Surface (Property)

Properties

This property is a summery of 6 different properties that perform the same action. They are BackSurface, BottomSurface, FrontSurface, LeftSurface, RightSurface, and TopSurface.

Surface
Property	Enum SurfaceType
Description	Sets what type of surface the side is.
Member of	[[RBX.lua.Flagstand, Part, Seat, SpawnLocation (Object)|Flagstand, Part, Seat, SpawnLocation]]

The SurfaceType Enum for the surface property has 9 numbers:
Enum	Name	Description
0	Smooth	Does not form a bond with any other surface, except Weld.
1	Glue	Forms a loose bond with other surfaces.
2	Weld	Forms a strong bond with other surfaces.
3	Studs	Only forms a weld-like bond with inlet surfaces.
4	Inlet	Only forms a weld-like bond with studded surfaces.
5	Universal	Forms weld-like bonds with Weld, Studs, Inlet and itself.
6	Hinge	Forms a hinge-like bond with other surfaces, with free movement.
7	Motor	Forms a hinge-like bond with other surfaces, without free movement. A motors behavior depends on the surface input.
8	SteppingMotor	Same as Motor.
9	Unjoinable	Will prevent ROBLOX's building tools and the studio's built-in tools, as well as some user-made tools, from creating joints between parts using this surface. Excluding this particularity, this surface type currently works like the Smooth SurfaceType.

The following table explains how SurfaceTypes work:

Surface Types

SurfaceType	Weld	Universal	Studs	Inlet	Glue	Smooth	Unjoinable
Weld	Weld	Weld	Weld	Weld	Weld	Weld	Weld
Universal	Weld	Snap	Snap	Snap	Glue	No Joint	No Joint
Studs	Weld	Snap	No Joint	Snap	Glue	No Joint	No Joint
Inlet	Weld	Snap	Snap	No Joint	Glue	No Joint	No Joint
Glue	Weld	Glue	Glue	Glue	Glue	Glue	Glue
Smooth	Weld	No Joint	No Joint	No Joint	Glue	No Joint	No Joint
Unjoinable	Weld	No Joint	No Joint	No Joint	Glue	No Joint	No Joint

Notes

• The Unjoinable SurfaceType currently acts like the Smooth SurfaceType, but it might in the future not form joints with any surface. This is currently being debated by the admins.
