Geometric Dimensioning and Tolerancing Note

The Geom Dim and Tol Note tool is used to insert a notation symbol and text specifying the dimension of round, square, counterbore, and/or countersink holes, and unit ratio for conical and/or flat tapers. Alternatively, a depth symbol and associated text can be inserted.

 

To insert a geometric dimensioning and tolerancing note:

1.	Click the Geom Dim and Tol Note tool from the Dims/Notes tool set.

2.	Click in the drawing to insert the note. Click again to set the rotation of the object.

If this is the first time the object has been inserted in this session, the Object Properties dialog box opens. If the Attributes palette has not been set to use end markers, select the marker style, size, and angle from the Object Properties dialog box.

3.	Specify the geometric dimensioning and tolerancing note parameters in the Object Info palette.

 

Parameter	Description
Precision	Select the decimal place rounding value for the hole size and depth
Note Type	Select the style of the note marker
Hole Size/Taper	Enter the diameter for round, square, counterbore, and countersink holes; enter the unit ratio for conical and flat tapers
Tolerance	Sets whether the hole size/taper has a single, double, limited, or no tolerance
Top/Bottom	Enter the value that is added to or subtracted from the base dimension to determine the upper/lower limit of the dimension
Depth/Angle	Enter the depth for round, square, and counterbore holes (if the depth is zero or less, it is not displayed); enter the angle for countersink holes
Tolerance	Sets whether the depth/angle has a single, double, limited, or no tolerance
Top/Bottom	Enter the value that is added to or subtracted from the base dimension to determine the upper/lower limit of the dimension
Leader	Enter text to display before the dimension
Trailer	Enter text to display after the dimension
Leader Line Position	Select to place the dimension leader line to the right or left side of the object

Once the geometric dimensioning and tolerancing note has been placed, its marker can be selected from the Attributes palette (see Marker Attributes).

4.

If desired, create and set a leader line using the 2D Selection tool. Click the symbol control point. Crosshairs display to indicate the leader endpoint position. Click at the desired endpoint location; the leader line is drawn with the marker style, size, angle, and the shoulder length specified in the object preferences.
