Update: January 19, 2019
FreeCAD 0.17
  1. Click [File]-[New] in menu bar and create new document. Switch workbench to Part Design workbenchPart workbench.

  2. Select New SketchSketcher_NewSketch in toolbar and select XY plane as sketch plane on the dialog. Click OK to create a new sketch plane.

    Create Sketch Creates sketch plane
  3. Select PolylineSketcher_CreatePolyline in toolbar and draw a "H" shape on the sketch plane as shown in the following figure.

    Create Circle Draws sketch
  4. Select two end points and select Coincident constraintConstraint_PointOnPoint in toolbar to connnect the lines.

    Create Circle2
  5. Select each segment of line and apply constraints as shown in following figure. In this operation, we use Horizonal constraintConstraint_Horizontal, Vertical constraintConstraint_Vertical, Vertical Distance constraintConstraint_VerticalDistance, Horizontal Distance constraintConstraint_HorizontalDistance, Equal Length constraintConstraint_EqualLength and other constraints.

    Create Circle3 Apply constraints to the sketch
  6. Click Close on Task tab to exit sketch editing mode.

  7. Select the created sketch model tree and execute RevolutionPartDesign_Pad to execute rotation extruding. Enter angle of rotation on the dialog and click OK.

    Revolve-task Revolution dialog

    Rotation axis can be selected from followings.

    • Sketch plane's Horizonal axis
    • Sketch plane's Vertical axis
    • 3d coordinate-system's X axis
    • 3d coordinate-system's Y axis
    • 3d coordinate-system's Z axis
    • Construction line in the sketch (select by click on 3D view)
    • Edge of exisiting shape (select by click on 3D view)

    Revolution operation results are as follows.

    Revolve360 Rotates 360 degree
    Revolve230 Rotates 230 degree
