Interesting: when I reload all the linetypes from the stock AutoCAD iso.lin file all your linetypes disappear, in both files.
Changing the assigned LINETYPE SCALE of all the lines to 1 and lowering your LTSCALE from 1 seems to make both files behave normally.
Your 1st solution has worked, thanks! I will re-work the key so it uses the standard dashed linetype. The non-standard one must have been inheritted from some old drawing.....
Thanks for all your help guys......Gavin
The linetypes must have been take from an old drawing which used non-standard linetypes. I'll revert to the AutoCAD stock linetypes from now on and not bother you all again!!! Thanks for your help.......
