frame multibody

We are currently considering how best to design a frame using Creo Multibody, and we would like to ask for your advice on the most appropriate workflow.

From a design perspective, the frame can essentially be considered as one box-shaped structure. Therefore, we would prefer to design the entire frame as a Multibody Part rather than creating and managing multiple individual Parts from the beginning.

However, from a manufacturing perspective, the actual frame is divided into four sections: the top, bottom, left side, and right side. Each section is manufactured and welded separately, and these four sections are eventually assembled to form the completed box-shaped frame.

This creates a difference between the way we would like to design the frame and the way it is actually manufactured.

At the moment, we are not sure which approach would be the most appropriate in Creo:

• Keep the frame as a single Multibody Part throughout the design process and somehow use the individual bodies for manufacturing and documentation, or

• Use the Multibody Part as the initial design model, and later create individual Parts from the bodies and assemble them according to the actual manufacturing structure.

We understand that both approaches may be possible, but we are unsure which would be considered the better practice, particularly when considering drawings, assemblies, BOM structure, and design changes.

Our ideal workflow would be to keep the design process as simple as possible for the designer, while still being able to represent the actual manufacturing structure correctly when the frame is produced.

Could you advise us on how you would recommend approaching this type of design in Creo?

We would also appreciate any suggestions for a workflow that balances the advantages of Multibody modeling with the need to eventually represent the four separately manufactured and welded sections.
