Make a tube/pipe with FreeCAD

Why I Chose FreeCAD

I chose FreeCAD because it runs smoothly on my old laptop compared to AutoCAD.

Getting Started

There are two methods to create a pipe in FreeCAD that I’m familiar with.

Method 1: Using Draft and Sketcher

  1. Open FreeCAD:

    • Create a new document (Ctrl + N).
  2. Create a Circle:

    • From the dropdown menu, select Draft.
    • Draw a circle. You can adjust its location and radius later using the options in the left corner box.
  3. Set the Viewing Plane:

    • You are currently in the YX plane (visible in the right corner).
    • Press 0 to switch to the 3D view, and then press 1 to view the object in the XZ plane.
  4. Create a Sketch:

    • Select Sketcher from the dropdown menu.
    • Create a new sketch and draw a circle with its origin at the center.
    • Use the Circle Constraint to set its radius.
  5. Draw a Perpendicular Line:

    • Create a new sketch on the XZ plane.
    • Draw a straight line from the origin, and set the constraints.
  6. Sweep the Circle Along the Line:

    • Choose Part from the dropdown menu and rename the circle and line.
    • Select Sweep and choose the circle as the profile.
    • Set the Sweep Path to the straight line and click Done.
  7. Create a Pipe:

    • To create a pipe, select the top and bottom surfaces of the cylinder.
    • Press 0 to choose the top surface, then press 5 and Ctrl to choose the bottom surface.
    • Click the Thickness icon and press OK. Your pipe is now complete.

Method 2: Using Create Primitives

  1. Open FreeCAD:

    • Create a new document (Ctrl + N).
  2. Select Part:

    • From the dropdown menu, choose Part.
  3. Create a Cylinder:

    • Select Create Primitives and choose the cylinder shape from the left-hand side.
    • Set the radius and height for your cylinder.
  4. Follow Steps from Method 1:

    • Repeat the steps for sweeping and setting thickness from Step 14 in Method 1.

Done!
