Nolimits help

I was wondering if anyone knows how to the rct import button in one of the menues in the editor just wAnt some help so if u know please tell me

.... Huh? Ummmm, if you mean how do you use it, go to file: import RCT track, then locate the file. Some of the files cannot be imported, I forgot why, but they can't.

I recommend never using that, especially if you're a beginning designer. The trackwork that RCT uses will give you the wrong impression of what is "good" as far as trackwork on real coasters is concerned.
BUT, if you must know, go to File -> Import RCT Track, and then find your RCT trackfile in your system. It should then show up.

^and BTW they have to be RCT1 tracks
