Hi,
the best way is probably to use the tools available in EWM, means you create structures and defines the bins from there.
An upload is also available, but yes, for this you need to fill a CSV file with all the required data, and especially the coordinates are not simple to calculate, because this is not a straight function.
Can AutoCAD export into a CSV file? Or Excel read AutoCAD files? Don't know, so you have to figure this out. But then for sure AutoCAD does not include the other data you need, like bin types, so you need to fill this as well.
"We are currently searching for the easiest way to populate X, Y, Z bin coordinates, angles and all other data with extreme accuracy in EWM."
Why with "extreme accuracy"? Yes, it should be correct. But you should have learned by now that you describe a corner of a bin, so you should not exagerate...
