Difference within Hatch Commands

[rcb007]

I am playing around with 2022. I am trying to understand what the differences between these commands for hatch. If I type "H" at the command line it gives me a different command line menu then the others. 

 

I have a profile view with a pipe network and profile, the (-hatch and -bhatch commands) cannot find a closed area from those objects when picking inside that area. However, using the default "H" seems to work like it should. I was hoping to use that command to replace my following code.

(command "-bhatch" "a" "a" "n" "" "p" "ansi31" "30" "0")
(while (= (getvar 'cmdactive) 1) (command pause))

 

Thanks for the pointers!
