Entity Drawing Tool

Hi, the community!

I have just completed the entity drawing tool.
Demo Video


const viewer = new Viewer(“cesiumContainer”, {

viewer.extend(DrawingToolsMixin, {
createToolBar: true

Would be happy to hear any feedback.
And sorry for my poor English.
Thank you.


Hi Zhefeng,

This is awesome! Thank you for sharing.

Is the code open source/somewhere we can check out?
