Splines

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 Sketch ribbon, select one of the Spline tools.
   
   
2. Select a face or plane as the sketch plane.
3. To sketch a spline:

   To sketch this	Do this
   Spline Through Points	Click to place each fit point of the spline.
   Spline Using Control Points	Click to place each control point of the spline.

4. Right-click and mouse through the check mark to exit, or double-right-click.

Reposition, resize, or apply a sketch constraint.

1. Double-click the spline to enter edit mode.
2. Edit the spline:

   To	Do this
   Add a point	Select the spline, then hover over the curve between two points until you see a reference point with a + icon. Click on the reference point to add an additional point.
   Reposition a point	Drag the point, or Select the point, then enter coordinates to specify the position.
   Reposition a line	Select the line and drag it, or Reposition the end points.
   Resize a line	Drag an end point, or Select the line, then enter a Length in the microdialog.
   Select a chain of segments	Select a sketch segment, then double-click it to select the entire chain of segments.
   Cut, copy, or paste the sketch curve	Right-click a sketch curve, then select Cut, Copy, or Paste on the context menu.
   Apply a sketch constraint	Right-click a sketch curve, then select a sketch constraint on the context menu.
   Convert a sketch curve into construction geometry	Right-click a sketch curve, then select Construction. Construction geometry is used as a reference to line up or define other geometry.
   Hide dimensions	Deselect Show dimensions in the Preferences.

3. Right-click and mouse through the check mark to exit, or double-right-click.
