Join Objects

Ribbon: Home, Draw - Modify > Join

Menu: Modify – Join objects

Toolbar: Modify –

Command line**: JOIN**

The Join objects command joins separate segments of objects into one object by combining their endpoints.

The command can be applied to segments, open polylines, 3D polhylines, arcs and elliptical arcs, open splines and helixes. Auxiliary lines, rays and closed objects cannot be connected.

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.

Command prompts:

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.

Source object

When specifying one source object, a prompt is displayed in the command line:

There are the following features for each type of source object:

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

(PLINE) 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.

Multiple objects to join

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

For example, 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 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 – 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 – 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 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.

Example: Joining arcs by selecting a source object:

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

Specify the first arc. Press

ENTER.

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

:

Specify the second arc. Press ENTER.

Arrays

This command is used to create two-dimensional arrays of the selected objects by placing their copies on the specified circle, in the nodes of the specified rectangular grid or along the trajectory.

Each array object is called an array element and can consist of multiple objects. The source object of an array can be a block.

Arrays can be associative and non-associative (2D arrays, 3D arrays).

Associative Arrays

Associativity allows you to quickly make changes in the entire array due to the established relationship between the elements, while all the elements of the associative array are perceived as a single object. In

an associative array, you can change the number of elements and the distance between them, set the number of levels. You can control the parameters of an associative array using the array grips or Properties bar.

An associative array can be divided into separate objects by Explode command.

The Associative option of the commands for creating and editing arrays allows you to specify whether the arrays will be associative or non-associative. Associative array elements are selected, edited, and behave like a single dynamic block. Non-associative arrays, after the end of the command, decay into independent objects.

Rectangular Array

Arranged distribution of copies of objects in any combination of rows, columns, and levels.

Creating an array:

• 1. Run the command.
• 2. Select objects to create an array, press ENTER. From this moment, a preview of the array based on the current values of its parameters will be displayed on the screen.
• 3. In the Properties bar, in the command line, context menu or using a dynamic input, specify the array parameters.

Command prompts:

Select objects or [?]: Selecting objects to be used in an array. The prompt appears if the objects were not preselected before the command starts.

Press ENTER upon the selection is completed.

Command options:

The command options can be edited in the Properties bar, in the dynamic input menu or in the command line.

Note

When specifying values in the dynamic input menu or command line, you should return to the Properties bar to display the actual values on it.

Associative Determines whether array objects are associative or independent.

Base point Determines the location of the array’s base point.

Count Specifies the number of columns and rows in the array.

The option initiates the following prompt in the command line:

Enter the number of columns: Enter the number of rows:

Identical to options Columns and Rows in the Properties bar.

Spacing Specifies the spacing between rows and columns measured from identical points in array objects (for example, the spacing from the top of one object to the top of the second object).

The option initiates the following prompt in the command line:

Specify the distance between columns [Unit cell]: Specify the distance between rows:

This button switches on the mode for cutting of lines before their intersection.

This button switches on the mode without lines cutting.

This button switches on the additional dimensioning mode.

The button becomes available when the Measure fillet button is enabled.

This button switches the automatic dimensioning mode on/off.

This button temporarily closes the dialog box to allow copying of properties from other fillet. The command does not work on fillets created with the participation of a polyline, since when setting up a fillet, all the components are collected into one polyline.

Show at start

A box that, when unchecked, stops displaying the dialog box for all subsequent command calls, i.e. allows you to reconfigure the command to work in non-dialog mode. To open the dialog box again, select the Properties option in the command line or context menu. This mode of operation is convenient when you often need to use the command without changing its parameters.

Abort command by Esc

When the box is checked, pressing ESC interrupts the command. When the box is unchecked, pressing ESC displays the Fillet dialog box.

