How to export the Properties‘ data?

[Wayne1407]

As you can see in this picture, I want to make an extension which can display the collected Mesh’s information in Properties, like the coordinates or the distance from other object.
The question is that I don’t know which parameter is what I want and which function used to exported it, is there some documentation? Or someone give me a script example?

HI @Wayne1407!

I’d recommend starting with the USD DLI course to learn more if you haven’t delved too deep into USD yet: Courses – NVIDIA

As an easy way to get started, you can hover over the property labels to get their USD attribute names.

When you’ve identified a property that you want to query, you can do something like this:

import omni.usd

stage = omni.usd.get_context().get_stage()
light = stage.GetPrimAtPath("/World/defaultLight")
# Get and print the "Rotate" property values
print(light.GetAttribute("xformOp:rotateXYZ").Get())
# Get and print the "Color Tempterature" property values
print(light.GetAttribute("colorTemperature").Get())

Thank you very much, and I will learn more through the Courses!
