Addons give Blender additional capabilities and useful tools that will make you more productive. Here are some addons that I have enabled in Blender:
- ‘Add Mesh: Extra Objects’ – adds additional mesh objects that you can create in the 3D view (‘Shift-A’/’Mesh’/’Extra Objects’)
- ‘Mesh: 3D Print Toolbox’ – options appear in the tools panel to determine the volume of your model and also to check various constraints useful for 3D printing.
- ‘Mesh: Looptools’ – options appear in the edit mode tools panel that provide useful operations on loops of vertices like making circular shapes.
