JOIN
Makes elements that meet end to end into one spline.
Syntax
JOIN @a,@b
JOIN @a,@b,@c,…
| Argument | Meaning |
|---|---|
| @a, @b … | The elements, in any order. Each must meet another where an end of one is the same point as an end of the other. |
Examples
LINE @1,P0,P1
LINE @2,P2,P1
P4=[250,500]
ARC3 @3,P2,P4,P3
JOIN @1,@2,@3

The spline runs P0, P1, P2, then round the arc to P3: @2 is turned round to run on from @1.
Notes
The first element keeps its direction; each of the others is turned round if it needs to be. Every element becomes a segment of the spline as it is, on the same points: nothing is converted. The elements are removed, or kept on the Construction layer if something else is defined on them.
Lines, arcs, Béziers, NURBS curves, splines and open polylines can be joined; circles, ellipses, closed shapes and elliptical arcs can't.
