Perhaps not within the scope of the application, but one thing that would be enormously helpful for me would be a simple way to build a mechatronic assembly and then export th kinemetics equations for the system (even just the state space model parameters would be helpful).
Even better would be a way to place sensors and actuators, specify materials and detailed structure of components (or at least their shape and moments), and then export Mathematica / Matlab / C-code fragments for modeling (algebreically or numerically) the system and sensors.
The ideal (though probably practically impossible given the number of possible observers, controllers, and architectures) would be to automatically generate code for things like an LQR controller or feedforward model based controllers.
For example, the user could model a quadrocopter, placing a 9dof sensor (accelerometer / gyro / magnetometer), and four brushless DC motors with speed controllers and then Fusion 360 would figure out the equations governing the system's dynamics, the math for fusing the sensor data to make an IMU and the necessary control code all of which could be exported as C code so someone without significant background in control theory could quickly build and control a complex mechatronic device.
