3D Model - Sketch Line Style

Refer uploaded image - I want to change the line style of CTRLFONT_S_L, L_L, S_S, PHANTOM_S_S. 

All these lines are appearing change in the model. so i want to modify the line length so that i can differentiate the lines in my diagram for different pipe sizes/colors.

Basically i need additional line styles to differentiate all my pipes/tubes in the plumbing diagram.
