For the sanity of CNC Cut File producers, a fundamental change in the way the text is exported throughout Inventor is needed... or I suspect a lower overhead approach would be a ’convert text to sketch geometry’ tool would suffice. It would only need to support single line fonts.
That would then deal with the arc aligned text problem, which you can't currently export at all via the IDW > AutoCAD DWG method. Multi-outline font (Normal fonts) requirements can currently be achieved using the emboss tool, which is only appropriate for decorative font machining.
This could then be automated as part of the Flat Pattern Export idea @BLHDrafting has submitted here.
Currently HSMWorks for SolidWorks can engrave single line text... the workflow to achieve a similar result in Inventor is far too convoluted. Having a decent solution for this in Inventor is long overdue and now blatantly obvious with the advent of Inventor HSM.
