I got a zero-thickness error when trying to cut-extrude a
sketch, but I cannot find the area of zero-thickness. Is there a
way to detect the area of zero thickness in a sketch?

- Sketches don't have zero thickness, the resulting solid is the problem.

Adjust some of the dimensions to make them overlap more with the solid body. Or try changing the length of your extrusion. Normally a few thousands will fix it, or you will at least find out where the error is and adjust accordingly.- Aside from checking and adjusting 134,000 different points on my sketch is there a way to detect the area that is generating the zero-thickness error when I use the sketch to create a cut?
- If you have 134,000 points in your sketch, you have problems none of us can help you with.

If you want to check for places where an extrude or cut feature might create a zero thickness condition, extrude the feature as a separate body (uncheck the Merge Result box), and then look for a point or edge on the new body where the point or edge intersects a face. There are probably other situations that can cause zero thickness, but these are the easy to define ones.

Of course you get better help if you provide a picture or a model.

Best of luck.

There is not a "Zero Thickness" Detection Tool.

You may want to try using; Tools - Sketch Tools - Check Sketch for Feature.

Side Note:

Two definite cases where this error will occur:

A sketch with a corner or point that is coincident with an edge.

A sketch with an arc that is tangent to an edge.
