Quick Start

Once the component is selected, use the Move command's manipulators to
translate or rotate a component. Note that if other components have
constraints to the component being moved, they will also move to satisfy the
constraints.
If you want to position a component relative to other components, you can
use the Assemble command. The Assemble command can be used with or
without constraints. In this case, we don't want to create constraints, but
Assemble allows us to easily snap together component geometries, even
without constraints. Assemble is a highly interactive command, that allows
dynamic dragging of the selected component, and infers other geometries to
snap to, as the component is dragged. You can also to perform this same
snapping in a more directed way, by explicitly picking the geometries to snap.
The following video shows both styles of interaction;
