I really wanted to add space shuttle and ISS parts into the tech tree so I started looking at Benjee10's Shuttle Orbiter Construction Kit, Benjee10's Habtech2 and Beale Tantares parts required to build the ISS. I've been puzzling where to put parts. The shuttle parts were easy as I just matched the given piece to the stock piece of the Mk3. For Habtech2, the modules were fairly easy. For the most part I put crew compartments into the spaceExploration and anything with science into Advanced Exploration with the Cupola module going into simple command pods. I wasn't sure where to put the trusses as I couldn't find anything like it on the tech tree. The solar panels have their own issue as they produce so much more energy then anything I saw. I temporarily assigned them to advanced solar. As for the Russian pieces, I placed them in nodes that appeared to me to have simiar parts, but I still have blanks. You can find the spreadsheet I'm working on here
Any thoughts on where to fill in the blanks would appreciated and thoughts on I how I filled it out would be appreciated
