Each sketch element has a dimension label where you can view and edit the dimensions and measurements of sketches.
In this guide, you will learn about the following:
Edit a dimension
To learn how to edit a dimension using specific input devices, expand the sections below:
Touch or pen
- 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.
- 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.
The types of sketch dimensions are length, diameter, radius, and angle.
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.
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.
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.
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.
