Smart Attributes
Smart attributes can be defined to link an asset components attribute to the underlying spatial feature, and setting its value to the length or area of said geometry. Once an attribute has been defined as a smart attribute for a given classification, its value can no longer be set by end users. Rather, any changes to the underlying spatial feature will trigger an update of the fields value.
In order to be defined as a smart attribute, the form field must be marked as required.
The definition of a smart attribute, like cost unit formulas, must be done via the classification screen. This is because form definitions can be shared across multiple classifications, and it may not be correct for an attribute to be ‘smart’ for all of the classifications that rely upon it.
