Have Problem to drap a network dataset on a DEM or 3D model. :(

Hiii Everyone...!

I've created a complete network dataset and now I want to drap it on a DEM layer or a 3D dataset, but it's not succeeded and found a rigorous problem in this work.
Can anyone help me in this problem??

Aman,

Can you describe what are you trying to achieve? Is this for visualization? Is to create 3d networks?

And when you say:
"but it's not succeeded and found a rigorous problem in this work"

Can you say what you tried and problem did you find?

Regards,
Jay Sandhu

Thanks for your reply sir,

Actually I have a network dataset but it doesn't have z value to visualize it in 3D environment, so I want to drap it on DEM layer to visualize it in 3D environment. At this point I want to ask you, is it possible to drap a network dataset (without z value) on a DEM layer of the same area.

If is it possible then please do help me in this problem.

You can "drape" the road feature class that makes up the network dataset and convert to 3D.
And then you can build a network dataset from it.

For converting 2D data to 3D, see the following:
