Join

Joins lines, LW polylines, 2D polylines, 3D polylines, circular arcs, elliptical arcs, splines and helixes at their common endpoints.

The type of the resulting entity depends on the types of the input entities and on their coplanarity.

Accessing the Command

command bar:  join

menu bar:  Modify | Join

toolbar:  Modify |

: join

Prompts you in the command bar:

Select source entity or multiple entities to join at once: (Select one or more entities.)

Select entities to join: (Select more entities or press Enter or right click to join the selected entities.)

BricsCAD reports the result: e.g. 10 entities joined into 2 splines

Command Options

The following rules apply when joining entities:

• Collinear lines will be joined into a single line, even if there are gaps between them.

• Coplanar circular arcs sharing the same radius and center points, will be joined into a circular arc or circle, even if there are gaps between them.

• Coplanar elliptical arcs sharing the same major and minor axes, will be joined into an elliptical arc or ellipse, even if there are gaps between them.

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

Examples:

• Two 2D polylines are joined into:

• a 2D polyline, if they are coplanar.

• a 3D polyline, if they are not coplanar and if they are composed of straight segments only.

• a spline, if they are not coplanar and if at least one of the polylines has bulged segments.

• A 2D polyline and a 3D polyline are joined into:

• a 2D polyline, if they are coplanar.

• a 3D polyline, if they are not coplanar and if the 2D polyline only has straight segments.

• a spline, if they are not coplanar and if the 2D polyline has bulged segments.

• A line and a circular arc are joined into,

• a 2D polyline, if they are coplanar.

• a spline, if they are not coplanar.

• The following pairs are joined into a spline:

• a line and an elliptical.

• a spline and an elliptical arc.

• a helix and a circular arc.
