you need to be a member of roblox :D
Use the Roblox Studio.
You can build places on Roblox by using the Roblox studio or by building in game. To access the Roblox Studio click your computer's start menu, then programs, then Roblox, and finally Roblox studio. Then click "file" > "New place" to build a Roblox place.
Go to profile in MY ROBLOX or Places and press the build button.
Builderman is a staff member on ROBLOX. Add me roblox name: TheFurryFox
Uninstall roblox, start, all programs, roblox, uninstall, then reinstall it after downloading it again. Or just redownload and reinstall roblox.
Go to Roblox wiki:)
To build a level on Roblox first click your computer's start menu>programs>Roblox studio. When opened select File>new place. You are now ready to build a place on Roblox. You can find helpful tutorials on how to actually build your place on the Roblox wiki.
Err...What?
Go to your profile, click Build. Oh, I forgot. You need a Roblox Studio to do that. Then you build.
Well, Man builds the stuff in Roblox, and Roblox is just the tool, therefore does not build. Since Roblox cannot build, we must assume that Man is the better builder.
you press the build button under the play button
