ive dajusted the battin style to show between 25-100MM batting insulation in my drawings.
code is as follows for batt insulation in a 1:50 scale dwg
*100mm_INSULATION,100mm Insulation SSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSS
A,0.0,-0.25,[BAT,ltypeshp.shx,x=-0.25,s=0.25],-0.50,[BAT,ltypeshp.shx,r=180,x=0.25,s=0.25],-0.25
note: using the batt linetype can cause some problems - i tried using it, and a problem occured when psltscale=1, and autocad scaled the linetype up the same in different viewports example, 100MM batt insulation in 1:50 viewport plotted in pspace at 2mm (correct size), 100mm batt insulation in 1:5 viewport plotted in psspace at 2mm (incorrect size - should be 20mm).
using the batt linetypes are only good if you individually ltscale the line entity on a multiple viewport drawing
