Join – Bricsys Support and Help Center

Joins lines, lightweight and old-style 2D polylines, 3D polylines, arcs, elliptical arcs, polyarcs, splines, and helices at their common endpoints.

The entity that results from the join depends on the input entities; see Rules, below.

Accessing the Command

: Join

Prompts you in the command bar:

Select source entity or multiple entities to join at once: (Select one or more entities, or enter all to select all entities in the drawing)

Select entities to join: (Select more entities, or else press Enter to join the selected entities)

2 entities joined into 1 polyline, 1 entity discarded from the operation

(Collinear means the entities lie in the same imaginary line; coplanar means the entities lie in the same plane.)

Two 2D polylines are joined into a single

2D polyline - when they are coplanar.
3D polyline - when they are not coplanar and if they are composed only of straight segments
Spline - when they are not coplanar and if at least one of the polylines has a bulged (arc) segment

A 2D polyline and a 3D polyline are joined into a single

2D polyline - when they are coplanar
3D polyline - when they are not coplanar and if the 2D polyline only has straight segments
Spline - when they are not coplanar and if the 2D polyline has at least one arc segment

A line and a circular arc (or a polyline with arcs) are joined into a single

The following pairs of entities are joined into a spline

Even when there are gaps between these entities, the command joins them into a single entity:

Collinear lines - joined into a single line
Coplaner arcs (with same radii and center points) - joined into an arc or a circle
Coplaner elliptical arcs (with same major and minor axes) - joined into an elliptical arc or ellipse,

Circular and elliptical arcs are joined in a counterclockwise direction starting from the source arc.

To join (close) an arc, use the Circle command's turn Arc into circle option.

Options	Description
Select source entity or multiple entities to join at once	Specifies the entities to be joined; you may enter all to select all entities in the drawing, and the program will filter out invalid ones.
Select entities to join	Select more entities, or else press Enter to finish the command and start the joining.

Break - breaks entities.

Explode - reduces complex entities to simpler ones, such as blocks into constituent parts, and polylines into lines and arcs.

Overkill - deletes duplicate entities and overlapping lines, arcs or polylines and unifies partly overlapping or contiguous ones.

PEdit - joins entities into a polyline.
