Use contour lines from AutoCAD to create a height map that can be used in City Engine

Hello everyone,

I have seen in a tutorial that you can import a greyscale height map into City Engine and use it to drive development height in a city.

However, I usually have some AutoCAD data (or data under ArcGIS, which I guess would be much easier to deal with, but I hope to get a solution for AutoCAD too) with some contour lines (which I can know the height of). I don't know how to use these lines to create a greyscale height map in City Engine (or to create some other type of data which could be used as a height map in City Engine). Would someone have a step-by-step workflow for this question for AutoCAD and ArcGIS? That would be very helpful!

Thank you very much in advance for your help! (I guess that for ArcGIS I would first need to create a TIN from the contour lines, but I haven't done that for a long time so I'm not sure if this is correct...)
