
You could also work on the IPC2581 format and be the first to release the android viewer for that.

There are a couple of PC viewers for 2581 xml format now but thats about all - so its a developing market.
I suppose that there could be a use for it, although if you can charge for it - I doubt it as GC-Prevue etc are free for on the PC so who’s going
to pay to mess around putting it on a phone or tablet?
I suppose someone who travels for hours by train and may want to check them while travelling…
