Best answer for this question, what is 3D polyline? A 3D polyline is a connected sequence of straight line segments created as a single object. 3D polylines can be non-coplanar; however, they cannot include arc segments.If you want to join a 3D polyline with another one, or with a spline, you can use the command JOIN. This function joins also two or more 3D polylines into one, or joins a 3D polyline with a spline to a new spline curve. You can use JOIN for 3D lines (geometry) also in AutoCAD LT.
