AS I saw your previous post at ACAD forum ,  I will upload what do you want to do. 

 

A sample DWG is the better way to get help.

A Hatch pattern definition cannot include linework and  a background fill and  separate little gradient fills inside the slots.  And it can't change among three  slot sizes and spacings within a single drawn pattern, if that's what you're asking.  And its linework can't contain actual curves, but must be made up of straight pieces.  So even if you want something more realistic, such as three different slot-outline-only patterns for the different sizes/spacings, the best you can hope for would have slot ends something like this:

SlotEnd.PNG

That end is half of a 16-sided Polygon -- it could be more and shorter segments, to look closer to  round, but the more there are, the more complicated the pattern definition becomes.  And the polygonal end cannot be truly regular, nor even the same for all three patterns, because of the nature of how the offsets between slots of the different sizes/spacings would need to be accounted for in the definitions.

 

So to have everything shown in your sample drawing, you will not be able to simply use a Hatch pattern, but may be stuck with copying the individual pieces around and editing to different outlines with Trimming, etc.

Kent you are correct about the hatch needing straights for the curves this exact problem was answered over at Cadtutor with some different hatch pattern generators being suggested to make slots with gaps. It was to create single row slots for a particular steel product. https://www.cadtutor.net/forum/topic/70417-make-pat-files/?tab=comments#comment-565391

 

 

 

The other way of course is to draw slots in a repeating pattern.  Dynamic block comes to mind.

You may also be able to use SUPERHATCH.

@Kent1Cooper @devitg is there a way of having just the hatch that is gradient hatch ? 

I will modify it with scale to have it almost the same 

thanks

There are 2 posts running for this in other post posted  a staggered array code written to do just this type of pattern.
