MouseOK    Ribbon: Home, Draw - Modify >  Join

MouseOK   Menu: Modify –  Join objects

MouseOK   Toolbar: Modify –

KeyboardOK Command line: JOIN

The Join objects command joins separate segments of objects into one object. The command can be applied to segments, arcs and open polylines. The command can be applied to segments, arcs, open polylines, elliptical arcs, open splines and helixes. The resulting object type depends on types of selected objects, type of object selected as the source one, as well as coplanarity of objects.

Pre-selection of objects is allowed.

note.        Construction lines, rays and closed objects cannot be connected.

Command prompts:

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

To select lines, polylines, arcs, elliptical arcs, helixes or splines.

 

After selecting a source object, press ENTER.

Specify objects to join.

Further command prompts depend on the choice of the source object or several objects at once to join.

Source object

Specifies one source object to which other objects will join.

Additional restrictions for joined objects types:

Line segments

Must lie on the same line.

There can be gaps between segments.

Polylines

Lines, polylines and arcs can be joined to a polyline.

Objects must lie in one plane. Parallel to the XY plane of the UCS.

There must be gaps between objects.

Arcs

Objects must lie in one imaginary circle.

There can be gaps between arcs.

Elliptic arcs

Objects must lie in one imaginary ellipse.

There can be gaps between arcs.

Helix

Any linear or arc object can be joined to the source helix. All objects must be contiguous, but can be non-coplanar.

The resulting object is one spline.

Spline

Any linear or arc object can be joined to the source spline. All objects must be contiguous, but can be non-coplanar.

The resulting object is one spline.

Command options:

?

Opens the additional options to select objects.

Close it

Transforms an arc to a circle.

 

Selection of first arc

Selection of second arc

Result

Command prompts:

Select source object or [?]:

Specify the first arc.

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

Specify the second arc.

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

Press ENTER to finish the command.

Multiple objects to join

Joins multiple objects without specifying the source object.

When selecting multiple objects of different type to join, the resulting object will be the one with the most complex type.

So, when you apply the command to the selected lines and polylines, the result will be a single polyline. If the selection includes a polyline, line and spline, the resulting object will be a spline.

The creation rules and types of resulting objects are the following:

Line object

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

Arc or circular object

Created from joining coplanar arcs with the same center point and radius. Arcs can have gaps between the endpoints. Lengthening is made in the counterclockwise direction. A circular object is created if joined arcs form a complete circle.

Spline

Created as a result of joining splines, elliptical arcs or helixes together or to other objects. The objects can be noncoplanar.

Polyline

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