Select Permute, Rotate & Mirror in the ProcessGeo section and click the Edit… button to change the input parameters.

After selecting the desired operation in the dialog, change the corresponding parameters and click OK. Then, click Permute.

Rotate 90° turns the structure by 90° around the given axis and in the given direction.

Mirror mirrors the whole structure in the selected direction.

Permute changes the allocation of the axis for the current structure.

All operations in Permute, Rotate, Mirror keep the analytic information of the structure (GAD data).

Observe the effect of the following permutations on the position of a structure depicting the casing of a filter. First, the structure is simply rotated counter-clockwise by 90° around the Y-axis. Then, it is mirrored in the Z-direction.

The permutations , , and flip or switch the axes. The shape of the domain changes accordingly. In the example below, the side opening of the filter casing that initially opens towards the X-axis, changes to the Z-axis after the permutation.

If the same permutation is applied two times, the original state is achieved again.

Observe that the flipping of the axes is the same as first rotating and then mirroring the structure as it is shown above.
