A number of default constraints facilitate manikin manipulation:

When you insert a manikin, two placement interfaces are automatically added to the manikin structure, one for the right forefoot, and one for the sacrum (hips). The placement interfaces appear in the Manikin Tree. To view the default constraints, right-click the manikin placeholder and choose Edit Definition from the shortcut menu.

When you place the manikin and select the posture, one of the placement interfaces is activated, the right forefoot interface if you select Standing, and the sacrum interface if you select Sitting. When you select the Place on reference, a placement constraint is created between the reference and the right forefoot of a standing manikin, or the sacrum of a sitting manikin.

A manikin's trunk is constrained so that it is always rigid, making manipulation easier. To move the spine, you must select a spine segment from the Manikin Tree and unlock the spine (clear the snapshot constraint). You can then add more specific constraints such as locking specific vertebrae to prevent rotation (the DOF3 constraint).

A manikin's hips and toes are locked. If you select a leg, the toes lock into place on the ground. You can then change the location of the foot by dragging the manikin's toes by themselves. Toe and hip constraints are temporarily turned off when they are dragged.

When you select another segment to drag, the default constraints on the first segment are turned back on. If you drag the hips up and down, the toes remain on the ground. To manipulate the manikin into a squatting position, drag the hips.
