I have created a PolylineZ feature class, but I don't know how to set the Z unit.
I added this PolylineZ feature class to my map, and when I look at the layer's properties, the source has "vertical units" of "foot_us." How do I set this attribute when I create the feature class?

I had tried setting the layer's Z unit programmatically when I create the layer from this feature class, but it didn't seem to do anything. Here's the code I have:
var layerProps = newLayer.GetDefinition().Layer3DProperties;
if (layerProps != null)
{
Unit verticalUnit = ...// retrieve the Z unit (will be feet)
if (verticalUnit != null)
{
layerProps.VerticalUnit = verticalUnit;
newLayer.GetDefinition().Layer3DProperties = layerProps;
}
}
