Join Polyline

 
Connects two or more separate objects, connected at their endpoints, into a single-object polyline. Objects that overlap cannot be joined.

Note: If you want to create a polyline from a partial chain of segments, or if you have overlapping objects, see Chain Polyline.

1. Select the tool.
2. elect the first object you wish to include in the polyline. Selection order is not important.
   
3. One by one, select the remaining objects to include.
   
4. Select Finish from the local menu or Inspector Bar.

The objects now comprise one object, as you can see in Select mode.

As of TurboCAD 2015 when you are joining a set of all Beziers the resulting object will be a Bezier.

Local menu options:

 
Delete Original Objects: Removes the original segments, leaving only the polyline.

Auto joining: Automatically selects all objects connected to the selected object. This option must be active before selecting any segments. You can select any object in the chain, not only the first or last object. If more than one segment branches from an endpoint, the chain will stop.

3D Polyline: Enables you to include objects located on different workplanes.
