Geometric transformations available with move operation are:
Displacement: parallel displacement is applied to
selected objects for specified displacement vector. Parameters needed are displacement
vector components.
Rotation: selected objects are rotated around the
specified point for the specified angle. Parameters needed are center of rotation
coordinates and angle measured in radians.
Scaling: selected objects are dilated (constricted) by means of
homothetic transformation. Parameters needed are center of homothety and scaling factor.
The following table clarifies the parameters meaning with various transformation types:
