With Paint 3D, you can easily transform a freehand sketch into a three-dimensional object.
First, select the 3D objects icon from the top menu. Then on the right menu, scroll down to the 3D doodle tray.
Note: The Sharp edge tool will give your doodle depth, like a cookie cutter, while the Soft edge tool will inflate your sketch into a puffy 3D object.
Create an object by selecting the type of 3D doodle you want. Then, draw a shape in the workspace with your mouse, pen, or touch. Connect the dots to make your doodle 3D!
