Always save your file using "File" and not "Document." Document will take a snapshot. Saving as "Tools" is cleaner but it deletes the history.

• Use a Sphere3D and click "Make Polymesh 3D" to activate it.
• Make sure you are in Edit mode (T).
• Turn on the floor (F) and symmetry (X).
• Set the material to MatCap Gray.
• Subdivide a couple of times just to get started.
• Sculpt out, then sculpt in to define planes. This is a trick that is also covered in Hard Surface in ZBrush video as well.
• Don't go into details too early.
• If you need to, go to a lower subdivision and re-DynaMesh.
• Underneath Geometry tools, turn on *Mirror and Weld (*test this as it mirrors and welds based on forward facing direction, even if your model is not forward facing). The other one to use is Deformation → Mirror. After using mirror (and verifying it works correctly), then turn on Mirror and Weld. This will take some playing to work.
• Radial Symmetry allows you to define the points of an array and will create symmetrical operations based on the number of points around the axis. This is under the Transformation menu, and is the (R) button.
• Symmetry is ALWAYS subtool based.

Subtools

Rename your subtools, otherwise it gets very messy. - Henning Sanden

• Append: Adds the select tool as a subtool.
