In drafting mode, i want to set linetype scale for Normal Line, Hidden Line, Center Line.

many time after taking printout of draft file, hidden lines does not look like same & because of that problem occoured.

Solid Edge v20:

1. You can change the lines generally from Format -> Style.

2. You can change the displaying of your drawing to “as printed” (and to see how it will look like when printed) from Tools->Options->View->Display as printed

The same things in  Solid Edge ST3:

1. View->Style

2. Application Button ->Solid Edge Options->View->Display as printed.
