Welcome to RCSB jviss and thank you for the very kind words.  I am hopeful that 2016 will see some positive changes in my situation and I hope to be able to return in full force by year's end.  Of course I am still producing rivets in the meantime and would be happy to provide them for your Spitfire.  As for the other external details there may be solutions available, happy to discuss it.  Regarding the WW1 items I would not be averse to offering them if the market is there to support it.  However, my interest in that era is limited and, thus, so is my knowledge and library of research material.  I would actually love to do some dummy engines as well as machine guns, although I think it is possible that the latter is already being pretty well covered by other vendors.

I am strictly an AutoCAD user and a self taught one at that.  Thus I am sure there are easier and better ways of doing things but I usually can manage to get where I want to go.  I would like to get much more proficient using the 3d component of the software.  Matter of fact, I would like to eventually get a more powerful 3d software altogether but, for now, AutoCAD is more than I can handle!

    I am a ME CAD Designer and also a great fan of Autodesk i.e. AutoCAD fan-  If you're at all interested in more of a 3D application give "Fusion 360" a look it utilizes an AutoCAD based format but is a very easy and pretty intuitive program.  Also, in addition me being of Polish descent I appreciate the FREEBIE aspect for "Hobby or student applications".

Thank you for the heads up, I will give the Fusion 360 a close look.
