Hi,

When I give height and extrude height same value it’s not working. Please find the attached sandcastle screenshots. Could you please let me know whether it’s bug or not?

Thanks,

Gowtham.

Hello,

Right now, each height is defined as relative to the earth. So if you want an extruded polygon with height x, you have to use

height: x,

extrudedHeight: 0.0

We have an issue written up to make the height parameters more intuitive. We eventually want to change it to work like you expected.

Best,

Hannah
