A set of tools for blender 3.0+ that will accelerate and enhance your modelling process. In a matter of seconds, upscale the resolution of your geometry (even boolean cutouts!) without distorting the faces around, undo/redo your bevels and much more! I am looking forward to hearing your feedback and feature suggestions. Have fun and I hope you enjoy using the tools!
