Variable bindings on objects

The Variable Bindings section of the Objects panel is where geometry meets logic. Each of the nine pose axes, position X/Y/Z, rotation X/Y/Z, scale X/Y/Z, has its own variable selector.

How a binding behaves

• Unbound axis, keeps its static world-pose value.
• Bound axis, reads the variable's value every frame while simulating (degrees for rotation axes, scene units for position).

Bind only what moves. A cylinder that strokes along X binds position-X to Cylinder_Position and nothing else.

Layering with kinematic objects

Mechanism objects (paths, cranks, linkages, arms) compute their own motion from their kinematic inputs, you don't bind their solved pose. Bindings on a mechanism object move its base: a whole robot riding on a variable-driven gantry axis is exactly that, position-X bound on the manipulator object itself.

Example: a 3-axis gantry

1. Create variables Gantry_X, Gantry_Y, Gantry_Z (from cams in Simulation; from PLC axes in Online).
2. One object per moving stage, parented in a chain: bridge → carriage → z-slide.
3. Bind position-X on the bridge, position-Y on the carriage, position-Z on the slide.

Each stage carries the next through the hierarchy; three bindings animate the whole gantry.
