Area calculation standards are .NET plug-ins that implement a set of rules to define offsets for the net, usable, and gross boundaries of spaces in AutoCAD Architecture 2023 toolset. When a plug-in is loaded into the software, it will be available to be applied to a drawing . Only one area calculation standard can be applied to a drawing. If the boundary offsets of a space are set to By Standard, the calculation standard that is currently assigned to the drawing will be applied to create the boundary offsets.
Boundaries generated by basic area calculation standard
The API (Application Programming Interface) that is used to implement those plug-ins is available for 3rd party developers as part of the AutoCAD Architecture 2023 toolset .NET API.
