Ball Pen is my experimental tool in blender. 

You may think it as a "super snake hook". (some people say Z-sphere)

Sometimes I want to create meshes in 3D space by free hand drawing, for fast concept and solid, and no worry about topology.

- Fast

- Good for making monster, or backgrounds

- Remesh it

- Easier than sculpting


- In edit mode, right-click context menu to find the tool "Ball Pen". You don't have to select anything.

- Left mouse button to draw, you have to draw on top of something to start, then you can extend your line to anywhere. The depth is determined by view-plane

- Ctrl + Mouse wheel scroll to adjust ball size

- Ctrl + Left mouse button to draw with surface snapping. 

- Ctrl + Z to undo

- Q key to confirm the draw

- A key to switch to "rectangle" mode, it will create long box instead of sphere

- G key : move the last stroke

- R key : rotate the last stroke

- Right Click : Select objects (after select, you can press G to move and R to rotate)

If you want to use it in sculpting mode, you can tab to Edit mode when you sculpt, then use this tool, press Q to confirm. After using this tool, you can voxel remesh the mesh (blender's new sculpt remesh is powerful.)

Thank you for your interest.  :)
