How to Join 3D Line/Polylines Segments in CADPower? || CP_3DJ Command

The CP_3DJ command joins 3D segments (lines or polylines) and combines them into a 3D polyline. The PEDIT command does not allow joining of 3D segments. This command fills the need by allowing the Join subcommand to be applied on 3D polyline segments or lines. The segments to be joined must be exactly touching each other.

Once the command has been issued, the prompts that follow are similar to the PEDIT command. You are prompted to select polylines. If a line has been selected, you are prompted to convert it into a polyline. Then you select the objects to join. All touching segments are joined to the first segment resulting in a joined 3D Polyline.

Select 3d polylines/lines to join (or ENTER to select by layer[s]):
Select objects: (do so)

If you are selecting multiple layers for processing, CP_3DJ will join them individually in their respective layers. They will not be joined across different layers except if they are selected explicitly from the command line.
