Blender 2.8 extra meshes and primitives to start your project, the best included free add-ons

This overview is for people not familiar with Blender at all or if you want to dig a bit more and do something new with this great piece of free software.

A very rich choice of primitives to start your modelling, some of them are ready from the first time you start Blender, some others need to be enabled as free add-on in the preferences screen.
I tried to show some of the most useful shapes, curves, and meshes you can create with few clicks!

Special mention to the Rock Generator... it rocks! Literally, a super addition to the environmental creation tools!
