Scripting
FreeCAD Scripting Basics.

See the Python scripting tutorial.

A placement is internally defined by a matrix; in many cases it is simpler to represent it by means of two components, a point (vector), and a  value. The itself has different representations; it can be entirely defined by the value of a "quaternion", but it can also be described by a rotation  (unit vector) and a rotation  (radians).

Move the base point of the object, then rotate the object 45 degrees around the X axis.

The math module supplies a method to easily convert degrees to radians and has to be imported at first.
