When we receive 3D geometries to create a 3D Machine the machine is often (always for millturn) not well positioned in the 3DEXPERIENCE (as you can see on the picture).
On my side I used this method to position the machine on the floor before to create the resources.
There is perhaps more simple (share), but this method is not so long and you have to do only ontime when you create the resource
For me it is better to have the machine on the floor when I open an Manufacturing cell, it is an important 'nice to have' !
