Summary
CP_3DJ: Command is a tool that automatically connects selected 3D Polyline objects by merging them at their endpoints. This simplifies the process of creating continuous shapes from separate segments in 3D Polylines.
CADPower -> Polyline Tools -> Join -> Join 3D Polylines
The CP_3DJ command joins 3D segments (lines or polylines) and combines them into a 3D Polylines. 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.