Double-click or right-click in the fields to enter values will open the context menu with the list of the recently entered values:

Options in the context menu and in the command line are available during the process of fillet creation:

Command options:

Properties The Fillet dialog box opens to change the chamfer parameters.

neW Finishes the creation of one group of fillets and starts another. The command is applied when you need to create some fillets with one radius

on one object and with the same radius on another object:

Chamfer Switches to the mode for creating chamfers. The Chamfer dialog box opens

to specify the parameters of the fillet.

polyLine Constructs fillets for all polyline vertices that are intersection points of two

straight-line segments. The operation ignores clipping and dimensioning

modes.

To create a fillet:

• 1. Select the first object.
• 2. Move the cursor over the second object. Fillet options will be presented.
• 3. If there are no fillet options, select the Properties option from the context menu or the command line and adjust the radius.
• 4. Select the second object.
• 5. Select the fillet from the presented options.

Features of the command work

The command works in 3D. To perform the command, the source entities should be located in the same plane.

If you press and hold SHIFT when selecting the second object, then a corner will be formed (closing in the intersection point and cutting off).

For pairs of objects LINE-ARC, ARC-LINE and ARC-ARC, two types of fillet are available: outside and inside ones.

Outside Inside

A fillet that combines inside and outside tangency is additionally available for ARC-ARC pair.

Note

Availability of different types of fillet depends on the fillet radius. Outside and combined fillets require larger radiuses than for inside fillets.

Selecting two parallel lines will create a fillet with a radius equal to half the distance between them (regardless of the specified Length). The sides will automatically align to the longest line.

Fillet of parallel lines also works for segments of the same polyline.

A fillet side depends on the mouse cursor position when the second object is selected

When making an insertion of a fillet between neighboring polyline segments, a polyline retains its integrity.

If when using the command, a fillet is created for two polylines, then as a result it will be a single polyline object.

If segments of one polyline separated by other segments are selected, then all these intermediate segments are deleted.

When making a fillet while specifying a second object, a point will be taken at the location of the object and a fillet will be constructed based on this point. Examples of fillets with the same parameters but different specified points:

Fillet Command (Non-dialog Mode)

Command line: F, FILLET

Creates a fillet using the command line.

Command options:

? Opens additional options for selecting objects.

Undo Cancels a previous action in the command.

POlyline Creates fillets for all polyline vertices which are the intersection points of two

straight line segments. When the Trim option is enabled, fillet lines become new

segments of polylines.

RaDius Sets the fillet radius. When set to zero, objects are lengthened or cut to intersect.

Trim Controls objects cut to fillet lines.

Trim -selected objects are removed to the endpoints of the fillet lines. If the objects do not intersect with the fillet line, they are lengthened or clipped to the

endpoints of the fillet line.

No_Trim – selected objects are not cut.

Multiple Adds a fillet to multiple sets of objects.

Command prompts:

Soecify first object or [?/Undo/POlyline/RaDius/Trim/Multiple ]:

Specify second object or Shift-select to apply corner or [?/RaDius]:

Select the first fillet object or the required option to set parameters.

Select the second fillet object or use SHIFT key to form an angle in the intersection

point. To change parameters, select the required option.

Explode

The Explode command divides complex objects, such as polylines, dimensions, hatches and blocks into separate elements. For example, dividing a polyline causes its separation into lines and arcs; an associative dimension divides into a set of simple objects; a block is divided into a set containing its objects; multiline text is divided into lines.

The Explode command is applied only to one nesting level of a complex object, i.e. if it is required to explode a polyline belonging to a block, firstly you have to explode the block and after that the polyline.

Command options:

? Opens the additional options to select objects.

Command prompts:

                     Select the next object and press ENTER to finish the command.

Explode Geometry

The Explode geometry command, as compared to the Explode command, splits complex objects into entities along the entire depth of the nesting levels. For example, it will explode several nesting blocks at once into their constituent segments, arcs, polylines without the need to repeatedly call the command.

Command options:

? Opens additional options for selecting objects.

Settings Changes the explode settings.

The option opens the following prompt in the command line:

Settings [Autoselect/Source/Properties/Text/Exit] :
