Join Objects

Select line, arc, elliptical arc, open polyline, open spline or helix to join to source or [?]:

Select the source object to which other objects will be joined, or multiple objects to join without specifying the source object. Press ENTER.

Select lines to join to source or [?]:

Specify objects to join. Press ENTER.

Line (LINE)

Only line segments can be attached to the source line. The objects should be collinear, but there may be gaps between them. The resulting object for line segments lying on the same line will be a single line; for non-collinear segments – a polyline.

Polyline (PLINE)

Line segments, polylines, and arcs can be attached to the source polyline.

The objects should be coplanar. There should be no gaps between the objects. The resulting object will be a single polyline.

3D Polyline (3DPOLY)

Line segments, polylines, and arcs can be attached to the source 3D polyline. There should be no gaps between the objects. The resulting object for coplanar objects will be a polyline, for non-coplanar objects – a 3D polyline (joining a linear object) or a spline (joining an arc object).

Arc (ARC)

Only arcs can be joined to the source arc. The objects should have the same radius and center point (lie on the same imaginary circle). There may be gaps between the arcs. Arcs are joined in a counterclockwise direction from the original arc.

The Close option converts the source arc to a circle.

Elliptical Arc (ELLIPSE)

Only elliptical arcs can be joined to the source elliptical arc. Elliptical arcs should be coplanar and have the same major and minor axes. There may be gaps between the arcs.

The Close option converts the source elliptical arc to an ellipse.

Spline (SPLINE)

Any linear or arc object can be attached to the source spline. All objects should be adjacent, but may be non-coplanar. The resulting object is a single spline.

Helix (HELIX)

Any linear or arc object can be attached to the source spiral. All objects should be adjacent, but may be non-coplanar. The resulting object is a single spline.

Line

Created by joining collinear lines. Lines can have gaps between the endpoints.

Arc, circle, ellipse

Created from joining coplanar arcs (elliptical arcs) with the same center point and radius. Arcs can have gaps between the endpoints. Lengthening is made in the counterclockwise direction.

Options:

Convert arcs to circle? [Yes/No] <Yes>:

          Yes – a circle is created from arcs;

          No – one arc is created. If arcs form a full circle, the arcs are not joined.

Close ellipse? [Yes/No] <Yes>:

          Yes – an ellipse is created from elliptical arcs;

          No – one elliptical arc is created. If arcs form a full ellipse, the arcs are not joined.

Polyline

Created as a result of joining coplanar lines, arcs, polylines, 3D polylines.

When joining linear objects lying on the same straight line, a command line prompt appears:

Join into polyline with one segment <Yes> or [Yes/No]:

          Yes – one polyline with one segment is created;

          No – one polyline with several segments is created

3D Polyline

Created by combining coplanar non-coplanar linear objects (segments, arcs, polylines, 3D polylines).

Spline

Created as a result of combining non-coplanar objects or splines with other objects.

Select source object or multiple objects to join or [?]:

Specify the first arc. Press ENTER.

Select arcs to join to source or [?/Close] <Close>:

Specify the second arc. Press ENTER.
