Answer:
For structures that occur relatively frequently, you can use the menu bar "Tools" → "Generate Model - Members (Surfaces)" to open different generators. If you cannot find the template you need, take a look at Block Manager. This can be opened via the menu "File" → "Block Manager" and is structured similarly to the Project Manager. Under the corresponding list items, you can find numerous parameterized structures, such as for silos or masts. Also, you can parameterize structures that you have modeled and then save them as a block.
