There are some solutions:
- Plans can printed to full paper size (Plan-Print-Plan). If you select a PDF printer (e.g. "Microsoft Print to PDF") you can print this file to other scales.
- You could export plans as DXF (Caves-Export-DXF) and proceed it with other tools.
- Drawings you could export as PDF (Drawings-Drawind-Vector Graphic) and print it to other scales.
