Hello,

Lets say I have given object(for example 3d building) in czml:  
{  
&nbsp;&nbsp;&nbsp;&nbsp;"id":"somename",  
&nbsp;&nbsp;&nbsp;&nbsp;"availability":"2008-01-01T23:00:00Z/2008-01-02T23:00:00Z",  
&nbsp;&nbsp;&nbsp;&nbsp;"vertexPositions":{  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"cartographicDegrees":[  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;...positions(with nonzero-z)  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;]  
&nbsp;&nbsp;&nbsp;&nbsp;},  
&nbsp;&nbsp;&nbsp;&nbsp;"polyline":{  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"color":{  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"rgba":[  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;255,0,0,255  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;]  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;},  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"outlineWidth":0.0,  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"width":1.0,  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"show":true  
&nbsp;&nbsp;&nbsp;&nbsp;},  
&nbsp;&nbsp;&nbsp;&nbsp;"polygon":{  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"show":true,  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"material":{  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"solidColor":{  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"color":{  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"rgba":[  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;255,255,0,255  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;]  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}  
&nbsp;&nbsp;&nbsp;&nbsp;}  
&nbsp;&nbsp;}

But the effect I get is that only polylines get proper height, polygon seems to be glued to the surface, its totally flat. Is there a way to write in czml 3d object?

Best regards.

The feature is in b26, you need to update your CZML to take advantage of it. See [https://github.com/AnalyticalGraphicsInc/cesium/wiki/CZML-Content#wiki-polygon](https://github.com/AnalyticalGraphicsInc/cesium/wiki/CZML-Content#wiki-polygon)
