blender 2.8 drawing over 3d object

Blender has a pen function called Grease Pencil.
In addition to writing notes and creating 2nd animations, information technology is also possible to convert lines drawn with Grease Pencil into 3D models.

In this commodity, I will show you lot how to convert lines fatigued with the grease pencil into a 3D model and how to create a decorative mask.
