This was my very first experience using LDD. I used my flag as a base for the circuit boards and used a lot of 1x1 tiles to maximize piece count (although there are other tiles which means everything would hold together if it were built with actual bricks)
I figured out after using the 1x1s that actually I could add make those bits grey in places to look like components, I think it has a cool aesthetic.
I would lastly like to say that although I enjoyed using LDD and could see it being useful for larger projects but I found that part of the fun of using real bricks is that it is easier to find new techniques. Hence although I can completely understand why people use LDD, I probably wont be using it in the future.
