Smart Dimension command

Places a dimension on any single element, between any two elements, or between elements in different drawing views of the same model. The dimension types that are available with the Smart Dimension command depend on the elements you select.

When placing dimensions between drawing views, the views must share the same view plane. For example, you can add a dimension between an edge in a front view and an edge in a detail view with the same front orientation, but not between a front view and a side view.

Selecting elements

You can use Smart Dimension to place a dimension on the following single elements:

You can also use Smart Dimension to place a dimension between any two elements, such as:

Using keyboard options

Before you click to place the dimension, you can use the following keys to affect the dimension that is created. The options that are available depend upon what, and how many, elements you select. Refer to the specific prompts displayed on PromptBar as you select elements.

Keyboard options

Result

A

Changes between a linear dimension and an angular dimension.

B

For PMI, changes the dimension orientation back to the previous dimension plane in sequence.

D

Changes between a radial dimension and a diameter dimension.

I

For PMI, selects an intersection point.

N

For PMI, changes the dimension orientation to the next dimension plane in sequence.

Shift

Alternates between:

  • The horizontal or vertical distance between elements (A).

  • The minimum distance (B).

Alt

For a radial or diameter dimension, adds a projection line extension to the dimension.

Default appearance

With the Alt key

Q

Turns automatic locate off and on so you can select a different element to dimension to.

Specifying dimension format and appearance

Use the Smart Dimension command bar to format all aspects of the dimension before you place it. For example, you can:

You can use the Properties command to open the Dimension Properties dialog box to specify other aspects of dimension formatting. For example, you can specify the length and size of dimension lines and projection lines (on the Lines and Coordinate tab), and the gap between the dimension text and the dimension line (on the Spacing tab).

Adding jogs

You can use Alt+click to add one or more jogs to the horizontal or vertical dimension projection lines of linear, diameter, and distance between dimensions created with the Smart Dimension command.

You can remove a jog on an existing dimension by holding the Alt key while you click a jog key point, and you can remove all jogs on a selected dimension line or projection line using the Jog button on the command bar.

You also can drag the segment or the handle points created by the jog to change the length and orientation of the jog lines.
