Pen style or line thickness in draft

Dear Team,

How to set up different pen styles are different line thickness in draft for different lines.

Thanks in advance

There is no user interface for that.
You need to use the Command Window.
i.e.:

NEW STYLWL
NEW LSTYTB
NEW LINEST

Then you can set/change the attributes:

LWIDT 2.5
PATNAME SOLID

If you are using PDMS you can read Draft User Guide Chapter 8.2.2 User-Defined Line Styles
