Crete Different Lane Width and Assembly

[srt_titya]

Hello all Autodesker, I have 2 questions in mind

1. How to create a different lane width? The lane width of the road is different.

2. How to show (render) different material in 3D? The Carriageway is Concrete and the Shoulder is AC.

1. Use a polyline or alignment at the edge of the lane, and then use a lane subassembly that allows targets. Pretty much anything but the Basic tab. 

2. Check out the Code Set Style. Change the Link style for the lane link code to be different from the shoulder link code. It's the Material Area Fill Style to control the plan display.
