copying linetype unsuccessful

when copying a lintype from one drawing to another the scale is different. For example the hash symbols on a Pneumatic Line are a lot smaller and fall below the line as seen below.

I've checked all of the Linetype variables match in each drawing

LTSCALE = 1.0

CELTSCALE = 1.0

PSLTSCALE = 1

MSLTSCALE = 1

and purged the linetypes and re-copied it.

Any suggestions?
