Starting with Isaac-sim

I have a very basic question regarding starting up with Isaac-sim, lets say if I want to model a camera/IMU sensor what would be the preferred way of modelling it, i.e., via GUI or extensions or standalone python scripts?

Any help would be appreciated.

Workflows — Isaac Sim Documentation provides an overview of how to approach different tasks within Isaac Sim, which should give you a good starting point for deciding how to best model your camera and IMU sensors:
