If you need additional linetype for a drawing you can follow the steps below
- Type in LINETYPE in the commandline of your AutoCAD Civil3d
- Click on the load button at the top
- Then click on the file button at the left top.
- Once you have got this far you now need to navigate your way to C:\ProgramData\CSS\Stringer 20??\ADITCAD folder shortcut/aditcad and find a file name Stringer.LIN which has all different line types in there for you, select it and click Open.
When you go back to the previous screen you need to select a linetype from the list and then Select Control A on the keyboard (this will highlight all linetypes in there) then click OK and all the linetypes will have been added into the drawing.
Hope this is helpful
