SurfaceType

Used to determine how a surface should be displayed on a part and how automatic surface joints should behave.

Note

Glue, Weld, Studs, Inlet and Universal surfaces only appear in-game when the part’s BasePart/Material is set to Plastic.

Name	Value	Description
Smooth	0	Makes the side appear without any surface detail (except for outlines). Does not create join by default
Glue	1	Makes the side appear with thick diagonal "X"s. Creates a weak join to other surfaces which will break if enough force is applied to one of the parts
Weld	2	Makes the side appear with thick diagonal "X"s. Creates a join to any surface except for Unjoinable.
Studs	3	Makes the side appear with square studs. Creates a join if moved next to a Inlet or Universal surface
Inlet	4	Makes the side appear with holes where studs would be. Creates a join if moved next to a Stud or Universal surface
Universal	5	Makes the side appear with both Studs and Inlets in a checker pattern. Creates a join if moved next to a Stud, Inlet, or another Universal surface
Hinge	6	Makes the side appear with a yellow hinge. Any part connected to this hinge will stick to the side and rotate using physics
Motor	7	Acts the same as a Hinge, but has a grey ring around it and automatically rotates any part connected to it
SteppingMotor	8	Functions identically to a motor. It may have functioned differently in the past, but that functionality no longer seems to exist
SmoothNoOutlines	10	Same as Smooth, but removes the outlines of the surface
