Spline Creation

Click the Spline command button on the ribbon to activate the Spline command. If there is no Sketch Plane on page 138 currently active, you are prompted to select one.

Spline CreationWhen you activate the Spline command, you can define fit points by clicking the mouse, or by typing the values into the Heads-Up Display (HUD) text boxes. This helps you to create more precise geometry. You can press the Tab key to navigate from one HUD text box to another.

Spline CreationIf there are existing sketch geometries on your Sketch Plane, you also receive feedback on points that lie on other sketch entities, midpoints, and Grid snap points. See Sketch Inferencing on page 162 to learn more.

Although you cannot define explicit constraints while creating Sketch entities, some constrains are implicitly detected when creating/editing Sketch entities. See Sketch Constraints on page 169 to learn more.

You can create a spline that is tangent to another line or spline by clicking the start or endpoint of the line or spline and dragging away from it. You see a tangent line indicator when the constraint is inferred.

Spline CreationYou can create open splines as well as closed splines. You can complete the creation of an open Spline entity by double-clicking at the last point. To create a closed Spline, click the start point of the current spline entity – it also is defined at the endpoint. The current entity creation is completed and you can start creating a new entity.

Spline CreationNote: It is possible to create self-intersecting splines (like a figure-8) using the spline command, but such non-manifold entities are not supported by the Sketch Profile on page 171 recognition system, and may cause undesirable results.

To exit the Spline command, press the Esc key or pick any other command. Any Spline that is currently in a preview state is discarded.
