I have a part that I need to engrave (extrude cut) a lot of text. I keep getting zero thickness error but I can't figure out where. Help?

I use a lot of text in sketches and have found that some fonts with certain characters will cause the zero thickness error.  You can fix this sometimes by increasing the spacing between characters or changing fonts. 

Also, this is a complex sketch with a lot going on.  I would break it down into a minimum of 3 sketches with the first being geometry only then inner and outer text being in 2 additional sketches.  This will help you narrow down exactly where the error is.  Text features rebuilds really slow so when I get them working correctly I suppress them to speed up assemblies and rebuilds but leave the geometry features (lines, circles) unsuppressed.

Hi Angie, that is a lot of text! In my opinion some of your text is right on the edge of an existing edge (extrude cut) and that is why you are having trouble with your extrude cuts. See the bottom of the "T" and the "A"

Also take a look at your cut-extrude3 it cuts down into the part

Delete the Groove Cut not the sketch then Cut Extrude your Text and then cut the grooves, when you first cut your grooves there are lots of areas in the text that are messing with the Zero Thickness Error.

Good model little bit of time for the extrude ..
