Creating a Dimension Annotation

  1. Click the arrow under the Dimension tool and select Dimension.
  2. If you are creating a dimension in 3D, click a face to create an annotation plane on which to place the dimension.
    Mouse over the faces of your design to preview the eligible annotation planes. (In Sketch and Section mode, the sketch grid defines the annotation plane.) If multiple objects occur at your cursor location, use the scroll wheel or arrow keys to highlight each one.
    To create an annotation plane for a cylindrical face, select the cylinder's axis.
    If you need to change the annotation plane, right-click and click Select New Annotation Plane from the context menu and select a new annotation plane.
  3. Click an edge or face.
    Where you click a circle determines whether you will measure from the circle's center, near, or far edge. To select the center click the top, bottom, left, or right side of the circle.
  4. Mouse over your design to preview the possible dimensions.
  5. Click a second object if you want to dimension between two objects.
  6. (Optional) Select a dimension orientation in the Options panel. You can also select the orientation for the first and second reference.
  7. Click to create the dimension.
