Let get started

We will use the command called SWEEP, we could decide to use the EXTRUDE command too, but the SWEEP command makes it easier for us.

In order to use the SWEEP command to create a pipe, we need a circle representing the cross section of our pipe, and we need the path. The path has to be the perfect shape and length of the pipe we are seeking to create. So you want to be careful here by designing it well.

We will use the POLYLINE command to draw the path.

As randomly as it can be we will create a path, up and down, right and left.

Yea, you noticed it. I created a circle which eventually represent the cross section of our pipe. Now we are good to go. We have all our requirement in place to create our pipe. A path and our circle.

You need to make sure that the path is one object, if it is not, you need to unite all those lines together for them to constitute only an object.

Joining many lines to form a POLYLINE (You should follow this only if your path is formed by many short segments)

  1. Write PEDIT and Press ENTER
  2. Select Polyline or [Multiple]: write “M” and press ENTER
  3. Select Objects: Select all lines
  4. Convert Lines, Arcs and Splines to polylines [Yes/No]? <Y>:  Press ENTER
  5. Enter an option [Close/Open/Join/Width/Fit/Spline/Decurve/Ltype gen/Reverse/Undo]: write “J” and press ENTER
  6. Enter Fuzz distance or [Jointype] <0.000>: Press ENTER
  7. Press ESC on your keyboard.

The part in bold is the message you are receiving from the command window from AutoCAD.
