But there have always been challenges involved in trying to describe a 3D world in a 2D drawing. It is very difficult to unambiguously describe a complex 3D part in a series of 2D drawings. Misunderstandings were common and these often resulted in costly delays and sometimes in the construction of bad parts. Many 2D drawings were often required to describe a single 3D part or assembly. When design changes were made, a difficult and error-prone process was required which often involved correcting many drawings. The advent first of 3D computer aided design (CAD) and later of solid modeling provided a major advance. Solid modeling provides the ability to unambiguously define 3D geometries in a single geometrical file. Furthermore, the solid model provides the ability to verify the form, fit and functionality of the product prior to construction of prototypes.
But 2D drawings have continued to play an important role in the design process by providing tolerancing, annotations, parts lists and other information that is critical to downstream processes, such as manufacturing, quality control, and the supply chain. Without the third dimension, all of the planes and features in any view are all on top of each other even if they are at the ends of the part. So it is extremely difficult to create 2D sections that accurately and completely show the key features and surfaces that tolerances and annotations are applied to. This often leads to errors because downstream users cannot identify exact part features when looking at a 2D drawing of a complex part.
One more concern is that when inevitable design changes occur, three different datasets - the solid model, 2D drawings and parts lists - usually need to be updated. It is possible for any of these datasets to get out of sync with the others, requiring additional time to maintain them. This often results in delays for design changes or making the incorrect parts.
Picture 4: Product development with 3D Master concept
The latest generation of solid modeling systems makes it possible to insert the dimensions, geometry design and tolerancing, annotations and parts lists directly into the solid model, eliminating the need for drawings. Any number of views of the 3D model can be composed, detailed and annotated or specific downstream groups such as manufacturing planning, product services, procurement and marketing /sales. For example, a live 3D model with a prescribed series of annotated and dimensioned views can be provided to a contract manufacturer 2D layout for 3D design capabilities enables users to work in a 3D environment with advanced 2D drafting capabilities during the conceptual phase of a project. 2D geometry can be exported as profiles and planes for fast and easy 3D geometry creation. Dimensioning and tolerancing annotation data can be added during the preliminary phase, eliminating the need for it to be recreated in a downstream process.

Virtual teams and communities can meet in a real-time environment to search, navigate, chat and collaborate on any aspect of a product related program. The environment improves decision-making by providing early and direct insight into dimensioning and tolerancing annotations, geometrical elements and features, and the relationships between elements.
Working with a 3D model, the engineer can be absolutely certain that he or she is applying the tolerance to the desired feature and anyone using this information can be sure they are producing or measuring the correct feature. Confusion over different 2D drawing standards is eliminated because 3D is universal and looks the same to everyone everywhere. The 3D Master approach also provides considerable savings in the reuse of product definition information in product families or future versions of the product.
Product Lifecycle Management (PLM) systems greatly enhance the ability to reuse geometric information. The 3D Master approach makes it just as easy to reuse the complete product definition, including tolerance and annotations and parts lists. Advanced users can create templates containing tolerancing and annotations and parts lists that make it possible to automate new areas of the product development process. Another advantage of incorporating tolerancing into the solid model is that it opens the door to reducing manufacturing costs by opening up unnecessarily tight tolerances. Incorporating the tolerances in a 3D Master model makes it much easier to use tolerance analysis tools that predict the assembly variations based on the tolerancing specified for individual parts while taking both deformation and the assembly process into account. Simulating the build variation determines if the product and process, as designed, meets the dimensional product requirements and determines the impact of individual tolerances on the assembly variation. This type of simulation often makes it possible to loosen tolerances, resulting in manufacturing cost reductions of up to 90%.
Picture 6: Drive accuracy into your business
Despite the broad adoption of 3D modeling, the 2D drawing remains the primary reference for dimensions, tolerances, and annotations for 90% of manufacturing companies. The central concept of the 3D Master approach is that the 3D product model is the most appropriate vehicle for delivering the detailed product information needed by downstream processes.
