You can translate or scale geometry in Patran by using the Transform action’s Translate method or Scale method. For information and examples on using either form, see
Translating Points, Curves, Surfaces, Solids, Planes and Vectors or
Scaling Points, Curves, Surfaces, Solids and Vectors.
On either form, you can choose either the Cartesian in Refer. CF toggle or the Curvilinear in Refer. CF toggle.
If Curvilinear in Refer. CF is chosen, you can specify either an existing cylindrical or spherical coordinate frame as the reference, and the translation vector or the scale factors will be interpreted as R,
, Z for the cylindrical system, and as R,
,
for the spherical system. (Both the
axis and
axis are measured in degrees.)
Figure 3‑7 through
Figure 3‑10 are examples of using the Translate and Scale methods with the Curvilinear in Refer. CF toggle.

Points along the z-axis of a cylindrical coordinate system and at the origin of a spherical coordinate system cannot be transformed uniquely in the
(cylindrical) or
and
(spherical) coordinates respectively. This is due to the fact that there is no unique
for points on the z-axis of a cylindrical coordinate system or
and
coordinates at the origin of a spherical coordinate system. Therefore, in Patran, any point on the z-axis of a cylindrical coordinate system or at the origin of a spherical coordinate system is not transformed.
