JoinForm[type]
is a graphics directive that specifies what type of joins should be used to connect segments of lines, tubes, edges, and related primitives.
Details

- The following types can be used in JoinForm[type]:
-
"Bevel" truncate the corner "Miter" extend the corner toward a point {"Miter",d} extend by at most d times the line width "Round" cover the corner with a disk None equivalent to "Bevel" - JoinForm works in both 2D and 3D.
- In 2D, the default is JoinForm[{"Miter",3.25}]. In 3D, the default is JoinForm["Round"].
- JoinForm[{"Miter",1/Sin[θ/2]}] gives sharp corners for any join angle larger than θ.
- JoinForm can be used inside EdgeForm.
