"Computer Aided Design software is well-known, and used by architects, engineers, designers, planners, construction firms, and owner operators and the like to create and use precision models and technical illustrations. The software is used to create design simulations that are two-dimensional (2-D) drawings, and three-dimensional (3-D) models and related tabular and business property data. Applications such as, e.g., MicroStation.RTM.. products, including design applications spanning many infrastructure disciplines, and general purpose review applications such as (Navigator.RTM.) and construction applications such as ConstructSIM.RTM.. which are developed by
"Three-dimensional (3D) assets are commonly designed, analyzed, and built, using a process in which design teams invest large amounts of time, money, and effort, creating insightful 3D digital models of those assets using design software. Design teams gain a tremendous amount of insight into projects while constructing and editing these 3D models. These 3D models are used commonly for analytical and visualization purposes, and increasingly, models are used to automate the production of conventional construction drawings.
"Conventional construction drawings are 2D, flat abstractions of things. Conventional construction documentation drawings assist design professionals in explicitly defining limits of liability of the design professionals who draw them. Project designers mitigate liability a priori by selecting the locations within a project at which they intend to design, draw (automated by 3D models or not), and be held accountable.
"The locations that the designers select are the locations that they draw. The selection of these locations is designated with graphical callout symbols ('callouts'). Callouts are an a priori statement of intent. These callouts are placed on various drawings, typically starting with plan drawings.
"Assuming that designers abide by their professional standards of care by selecting enough locations to draw, and that these locations are sufficiently representative of the diversity of designed construction details of a project, design professionals are held accountable for the drawings that they draw, not for the ones they don't draw and that therefore do not appear on construction drawings.
"Conventional construction drawings, whether their production is automated from 3D models or not, have remained essentially innovation-less for hundreds of years. Conventional drawings leave much of the insight gained during the creation of the 3D digital models behind.
"Design teams that invest energy; time, effort, and money into the creation of 3D digital models desire to transfer more or all of the insight they gain while building those 3D models, to the design collaborators on their team while they work, and into the next phase of work--delivery for construction, and beyond, into asset operation, maintenance, management.
"Design teams desire to provide as much useful information from their design processes as possible. The insight developed during the design of 3D models should be delivered downstream to users, like contractors, subcontractors, owners, and operators. Therefore, delivery of the 3D models, on which considerable effort has been expended, and which contain essential project insight, is desired.
"However, certain factors prevent the delivery of 3D models and make such delivery, practically speaking, unachievable. A 3D model represents the full scope of a project, a whole thing, rather than a limited pre-selected set of locations within a project that are drawn. This whole 3D model may be incomplete. As much as any design team may wish to try, the 3D model may never be 100% complete throughout every cubic millimeter of the project; and far from it, in fact. 3D models are a mixture of locations that are complete and locations that may be, and may remain, incomplete. 3D models, delivered as they are today in the industry, 'naked' so to speak, are completely ambiguous. No one can distinguish between the locations in 3D models that are complete and the locations that are not complete. Models are frequently discarded because of that ambiguity. No one can tell which locations in the model are complete and which locations are not complete, nor can anyone tell who claims responsibility for any particular location in a model. 3D models are an unreliable medium with which to communicate design and construction intent, as 3D models omit any device that provides clarity with regard to location-specific authorship and location-specific completeness, precisely those things that design professionals require in order to be clear and in order to mitigate risk in their professional practice. It is this deficiency of 3D models that is addressed by this invention and solved."
As a supplement to the background information on this patent application, VerticalNews correspondents also obtained the inventors' summary information for this patent application: "In an exemplary embodiment a computer useable information storage medium storing computer readable program code means for causing a computer to perform the steps of: creating a 3D artifact representing an object: creating a 2D artifact defining design details of a location in the object; creating an assemblage of the 2D and 3D artifacts where the 2D artifact is linked to the location in the 3D artifact; providing an interface node in the 3D artifact at the location indicating a 2D artifact is provided; dynamically displaying the 2D artifact at the location in the 3D artifact when the interface node is selected.
