You can use an existing extension line as a dimensioning reference. An extension line is the line that connects the point to the dimension text. If you select an extension line, the baseline dimension for the extension line's dimension is used.
Mouse over the face to see all the possible dimensions.
In cases with many ordinate dimensions, the preview may be slow. Start DS Mechanical using the following command line option to limit the number of dimensions that are shown in the preview. The example specifies '10' but you can set it to any number you wish.
MaxOrdDims=10
The plate shown below has 400 holes but only 10 are shown in the preview.
Click a point to place the dimension line.
If you select a face, all of the possible ordinate dimensions will be created.
You can click multiple points to use the same baseline for those dimensions.
The baseline dimension (0) is displayed or hidden based on which detailing standard is selected in the Detailing options.
Automatic jog points are included if ordinate dimensions are too closely spaced. This helps make them easier to read.
First, establish a simple, oriented dimension. Then use one of the witness lines to set the baseline and orientation of the ordinate dimensions.
In the example above, the leftmost witness line of the existing circle-to-circle dimension was selected to define the baseline.

Click the Select bodies tool guide on the right side of the Design windowArea in the user interface that displays your model or assembly. Also known as Workspace..
Select the solid body or bodies you want to dimension:
If you select a single body, then the maximum horizontal or vertical dimension is created, as shown below.
If you select more than one body, then the dimension is created for both solids and is anchored on the side closest to where you click on the solid. You must click on the Select bodies tool guide before you select each solid, so you click the tool guide and select the first part, then click the tool guide again and select the second part.
In both of the examples below, the upper part was selected near its top. The lower part was selected near its top in the example on the left and near its bottom in the example on the right. The mouse arrows indicate where the lower part was selected. You will see a preview of the dimension when you click the tool guide and hover over the second part.
If you create the dimension in a section view of a drawing sheet, then the dimension is created on the extents of the body that is visible in the section plane, as shown below.
Select the dimension annotation to move, size, or rotate it.
To move the dimension note, mouse over the edge of the box with the Select tool until the cursor changes to , then drag the note.
To size the box that contains the dimension note, drag the handles of the note box (the white circles).
Select the text of the note to reformat it.
(Optional) Right-click the dimension and select text formatting options from the mini-toolbar.
Click to select a tolerance format, then edit the text of the tolerance.
Click to insert a field. You can select a field type and format from the Insert Field window.
Select from the drop-down to insert a symbol.
Click an arrowhead to cycle through alternative leader styles.
You can also right-click an arrowhead and select Arrow Style to select a style for that arrowhead, or select the arrowhead, then select the style for the head in the Properties panelArea of the user interface that displays editable details about the selected object(s). This panel is initially displayed on the lower left side of the screen, but can be moved..
Click the note leaders to modify them.
You can right-click a leader and select Add Jog PointSingle location in the sketch grid. 2-D object that has no height, width, or length. The origin,
an axis, and a vertex are examples of points. Use the Point tool to sketch a point on the sketch grid. Points
are useful as a dimensional reference, for splitting, and for creating a point on a line or curve through which
you want to draw a three-point circle. to add a new point.
To change the distance between a dimension extension line and its reference point on the object, click on the extension line, then hover over the end closest to the object. Drag the red dot to change its distance from the object.
If you cant' see the extension line, hover over the end of the dimension leader, where the line would be. You will see two red dots that you can drag:
Modify the dimension note properties in the Properties panelArea of the user interface that displays editable details about the selected object(s). This panel is initially displayed on the lower left side of the screen, but can be moved.. Modify the:
Arrow Length and Width properties to set the length and width of the arrowheads
Measurement property to change the measurement type. For example, you may want to display the radius of a hole instead of the diameter.
Upper Limit, Lower Limit, and Type of tolerance property to change the format of the dimension and enter upper and lower tolerance values.
Limits and Fits tolerances are supported for Metric units using the ISOInternational Organization for Standardization standards for architectural and engineering drawing,
including guidelines for dimensioning and tolerancing. You can customize the style of your annotations
to conform to ISO standards. See ASME, JIS
Japanese Standards Association standards for technical drawings. You can customize the style of your
annotations to conform to JIS standards. JIS defaults are the same as ISO, except that JIS uses third-angle
views while ISO uses first-angle views. See ASME, ISO.. 286-1 and ISO

You can apply Limits and Fits to metric dimensions for Holes, Shafts, and opposing planar faces (i.e. face normals point toward each other).

If the dimension is created by selecting an edge, the Limits and Fits tolerance type will be available ONLY IF the system can uniquely determine the parent faces. If there is ambiguity, Limits and Fits may not be available as a tolerance type. |
![]() |
Limits and Fits will NOT be available if the dimension (i.e. Basic Size) is outside the range of sizes covered by the standard. |
Limits and Fits tolerances are specified with a letter and a number that refer to a table in the standard.
In the Limits and Fits section of DS Mechanical Options > Detailing, you can set defaults for the properties.
Limits and Fits symbols combine the IT Grade Number and the Fundamental Deviation letter. "IT" is dropped from the Grade Number so only the number is shown. The tolerance size is thus defined by the Basic Size of the part followed by a symbol containing a letter and a number. A Fit is indicated by the Basic DimensionAnnotation on a drawing showing measurement of an edge or face. Use the Dimension tool to add
measurements to your design, drawing sheet, or 3D markup. common to both components, followed by a symbol corresponding to both components with the Internal part symbol preceding the External part symbol.

When you change the size of a dimension that has Limits and Fits tolerances, the Upper and Lower Limits will change according to the limits and Fits tolerance tables.
If you modify the IT number, the tolerance symbol updates accordingly.
The dimension color is changed to Red if it has Limits and Fits tolerance and some of the input parameters are invalid. An example is shown below.
