Draw Animation is an interesting Python script that will allow you to move an object and record its animation in real time while it is in motion. If you have used After Effects before, Draw Animation is very similar to Ae’s Motion Sketch, recording and adding keyframes as you move an object with the mouse.
This tool creates an animation based on the pen/mouse
Guillaume FERRACHAT’s Draw Animation script reates an animation on the selected object in Maya based on your pen or mouse, creating a keyframe on every frame, which you can later simplify in the curve editor. Place the .py file in your Maya default scripts folder, run the script which will bring up a small panel with a record button, that, when pressed will start the process.
