I'll give you something McWaters12, you are persistent
Do you have Civil 3D?
If you do first explode your polylines so that they become Lines
Then create a new Surface.
Go to the Prospector tab of the Toolspace.
Open up the Surfaces.
Open up Definition .
Right click Drawing Object.
In the Drop Down List Objects select Lines.
Select all your lines on screen.
On the Settings Tab open up Surface.
Open up Surface Styles.
If you have not created your own style then right click Standard and select Edit.
Go to the Display Tab and make visible what you want to see.
Other properties can be set in the various tabs.
I would not recommend editing ANY Standard Style, but first of all right clicking the Standard style and selecting Copy -give it your own name and then edit that style.
Post your drawing and say exactly what you want to do.
