As a manufacturer we will expect individual part files, not a multi-body part. This is for ease of manufacture and also for document, revision and manufacturing control. One file makes it impossible to do proper part number and revision control in a manufacturing environment.
Thank you for your response Anna.
We are still in the design phase. After these files are sent off to the engineer they will make modifications and so will we until, after a few iterations, the parts are ready for manufacturing.
Can the solid bodies be saved out as individual part files when we get to that stage?
