# Curvature

Create curvature continuous transitions between sketch splines (and conics) and surrounding geometry.

Shortcut: shift+u

In the Sketch toolbar:

The Curvature sketch tool allows you to create curvature continuous transitions between sketch splines (and conics) and surrounding geometry.

Click the Sketch feature on the feature toolbar to create a new sketch. Select a plane in the graphics area.

Create geometry that you would like to be curvature continuous. In this example, a line and spline are drawn. Once drawn, select the line and spline. Then select the Curvature sketch tool from the toolbar. The geometry is automatically transitioned into a continuous curve. Alternatively, first select the Curvature sketch tool from the toolbar and then select the geometry, in this example, the line and the spline.

## Steps

To ensure that the splines or conics are curvature continuous:

- Select the geometry involved.
- Click .
