Sorry if I disturb You but I don't get'it:
1. Why You prefer to use an older version?
I use the installer version and it's fully functional.
2. Why don't use Furniture Library Editor tool from Plug-in and tools to make sh3f?
I have also some Basic shapes category but in only one convenient position while I could rotate later.
For example the cylinder are horizontal while it keep the horizontal length even if I rotate it in other axes.
So when I export to csv I have the total length of pipe or wires with out other modifications.

P.S. I'm older than You and I also use debian. Is the main motive I boring You.
