I recently started using DraftSight and have little experience with CAD systems.  My problem is that I have lost the line styles in the 'Model' world and on printing.  I am using the system to layout a new bathroom and want to show pipes and hidden detail.  I set the 'Options - Drawing System - Unit System - Unit Scale - Block Unit Format' to Centimeters and I think the 'Format - Line Style' Global scale and Entities scale were both set to 0.1 with 'Scale based on sheet's units' set to on (ie ticked).  I did something in format and now the 'Hidden', 'Center' and 'Dashed'lines only show as continuous lines in 'Model World' and on prints.  In 'Sheet World' the correct line styles are showing.

I've tried every combination of Global and Entities scale that I can think of but this makes no difference.

My operating system is Windows 7 Home Premium.

Any ideas what I can try to fix this?
