A 3D modeling allows easing of navigation and design by outsourcing visualization tasks to the computer to save cognitive resources of personnel which in its terms provides higher precision and accuracy of labor. Usage of 3D models during service and maintenance is more beneficial than its usage during design. When a product is in the design stage, and there is no tangible object, an error which needs to be fixed won’t create life-threatening conditions for a person who is fixing it; however, when an error occurs during the maintenance or service, the consequences may be devastating.
Keel has created a small but elegant 3D-models library with the purpose of integration into product lifecycle management software. The creation of 3D models ironically consists of 3 main stages: input gathering, analysis, modeling and adjustment.
The input gathering is all about the obtaining all available information, which may be helpful for the modeling of a product. Usually, this information is needed about the physical parameters of the product and its subparts: dimensions, materials, and mechanical relations with other parts.
The second stage is where the level of detail is determined based on the purpose of the model usage, for example, when an existing object needs a model for service, the level of details should be reduced to the smallest spare part, excluding some bolts and parts that aren’t serviceable according to the existing procedures.
The final stage is modeling, which is what it is – a transformation of a set of data into a single mathematical representation of a physical object via software.
When the modeling is finished, the output can be used for multiple purposes:
