Analyzing Grade

Grade objects can be used to analyze the slope objects in a drawing and identify critical slopes. Grade objects that are outside specified slope or elevation ranges are highlighted or selected.

To perform a grade analysis:

1. Click the Grade tool from the appropriate tool set:

●    Designer and Landmark workspace: Site Planning tool set

●    Architect and Spotlight workspace: Building Shell tool set

2. Click Preferences from the Tool bar. Alternatively, click Settings from the Object Info palette of a selected grade object.

The Grade Settings dialog box opens. Click the Global Settings tab and specify the grade analysis parameters.

Global attribute display of the slope indicator is described in Specifying Global Grade Object Preferences

►    Click to show/hide the parameters.
