A couple of years ago I outlined some of the issues encountered by Revit users and how that can be addressed by setting line types to object categories. E.g. Adding centrelines to pipework and round duct.
There is often a desire, for continuity to ensure that these line styles look the same or as close as possible from previous CAD software, often AutoCAD.
AutoCAD holds line styles in a text file, which are normally held in a drawing template and set to layers and styles as appropriate. The positive values indicate the length of dash, negative value the size of the gap.
In the listed example there is a 15 mm dash, a 6 mm gap with a 6 mm dash with another 6 mm gap. This pattern is then repeated.
In Revit, the line pattern is also ideally stored in the template and can be accessed from the Manage >>Additional Settings>>Line Patterns. This is all achieved via a dialogue box rather than a text file.
