A variety of enhancements were made to dimensions in Draft, PMI, and in sketches.

• Specifying tolerance

  There now are two tolerance dimension types that you can select from the command bar when you want to specify a tolerance type of dimension.

  • Tolerance (unit)

    Use this option when you want to specify a unit tolerance, such as mm or inch, and when you want to apply formatting to the layout and justification of the tolerance values.

    Example:

    • You can type 1/8, and it converts to .125.

    • For angular tolerance, you can enter numbers in degrees-minutes-seconds.

    You also can type unit tolerance into the text boxes on the dimension command bar, and use the new Upper Tolerance Sign (+) and Lower Tolerance Sign (-) buttons to specify that the values are positive or negative.

    

  • Tolerance (alpha)

    Use this option when you want to enter any alphanumeric string for the tolerance value. This is the way the Tolerance option worked previously.

• Dual unit formatting

  Now you can display primary and secondary units side by side instead of vertically. You can do this using the following options on the Secondary Units tab (Dimension Style and Dimension Properties):

  • Position

    Below primary or Beside primary

  • Justification

    Left, Center, or Right

• Specifying round-off

  Now there are independent round-off settings for primary units and secondary units. Previously, only secondary unit round-off was available.

  You can specify round-off:

  • Using the new Round-off dialog box.

  • On the Units tab and the Secondary Units tab in the Dimension Properties dialog box and the Dimension Style dialog box.

• Specifying a dimension axis

  • Now you can select a centerline to define a dimension axis.

  • For easier identification, the dimension axis is highlighted and displayed as a dashed line instead of a solid line.

  • You can redefine an existing dimension axis by clicking the Dimension Axis button again and choosing a different line. Dimensions that were placed using the original dimension axis readjust to the axis you select.

    Previously, the dimension axis could not be changed.

    You can redefine a dimension axis to correct dimension rebind failures when a drawing view is update.

• Placing chamfer dimensions

  Now you can place a chamfer dimension using two keypoints.

  Example:

  

  Previously, you could only place a chamfer dimension by selecting two linear elements.

• New double arrow terminator types are available on the Terminator and Symbol tab (Dimension Style and Dimension Properties).

• Radial/Diameter dimension shortcut keys

  Before you click to place a radial or diameter dimension, you can:

  • Use the D key to change from a radial dimension to a diameter dimension, and from a diameter dimension to a radial dimension.

    

  • Press the Alt key to add a projection line extension to the dimension.

    Default appearance	With the Alt key

    After placing a radial dimension inside an arc or circle, you can drag the edit handle on the extension line to lengthen or shorten it.

    

• Diameter half or full display

  For diameter or symmetric diameter dimensions, you can use the Diameter Half/Full button on the command bar to change the dimension display between half and full.

  Half	Full
  Note: For a Half diameter display, you can use the Extension option in the Projection Line section of the Lines and Coordinate tab (Dimension Style and Dimension Properties dialog box to specify the initial amount that the dimension line extends beyond the center of the circle. You can modify this by selecting the dimension and dragging the handle.
