When I try to export a file to STEP format, that contains text objects on or embedded into a base object, only the text is included in the STP file. The base rectangle is excluded from the STP file.

Hi Don, what are you using to make the file, is it "File > Save As" or "File > Export" ?

The difference between these is that "File > Export" writes only the selected objects to the output file, while "File > Save As" will write everything regardless of selection.

So what you describe would be normal behavior if you had only the text objects selected and did a File > Export.

Please let me know if that doesn't explain it.

Thanks,

I had a defect in my file. It was not a full solid. I am sorry to have taken your valuable time for a dumbbell issue. My lesson is, don't report a bug when you are sick and exhausted, but keep working anyway.
Now that I am actually awake, I have a file that is working fine. Thank you so much for MOI.

Don
