How to label and measure in 3D

In the 3D view, pick a style (ball and stick, stick, space filling, ionic radii, wireframe) and turn on Hydrogens (H), Labels (T), Lone pairs (L), Orbitals (O), Bond angles (A) and Symmetry elements (S).

Open the 3D view (Shift+D).

Style

The first buttons on the upper bar set the style: Ball and stick, Stick, Space filling, Ionic radii (ions at Shannon's six-coordinate radii, other atoms at van der Waals radii) and Wireframe. Look and Material set how the camera and surfaces render.

What to show

Button Key Shows
Ground grid G A grid to orient the structure against
Hydrogens H The hydrogens, placed by VSEPR (they are implicit in the drawing)
Labels T Element symbols, and R/S and E/Z from the drawing
Lone pairs L Lone pairs on every atom that has one
Orbitals O The orbitals attached to atoms, see-through
Bond angles A The angles at the selected atom. Select an atom first
Symmetry elements S Rotation axes and mirror planes of this conformer

Views

It shows the Label, Charge, Isotope and Hydrogens, the Query atom settings for substructure searches, and Shape at this atom with the steric number, AXE class, geometry, hybridization and ideal angle.
