My suggestion should actually help as the geometry is detach from the LoadGroup.

However, as the load that you will apply to your model are linked to load cases, and the load cases are linked to the load group, you need to use the load cases from the `template file`.

I’m thinking if it would be possible to create these custom load case realationships by just adding them into the struxml-file via a python-component i GH? That would be beautiful 🥹

The custom relationship can be created in the `template` file.

I have solved temporarily an issue related to the `LoadGroupDefinition` in the following .dll

Have a look at the attached example. It should be self-explanatory for you 🙂
