It seems like your only hope is that they can export it by layers in Microstation, sending you different subassemblies. Then you can group them into the final assembly in SW.
Thank you for your reply
That's what I do today. But it's a lot of work when you have to split it up in hundreds of layers, giving you hundreds of step files to import.
Is there any way of importing several step files and put them in an assembly at once?
