Open document: Opens the referenced file in order to modify the PHX structure.

Mount fully: Mounts the full PHX, with its geometries, joints, rigid bodies, and embedded devices.

Convert to static: For static mounting. The simulator will deletes joints, rigid bodies, and embedded devices.

Disable contacts: Turns off contact handling for all referenced physics geometries.

Disable Shadows: Turns off the shadows for all geometries in the file.

Anchor size: Sets the size of the PHX representation square in the world. This size setting is for visual purposes only and has no effect on the simulation.

Mass: Indicates the total PHX mass.
