Dimension
You can dimension a planar sketch in the same way as with the Distance, Angle, Diameter or Radius functions.
- Select Sketch | Dimension.
- Select the element being dimensioned, such as a line, circle or a pair of points.
- Select the position of the dimension.
- Edit the data in the Edit constraint dialog box.
- Select OK.
- Add more constraints by repeating steps 2-5 or finish adding constraints by pressing the ESC key or the middle mouse button.
Note:
- You can dimension the diameter of a part which is rotationally symmetric.
- The dimension will change between distance and diameter when you move the cursor over the rotation axis before positioning the dimension.
- The type of one of the lines must be Rot.Axis.
- This works for both the Distance and the Dimension constraints.
- After positioning the dimension you can drag the it elsewhere and it will remain a diameter dimension.
