Umm.. did I say I'll knock one out.. ? I even set my plate down to respond... tell you enough? If it pleases you I'll throw one at lunch in your email. (dxf - 2000 compatable as most machines like that version)

Oh.. and when drawing it and saving as a dxf.. Autocad could care less how thick it is...

And as a bonus feature.. I could go ahead and spend an extra 5 minutes (older quad core processor ) and send you the Solidworks file for your viewing pleasure where thickness will be included.. Hope your at 2012 version.
