how to show sweep line in drawing ?

[ronfya]

Hello all,

My question is in the title of this topic.

I found this on that subject

but I can't get it right

... how do you show datum curves in the drawing ?

And it is said that

You can also change line type for datum curves shown on the drawing. This can be accomplished in the part (Modify>Line Style) or in the drawing with (Format>Line Style).

Why is line style greyed out then ?

Thanks for help.
