1. A concise explanation of the problem you’re experiencing.

Hi sir, I am trying to draw the polyline using the mouse handlers over the terrain loaded globe. While drawing the polyline the line is going under the terrain and sometimes not visible. Once i completed the drawing it is becoming transparent. How to make the line transparent while drawing also.

2. A minimal code example. If you’ve found a bug, this helps us reproduce and repair it.

shape = viewer.entities.add({

polyline : {

positions : positionData,

width : 3,

material : new Cesium.PolylineOutlineMaterialProperty({

color : Cesium.Color.YELLOW.withAlpha(0.7)

}),

depthFailMaterial : new Cesium.PolylineOutlineMaterialProperty({

color : Cesium.Color.YELLOW.withAlpha(0.7)

})

}

});

Can you post a full Sandcastle example I can run? Are you saying the polyline appears with the correct color only when it is static? Are you using a CallbackProperty to make it dynamic while drawing?

A picture might also help.
