I'm a new KSP Player from Israel.
This probably a dumb question, but I wasn't able to figure it out or find an answer online.
On this Duna base video (https://www.youtube.com/watch?v=svE9Bkdo1AM&t=1s) by Matt Lowne.
How did he connect the Mk1 Crew Cabin on both sides?
Example : I'm trying to connect two upright PPD-10 Hitchhiker with a horizontal Mk1 Crew Cabin.
Hope to get an answer.
Tnx.
