Gap detection highlight command?

[rock1]

Is there a separate gap detection command in autocad that highlights tiny gaps of closed polygons? I render my drawings in photoshop and often there are small gaps that appear in my work or the work that I get from others. Right now only hpgaptol and using hatch command highlights the small gaps.

Here's a LISP routine to mark gaps: GAP

 

Here's an Autodesk discussion on the topic.

 

Both found by googling "autocad gap detection."

I just tried on the following drawing. I set the gap limit to 0.5.

 

The gap is almost 0.2 but still goes undetected. I'm using Autocad 2020.

My first guess was that, once the routine found a match, it went on to another point. But after looking at the code, I believe it takes care of that potential oversight.

 

I opened your drawing. Maybe it's my units setting, but when I measure that gap, it's 1.66. That's outside the tolerance, so it wouldn't be flagged.
