Splines

Sketch and edit a spline.

Sketch a Spline

Sketch two types of splines: (1) a smooth curve that passes through the fit points or (2) a smooth curve that passes near, but not through, the control points.

  1. On the ribbon, click the Sketching tab.
  2. Click one of the Splines icons.

  3. Set the sketch plane:
    • Click one of the default sketch planes: Top, Front, or Right.
    • Click the planar face of an object.
  4. Optional: In the guide bar, type a Degree, and then press Enter.
    Type a higher degree for a smoother curvature. The default degree is 3.
  5. Optional: To create a closed spline, in the guide bar, click Closed.
  6. Sketch a spline:
    To sketch this Do this
    Spline

    Click to place each fit point of the spline.
    Control Points Spline

    Click to place each control point of the spline.
  7. Right-click and mouse through the check mark to exit, or double-right-click.

Edit a Spline

Reposition, resize, or apply a sketch constraint.

  1. Double-click the spline to enter edit mode.
  2. Edit the spline:
    To Do this Note
    Add a point Click the spline, and then click Add Point.  
    Reposition a point
    • Drag the point.
    • Click the point, and then type the x, y, and z coordinates.
     
    Add weight to a point Click a control point, and then add a Weight.  
    Reposition a line
    • Click the line, and then drag it.
    • Click the line, and then type an Angle.
     
    Resize a line
    • Drag an end point.
    • Click the line, and then type a Length.
     
    Modify the degree Click the spline, and then type a Degree.  
    Select the chain or endpoints
    1. Select one or more sketch curves.
    2. Right-click the selection, and then select Select the chain or Select the endpoints.
     
    Cut, copy, or paste the sketch curve
    1. Select one or more sketch curves.
    2. Right-click the selection, and then select Cut, Copy, Paste, or Paste without constraints.
     
    Apply a sketch constraint Click the sketch curve, and then select a sketch constraint on the microdialog. To hide constraints, right-click, and then deselect Show constraints.
    Convert a sketch curve into construction geometry Click the sketch curve, and then select Construction. Construction geometry is used as a reference to line up or define other geometry.

    To hide construction geometry, right-click, and then deselect Show construction geometry.

    Hide dimensions Right-click, and then deselect Show dimensions.  
  3. Right-click and mouse through the check mark to exit, or double-right-click.
