Proportional Modeling and Symmetry
Proportional modeling (Prop) and symmetry mode (Sym) now work better together, in particular when the proportional radius crosses the plane of symmetry. For proportional modeling, the new MoveProportional operator gets applied instead of a MoveComponent with a Proportional property. In symmetry mode, a single operator is applied instead of separate operators for each side.
For more information about proportional modeling and symmetry mode in general, see Using Proportional Modeling and Manipulating Components Symmetrically.
