Joining Entities

Command: JOIN

The Join command 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.

To join colinear lines

When you join colinear lines, the farthest endpoints remain at their existing locations; BricsCAD draws a new line between these points.

1. Do one of the following:

   • Click the Join tool button () on the Modify toolbar.
   • Choose Join in the Modify menu.
   • Type join in the command bar, then press Enter.

   You are prompted: Select source entity or multiple entities to join at once:

2. Select the lines.
   You are prompted: Select entities to join:

3. Right click or press Enter.
   The lines are joined.

To join two arcs

Coplanar arcs, sharing midpoint and radius, are joined counterclockwise, therefore the result depends on the selecting order.

1. Do one of the following:

   • Click the Join tool button () on the Modify toolbar.
   • Choose Join in the Modify menu.
   • Type join in the command bar, then press Enter.

   You are prompted: Select source entity or multiple entities to join at once:

2. Select the first arc.
   You are prompted: Select entities to join:

3. Select the second arc and press Enter.
   You are prompted: 2 entities joined into 1 arc.
   
   
   Joining two arcs: start situation (left) and result when selecting A first (middle) or B first (right).

   NOTE	If more arcs share the same center point and radius, you can select them in step 3. Press Enter after selecting the last arc.
