Copy ‘n’ paste will work but ya gota remeber to colour them before you use them. If it don’t then what I do is if ya want red. Click on the tip of triangle at red end. Then chose your colour look to see what letter your colour is under and do the same to the next. Tip of triangle then chose colour under same letter. I know it’s not fantastic but it does work.
I like using the Copy ‘n’ paste idea the best if you don’t have everything built you can keep a copy of the object off to the side and keep going back to it that saves you a lot time trying to match the colors
You learn sumat new every day I did not know ya could change colours on the walls like that. I thought that they would only go light brown colours. Sorry Biggs but I is gona have to use red brick walls to on my new track to they look cool.
