Hatch spacing too dense, or dash size too small

"Hatch spacing too dense, or dash size too small" This is what I get when I try to hatch a large polygon in my drawing. I need a smaller scale on my hatch than AutoCAD will allow. Does anyone know how to change a setting that will let me hatch to smaller scales?

 

(defun c:mhatch ()

(setenv "MaxHatch" "1000000")

(prompt "\nHatch Density is set to a big number...Retry your Hatch scale")

(princ)

)

Try this

This bit o lisp bumps the MaxHatch var by 10,000 each time you run it. I
prefer this over a single increased value, as it lets you bump a little till
it works.

(defun C:MHU () ; Increment MaxHatch Environment Variable
(setenv "MaxHatch" (itoa (+ (atoi (getenv "MaxHatch")) 10000)))
(prompt (strcat "MaxHatch set to " (getenv "MaxHatch")))
(princ)
)

 

Gordon, why not just bump it to 1000000 once and be done?

 

My understanding is that the var actually allocates ram, so using a bigger
number than needed wastes ram. Probably a non issue really, but with an easy
way to bump I just leave it that way. Personally, I wish AutoCAD would give
the warning, then offer a button that just does the change, setting the var
to 10% more than needed. The fact that this has to be done 'manually' is
just lame. Same is true for the layer dialog sorting. It should just bump
MaxSort as needed, with a CAD manager controlled warning level and ceiling,
but beyond that just handle it.
Oh well.

Oh, okay, just curious. Thanks.

 

I take it you have never run into any issues with just cranking it up? The
other bummer is this is not a DWG based var. It would be nice to set the
value in templates, based on the kind of drawing. Elevation base files get a
high MaxHatch, sheet files get a low one, that kind of thing.

We crank the ram up every chance we get, most are running 2G, with the smallest 1G.

We set;
(setenv "MaxHatch" "100000")
(setenv "MaxArray" "50000")

in the startup lisp, and as yet haven't had any problems. But then again we don't use small hatches either, AR-CONC is about as fine as it gets.
