Exposed Area parameter in Surface Schedules

Exposed Area is the part of an element’s surface that would be covered by a paint bomb. In the follow diagram, the dark blue area is considered as “Exposed”, the light blue areas are considered as “Covered”.

You can define exactly what counts as exposed, using the Reduced Exposed Area control in the Scheme Settings of your Surface List.

Reduce Exposed Area

1.In Scheme Settings, Fields panel: find the Exposed Area (By Criteria) field.

2.Click the button to open the Reduce Exposed Area dialog box.

3.Define which elements are covering elements (that is, they should cover up other element surfaces).

For example: normal construction elements are covering elements: if they overlap a wall’s surface, that wall’s surface is covered, and the wall’s exposed area is reduced accordingly.

However, some elements are usually not covering elements. In this example: objects, lamps and zones should not affect a wall’s exposed area, so they are not listed here:

Hide Surfaces with Zero Exposed Area: This is checked by default. It means that unexposed areas, with zero visible area, are not shown in the schedule.
