you're in luck (you caught me on a Friday) r5196
should now work. Still a bit to do - only works for projection plots at present, but should be enough for what you need. And 3D iron filings plots work :) Daniel > On 7 Nov 2014, at 9:58 am, Benjamin Lewis <[email protected]> wrote: > > [Apologies for top posting] > > Any way I can shoe-horn this into working for now?
