Hi Jason,
Thanks for this, I've just had a play with importing different coloured layers, and it works well from Serif Drawplus X6, but, so far, less well from Rhino 4, but it is useful to know how to keep things separate in Studio. Inkscape would be great if one could programme all functions of the Silhouette, including cutting force, directly, but I gather this is not possible.
Studio does open and close quite happily, and only seems to 'hang' during the shutdown process - not really a problem - as long as it gets no worse.
I use Rhino chiefly because I have been designing for Rapid Prototyping/3D printing and have just got used to this way of working. I am lucky enough to have a 3D miller (Roland MDX500), but the simplicity and convenience of the Silhouette on the desk is very attractive - and it is a lot easier to programme, although not quite as easy as a Stanley knife, Allan - but in my hands probably safer!
