|
|
This script copies the axis orientation -- X, Y and Z rotations -- of the
|
|
active object to all selected meshes.
|
|
|
|
It's useful to align the orientations of all meshes of a structure, a human
|
|
skeleton, for example.
|
|
|
|
Usage:
|
|
|
|
Select all mesh objects that need to have their orientations changed
|
|
(reminder: keep SHIFT pressed after the first, to add each new one to the
|
|
selection), then select the object whose orientation will be copied from and
|
|
finally run this script to update the angles.
|
|
|
|
Notes:<br>
|
|
This script changes mesh data: the vertices are transformed.<br>
|
|
Before copying the orientation to each object, the script stores its
|
|
transformation matrix. Then the angles are copied and after that the object's
|
|
vertices are transformed "back" so that they still have the same positions as
|
|
before. In other words, the rotations are updated, but you won't notice that
|
|
just from looking at the objects.<br>
|
|
Checking their X, Y and Z rotation values with "Transform Properties" in
|
|
the 3D View's Object menu shows the angles are now the same of the active
|
|
object. Or simply look at the transform manipulator handles in local transform
|
|
orientation.
