Tool to convert CZML to 3d corridor available?

Is there a tool which converts a CZML to a 3d corridor?

Context: If CZML is underground, lifting up the CZML an amount of meters like

does not satisfy.

I think that a prismatic formed corridor with a proper height that is pulled along a CZML based skeleton would be a better solution.

Thx in advance for your useful hints

Remark - this is a rather bad solution:

Remain the CZML as original “underground” and change the path to width 100 (example).

Reason: it looks bad because of the zig-zag of the CZML.

Can you describe a bit more what you’re trying to visualize? Maybe share a screenshot of your CZML file visualized in CesiumJS?

You could set an extruded height like in this example to extrude your corridor in 3D with CZML: https://sandcastle.cesium.com/index.html?src=CZML%20Corridor.html

Thx for your information. I will further use czml polylines although they do not clamp to ground.
Example:

My problem is solved for this time.
