Windchill Workgroup Manager supports the Large Assembly Mode feature of SOLIDWORKS. Large Assembly Mode also stated as lightweight format does not fully load all components to improve performance. This feature is set from Tools > Options > Assemblies > Opening large assemblies.

When a SOLIDWORKS assembly containing child components more than the set limit, is opened in SOLIDWORKS through Windchill Workgroup Manager, the assembly is opened in Large Assembly Mode. On the contrary, when a SOLIDWORKS assembly is opened from a local drive outside the workspace, it opens in full mode loading all components and references, even though the Large Assembly Mode was enabled. This is to ensure that all references can be found before checking in to Windchill.

To view the assembly outside the workspace in Large Assembly Mode, first open the assembly in SOLIDWORKS and then perform File > Save to Workspace. This adds the assembly and all its dependents into the workspace. Once the assembly has been initially saved to workspace, subsequent opening of the assembly from the workspace in SOLIDWORKS adheres to ‘Large Assembly Mode’ rules.
