hi, new to this, having a few problems sorting rct2 out, how do you biuld bridges and raised platforms? john.

Start on the ground and build your way up. You can't start in the air.

It's all kind of confusing, but I think there might be some type of tutorial in there about how to do that stuff. If not, then you'll have to do a little expirementation to get used to it. Besides that, welcome to rctgo!
