using Data Export Wizard to write input echo (CII 4.50) the element and support directions are still mixed up when z axis is vertical defined.

Is there a fix available?

Seems that with flag z up CII rotate the results only and not the model itself.

However restraint output shows different (but right) directions compared to input echo "restraint data".

Modelled z restraints listed as y restraints, elements defined in z direction
are listed with y lenght ...!

There are no fixes available for Version 4.50. We just finished shipping last Friday.

Someone else also reported that the "Z-up" flag isn't working for the input export to ODBC. We will look into this.

You are correct with regards to the model not actually being changed by the "Z-up" flag. All we do is pass the data through a filter that displays the values for "Y-up" or "Z-up", wherever necessary.
