Details and Annotations
This topic describes the new and enhanced features for details and annotations in Revit Architecture 2009.
Baseline and Ordinate Dimensions
You can create and place baseline and ordinate linear dimensions in your project. Baseline dimensions are
multiple dimensions measured from the same baseline. Ordinate dimensions measure the perpendicular
distance from an origin point (called the datum) to an element.
Baseline and ordinate dimensions are exported to CAD formats.
For more information, see
Baseline and Ordinate Dimensions
on page 219.
Formatting Permanent and Spot Dimensions
You can add bold, italic, underline, and width formatting to permanent and spot dimensions. Access these
formats in the Type Properties dialog for the dimension.
Permanent Dimension Placement Enhancements
You can dimension to the following:
■
Intersection points of lines, grids, reference planes, and location lines (for walls).
■
The center of arcs, when placing a linear dimension. The center mark of the arc does not need to be
visible to dimension to it.
Adding Text to Dimension Values
You can add supplemental text above, below, or to the left or right of a permanent dimension value. You
can also replace permanent dimension values with text. See
Overriding Dimension Text
on page 224 and
Replacing Permanent Dimension Values with Text
on page 224.
Spot Elevation Enhancements
■
You can display the top and bottom elevation of elements with a definite thickness. Top and bottom
elevations are available for elements in plan views. See
Spot Elevations
on page 227.
■
You can place spot elevations with a leader, a leader and a shoulder, or without a leader. See
Placing a
Spot Elevation Dimension
on page 228.
■
You can add supplementary text to spot elevations. See
Adding Supplementary Text to Spot Elevation
Dimensions
on page 229.
■
The Rotate with Component type property is now available for spot elevations. This allows spot elevations
to maintain their location relative to the referenced element when the element is rotated. You can specify
this type property in the Element Properties dialog for the spot elevation.
