Each sketch element has a dimension label where you can view and edit the dimensions and measurements of sketches.

## Edit a dimension

- Click the element to select it.
- Hover your cursor over the dimension label.
- Use your keyboard to type the value of the new dimension.
**Optional:**You can click the dimension label to open the numpad and use the calculator to calculate the final value of the dimension.

## Dimension Types

The types of sketch dimensions are length, diameter, radius, and angle.

### Length

The length is the distance between two endpoints such as a line.

You can define the length of two endpoints with the following distance types:

**Absolute**– Distance between the two endpoints of a line.**Horizontal**– Distance between the two line endpoints relative to the horizontal axis.**Vertical**– Distance between two line endpoints relative to the vertical axis.

To define a distance type, select the **Distance Type **badge that appears beside the dimension label.

### Diameter

The diameter is the distance between two points in a circle that passes through the center.

You can define the diameter of circles.

To define a circle by its diameter, your **Circular Annotation** in Settings or Preferences [link to article] must be set to **Radius and Diameter**.

### Radius

The radius is the distance between the center of a circle to any endpoint. For circles, the radius is half of the diameter. Meanwhile, ellipses have two radii: major and minor, where the major is the larger of the two.

You can define the radius of circles, arcs, and ellipses.

To define a circle by its radius, your **Circular Annotation** in Settings or Preferences must be set to **Always ****Radius**.

### Angle

The angle is formed by the common point of two intersecting lines.

You can define the angle of the following sketch elements:

- Between two connected or unconnected lines
- Between two connected splines or arcs
- Between a connected line and arc or spline

To change the angle between two elements, select them and then enter the new value of the angle.

## Edit a dimension

- Tap the element to select it.
- Select the dimension label.
- Use the numpad to input the new dimension, or use the calculator to calculate the final value of the dimension.
- To apply the value, tap the check mark.
