Answer:
When creating a Rhino Grasshopper algorithm, it is useful to create models which are ready to be calculated or designed.
For example, when defining structures with membranes or cables, a freshly created model without add-ons cannot be successfully calculated.
In order to create a new model with add-ons enabled, you need to consider the "Use template" option in the RFEM 6 Export Component in Grasshopper.
To enable it, you need to give it information about an absolute path to a RFEM 6 template file.
After connecting this data, the new model will be created with the use of this template and, for example, this allows you to automatically enable the Form-Finding add-on in the model.
Make sure the Overwrite Input from the Export Component is set to "False".
