In FreeCAD, Placement defines an object's position and rotation. The Placement concept is explained in detail here: Placement.
Example of setting a document object's Placement:
myObj = FreeCAD.ActiveDocument.ActiveObject pl = FreeCAD.Placement() pl.move(FreeCAD.Vector(2,0,0)) myObj.Placement = pl
Placement ( ) or (Placement) or (Matrix) or (Base, Rotation) or (Base,Rotation,Center) or (Base,Axis,Angle )Description: Constructs a placement, empty or with the given arguments, or as a copy of the given placement.
BaseReturns: a vector representing the Placement's position.
RotationReturns: a quaternion representing the Placement's rotation.
inverse ( )Description: computes the inverse placement
Returns: a placement.
move ( Vector )Description: moves the Placement along the given vector
Returns: nothing
multVec ( Vector )Description: applies the Placement to the given vector
Returns: the resulting vector.
multiply ( Placement )Description: multiplies this placement with another one
Returns: the resulting placement.
toMatrix ( )Description:
Returns: a matrix representing the Placement's transformation.
