AutoCAD Tutorial 20: Convert Line to Polyline

by Tutorial45

While we are much more focusing on AutoCAD basics here, it is necessary to learn how you can convert LINE to Polyline and vice versa.

This might not make sense to you now but will surely come in handy when you will come to a point where you need to convert a line to a polyline. An example where this will be needed is when you are working on a project where you need to join a series of the line to make it a single object and use the resulting polyline as a PATH.

A concrete example:

Let’s say we need to create an ARRAYPATH in AutoCAD, if we create our path using the LINE command, the path will be made of many line segments, To use this command you need to have all lines converted to a single object. You will then need to convert Line to Polyline.
