Bob, Welcome
Try reducing in .25 increments (SU model) Line Wts, untill you are somewhat satisfied.
EX; 1.0......then 0.75..........then 0.50
I find there are no hard and fast rules here, because of paper size...scale...etc.
Shape Style tab has a line wt setting as well.
EDIT:
Wooops...Almost forgot,
You will need to "trick" LO to get the line Shape Style to accept a decimal.
As Follows...Draw shape......Select Shape.....Select 0.5 from the dropdown....triple click to the right of the decimal....enter desired #
Best,
Charlie
