I thought this post by @Wayne_Friedt would add value to the 3D Printing Group. You may also be able to chip in with more info/advice.

Is an stl file universal. Can the stl file be opened by most any cad program that works with stl’s or that can export stl’s?
Example: a file from Openscad export to an stl. Then i try to reopen that stl file in Autocad2013, 123D Design but says file is not supported. Seems this is not the way to do it.
