In most cases, you will need more control points than fit points to define a given shape. You can think of a control point as applying ‘tension’ to the spline in a given direction: pulling a point further away increases the tension on the curve in that area, and pushing it closer relaxes that tension.Ģ. Unlike fit points, which define points that the spline must pass through, control points just define the underlying frame used to calculate the curve. As shown above, a control point spline will (usually) not pass through the selected points besides the first and last points. These are now presented in a Spline flyout in the Sketch tool menu.Īs you start to use these two tools together, there are two key differences to keep in mind between fit point splines and control point splines:ġ. the spline ‘fits’ to the specified points). Since we’ll now have two spline commands, we’re renaming the previous Spline tool to “Fit Point Spline” (i.e. If you’ve ever used Box Display or Control Frame Display in the Sculpt workspace, you’re essentially seeing the same concept there: you manipulate a simple polygonal control frame, and this drives the resultant smooth shape of the surface. You select a series of points, and these points will define a ‘control frame’ from which a smooth curve is derived.

With this tool, you select a series of points, and Fusion will create a smooth curve that passes through them.Ĭontrol point splines offer an alternative approach for achieving the same result.
Until now, this requirement has been met by the existing Spline command.
