[Paraview] [EXTERNAL] different orientation of input files

[David E DeMarle]

It shouldn't do that, certainly not randomly.

All the filter does is apply the transformation matrix you give it
(specified by the properties panel and/or by moving the box widget in
the 3D view) to the point coordinates and the vector and normal data
fields of the input data set to make a new data set.

Can you send a picture to the list to help diagnose what is going on?

Also, take a look at both the Rotate and Scale entries in the
Properties tab of the transform filter, and the Bounds field in the
information tab for both the input and output to the transform filter,
to make sure that you haven't unintentionally added any rotation or
scaling components to the transformation matrix.
