Are there any jobs that are similar to architecture but require less social skills?

With your skill set, 3-D modeling and animation may be a career path to explore. I know several people who work in this field. You must be very driven, be able to learn on your own and have a lot of patience to succeed in this field. One person I know creates 3-D images of underwater machinery. This allows mechanics and engineers make sure everything is 'just right' before they go down there. Another person with the same degree creates flight simulations for the military. Another person is working with a college to create educational video games. Many people go into this area wanting to create video games or Pixar movies, but there are many other uses for 3-D animation.

Architects have all sorts of personalities and social skills so please don’t count yourself out yet. But I will say that in most design profession you have to present your drawings/designs and/ideas to a client (or teacher or coworker) to collaborate or convince them that what you did is a good solution for their situation. But “Designing things “ as you say sounds more like industrial design or some sort of engineering (mechanical maybe) where you do more assembly of parts into a whole object. Architecture creates spaces that people live inside of- engineers develop objects that people use. Good luck and keep exploring and asking questions

Congratulations on being interested in finding the right career to follow.. It takes a special person to enter into a specific career field and meet the demands which that career area presents. The first step is to get to know yourself to see if you share the personality traits which make one successful in that area. The next step is doing networking to meet and talk to and possibly shadow people doing what you might think that you want to do to see if this is something that you really want to do, as a career area could look much different on the inside than it looks from the outside.  When I was doing college recruiting, I encountered too many students, who skipped these important steps, and ended up in a career/job for which they were ill suited.
