Is there a way to send Arduino sensor data to a 3d model I've created
Sure. There are many 3D engines in various languages that easily support serial communication (to get the input from the arduino).
to a 3d model I've created in say, cinema4d?
I don't know the application, but my geuss is that this will not be possible unless you spoof the arduino as a mouse or joystick as mowcius mentioned.
Though you'll have to dig around whether its possible to create a plugin for it.. even then its the question whether it'll be possible to do in the plugin.
Your best bet is probably to spoof a mouse to do this.
