Création d'une pièce à plusieurs corps à partir d'un assemblage

With the introduction of SOLIDWORKS 2024, we can now convert an entire assembly into a separate multibody part file that stays linked to the parent assembly. This was not possible in the previous versions of SOLIDWORKS.

In previous versions, we could save an assembly as a part but there was no link maintained between the files meaning that changes to the assembly would not propagate to the part file. The user would have to repeat the Save As process to create an entirely new part each time a change was made. In SOLIDWORKS 2024, the part maintains its link back to the assembly so that any changes to the assembly automatically propagate down to the part. However, the features created in the part are not reflected in the parent assembly. Any post-assembly operations, such as material removal, can be performed on the part and they will appear in downstream applications.

Note: Features added to the part do not propagate to the assembly!

How to Make a Multibody Part from Assembly

Make Multibody Part Property Manager

To create a multibody part from an assembly do the following in the assembly:

1. Click Tools>Make Multibody Part.
2. Select the part template to use if prompted. This will bring up the Make Multibody Part Property Manager.
3. Select the assembly configuration to create the part from.
4. Select the entities to transfer.
5. Select other options as needed and click OK.

Entities Available to Transfer

• Solid bodies – Included by default
• Surface bodies
• Axes
• Avions
• Coordinate systems
• Material – Body-level material takes precedence over part-level material

Other Options in the Make Multibody Part command

• Break link to original assembly – If this is selected, the resulting part file will not be linked back to the original assembly meaning that changes to the assembly will not propagate down to the part.
• Propagate from original assembly – Propagates color assignments from the components of the original assembly to the part. This includes colors assigned to the parts, bodies, features, and faces.
