The following rules apply when you join different types of objects using a
single selection set:
■ A line object results from joining collinear lines even if there is a gap
between their endpoints.
■ An arc or circle object results from joining coplanar arcs with the same
center point and radius even if there is a gap between their endpoints. A
circle object results if the joined arcs form a complete circle.
■ A spline object results from joining splines, elliptical arcs, or helixes
together, or to other objects.
■ A polyline object results from joining lines, arcs, polylines, or 3D polylines
that are coplanar.
■ A 3D polyline results from joining non-coplanar, non-spline objects.
NOTE When joining coplanar arcs with the same center point and radius,
lengthening occurs in a counterclockwise direction.
List of Prompts
The following prompts are displayed.
Select source object: Select a line, polyline, 3D polyline, arc, elliptical arc, helix, or
spline.
After selecting the source object, the prompt that follows depends on the type
of source object selected.
Line The line objects must be collinear (lying on the same infinite line), but
can have gaps between them.
Polyline The objects can be lines, polylines, or arcs. The objects cannot have
gaps between them, and must lie on the same plane parallel to the UCS XY
plane.
