Scale of Hatch Scale

I hope this makes sense but is there a setting which controls how hatch Scales are Scaled in the drawing?

just an example;

I have hatched a boundary and used a scale of 0.10 coz using whole numbers (like 1.00) as scale makes the hatch pattern too big.

is there separate setting that makes the 1.00 hatch scale size like the 0.10 hatch scale.

TIA

ive attached a sample of my problem. 2 hatch scales with all the same properties;

except they dont look the same.

I have similar problems with hatch scales like this one. but I just want to know if there is a variable that needs to be set for hatch scales

TIA

Anyone .

Problem is in MEASUREMENT variable.

nice tip,havent really wrapped my head around how it affects it, but yes, one is in english scale and the other in metric. i thought it would be a variable or something. tried the registry thing but its too deep to dig ^_^.

The trouble is that there are two Hatch pattern files, acad.pat and acadiso.pat which is 25 times the scale of acad.pat.

AutoCAD does not seem to be able to distinguish from which file the pattern came, so for the same named pattern, if both files are in the search path, you can have two different results, as you found out.

I think the only cure is to redo both hatches at the same time, then you know that the pattern spacing comes from the same file

yea, I switched the MEASUREMENT and matchprop one with the other. id better check on the acad.pat file on every computer to make sure they all use the same.
