To hide weld constraints in Roblox Studio, go to the Model tab and turn off Show Welds or Show Constraints in the Constraints section. You can also use the shortcut Alt + W to toggle weld visibility.

What you’re seeing

Those orange/green lines are usually just Studio’s visual guides, not something players see in-game. They’re meant to help you edit parts and constraints while building.

If it still shows

  • Make sure Show Welds is off.
  • Make sure Show Constraints is off too.
  • If the lines keep appearing, check whether a plugin or Studio setting is forcing them on.

In-game behavior

Weld constraints are normally invisible during play, so this is usually only a Studio display issue. If you want, I can also give you the exact button location in the current Roblox Studio layout.
