3D Interoperability

I think WCS class is always right handed.

But Catia4 (and probably Catia5) supports both right and left handed coordinate system.

When importing a left handed coordinate system using Interop, how can I detect this CS is left handed, not right handed ?

I received this answer from Spatial support:

Hello,

Yes, we agree with you that we do not differentiate WCS as left-handed or right-handed. If you are interested in doing so, you can use following logic.

If vector product of x-axis and y-axis of wcs is same as z-axis of wcs, then the wcs is right handed else it is left handed.

Let's know if that works for you.

Thanks
