The lines are created (in a .dxf) by a GPS unit in the field, and represent tracks needing to be mapped. Typically we would drive out a track and then drive back on the same track; this gives me two 3d polylines. Because of GPS errors it better practice to log the roads/ tracks twice. The lines can have from 2000 to 10000 vertices, so manually drawing is not an option. Any ideas? Thanks
Create a 3d object away from the two 3d objects you need to join, type SUBTRACT, select the two 3d objects as regions to subtract from, then select the created 3d object away from the two as the region to subtract to...press enter
@James Maeding Hi.I'm using V21-2.02-01.I've drawn 2 3DPOLY that have 3 vertex each, and with different Z values, but one vertex for each one of them was the same( X,Y,Z).I used the JOIN command and it did joined them to one entity, kipping the joined entity as a 3DPOLY.I did another test, Drawing PLOYLINE (x,y and elevation) and a 3DPOLY with different z values and one joint vertex, and when using the join command the joined object turned in to 3DPOLY and kept the z values (Elevation of the 2DPOLY turned to Z).
Try to implement this small trick into your work and you will see a great improvement in speed and quality of your drawings! If you want to learn more tricks concerning Polylines you can look at those:Create Polyline around the Outside of Multiple Objects!Edit Vertexes and use Linetype Polylines!Coordinates of polyline?

This application joins and cleans-up polylines and line entities to create closed boundaries and to close gaps not seen visibly. The app includes 9 functions; each with additional settings and sub-routines for quick and automatic joining, trimming, cleaning and closing. With 9 user-defined settings.1.

There are various polyline types in AutoCAD, the most common of which is usually the LWPolyline (lightweight polyline). It can be confusing because the LWPolyline and the old Polyline entity used way back in the early days of AutoCAD are both shown as a "Polyline" in the Properties window. Chances are though, unless you're working on some nasty generated drawing, you're probably using LWPolylines.
The third polyline type is the 3D polyline, which as the name implies is a 3D version. Both the LWPolyline and the Polyline only permit the creation of geometry on a flat plane (UCS), but the 3D polyline allows points anywhere in 3D space.
Converting between the various types therefore has obvious difficulty, because going from 3D to 2D means you're going to have to remove some of the 3D information from the polyline, and AutoCAD could interpret how to do this in many ways. Therefore historically there have not been native commands to convert between the polyline types.
The FLATTEN command is an option for making the polyline flat (i.e., visibly the same as before, but drawn as a 2D line on whatever UCS you're working on). I have had troubles with FLATTEN in the past however, because I think it does some odd stuff sometimes with merging lines and approximating... so I tend to avoid it where possible.
the tool with then ask you to select your first line segment - which if drawn using the line tool will be a single line - it will then ask to convert this segment to a polyline as shown below - say Yes 2ff7e9595c
