Subject: Drawing a spline

To draw a spline   

   1   Do one of the following to choose Spline ():

   On the ribbon, choose Draw > Spline (in Draw) or Draw 3D > Spline (in Curves).

   On the menu, choose Draw > Spline.

   On the Draw toolbar, click the Spline tool.

   Type spline and then press Enter.

   2   Specify the first point of the spline.

   4   Specify as many more points as you want.

   5   When you have finished, press Enter.

Select a line to convert it to a spline.
The Convert to NURBS command is typically used to convert solids and surfaces to NURBS surfaces, but it can also be used to convert two-dimensional entities (for example, lines, polylines, arcs, circles, etc.) to splines. For more details, see Convert­ing surfaces and solids to NURBS surfaces.

You can add tangents to the spline, which are lines that give it shape.

To add tangents to a spline

   1   Specify the starting tangent point.

   2   Specify the ending tangent point.

 

 

 

Initial spline and resulting spline with starting tangent point (A) and ending tangent point (B).
