1   Select the Spline tool from the Sketch ribbon group.

2   (Optional) Dimension the first point of the spline relative to another sketch object.

3   Click or press Enter to set the first point of the spline.

4   (Optional) Dimension the spline by entering the coordinate distance from the start point to each point, or dimension each point relative to another sketch object.

5   Click or press Enter to set the next points of the spline.

.

6   End the spline.

You can:

• Double-click to set the end point of the spline.

• Right-click and select Finish Spline.

• Press Esc.

• Connect the end point to the start point.

• Click any tool (except the Clipboard and Orient tools).

You can also:

• Move a spline

• Edit a spline

• Add spline points

• Remove spline points

• Create a closed spline

1   Click the Select tool in the Edit ribbon group.

2   Mouse over the spline to highlight the spline and display its defining points.

3   Click anywhere on the spline except for the defining points, and drag it to move it.

1   Click the Select tool in the Edit ribbon group.

2   Mouse over the spline to highlight the spline and display its defining points.

3   Click and drag on any internal point to move it, leaving the other spline points fixed in space.

4   (Optional) Edit the dimensions associated with that point.

5   Click an endpoint to display its endpoint control handle.

The endpoint control handle is a light blue point at the end of a dotted line extending outwards from the end of the spline. In some cases, these endpoints may be located some distance away from your sketch. Zoom out from the sketch until you can see the endpoint control handle.

If another line, arc, or spline shares that endpoint, the endpoint influence may snap into tangency with that sketch entity. To adjust the endpoint influence in this case, move the mouse a short distance away from the endpoint to display the endpoint control handle.

6   Drag the endpoint control handles to change the influence of that endpoint on the shape of the spline.

The amount of the endpoint's influence can be controlled by dragging the endpoint control handle closer to or further away from the endpoint.

1   Click the Select tool in the Edit ribbon group.

2   Mouse over the spline to highlight the spline and display its defining points.

3   Right-click anywhere on the spline except on the defining points, and select Add Spline Point to create another spline point at that location.

1   Click the Select tool in the Edit ribbon group.

2   Click the spline to highlight it and display its defining points.

3   Right-click the point you want to remove and select Remove Spline Point.

The spline adjusts to accommodate the removal of the point.

You can create a closed spline in the following ways:

• When drawing a spline, end it on the start point.

• When editing the spline, drag one endpoint on top of the other point.

Once you have created a closed spline, you cannot edit it into an open spline.
