MX Simulator

Hello mx sim community, I need help with track editing. I need help with how to start over on a track. I made a crappy track and want to start from scratch. Do you guys know any videos or can tell me what to do. If you would rather dm me on instagram, my instagram is @mxfacts

Look at this playlist, much stuff in there that may be useful: Track editing: http://www.youtube.com/playlist?list=PLdn_lNXG_pqukvgwuE2EzrlXy7OLbmSrb
