Abstract: Embodiments of the invention provide a CAD application that allows users to establish, maintain, and synchronize project standards for style definitions and display settings across multiple drawing files that are part of a design project. The CAD application also allows users to specify how changes to a project standard should be synchronized across the drawing files associated with a given design project. A synchronization setting may be manual, semi-automatic or automatic.

Abstract: Embodiments of the invention allow users to generate and maintain space objects in a computer-aided design model representing regions bounded by a set of drawing elements included in the model. The space object contains the geometry of such a bounded region and may be used to calculate values such as area and volume associated with the region. Additionally, each space object may be associated with the set of drawing elements bounding the region represented by the space object such that any changes to one of the associated bounding elements causes the geometry of the space object to be updated automatically to reflect these changes. Areas and volumes calculated from the space object geometry may conform to established standards regarding the calculation of gross, net and useable areas of a building or other structure.

Abstract: A reordering tool for sequentially reordering data values assigned to graphical objects in a CAD model is described. The reordering tool can be a software application or a tool included in a software application. The reordering tool can have one or more graphical user interfaces configured to receive input from a user and present information to a user prior to reordering data values of the objects.
