Downloaded from https://www.everyspec.com MIL-STD-31000A 5.2.3 Limited design disclosure models: When a 3D TDP is required and a subcomponent to the end item does not require complete design disclosure, (such as a commercial item, purchased item, etc.), a 3D digital model of the subcomponent shall be provided. The subcomponent’s 3D digital model need not be fully defined, but shall be sufficient to provide adequate visualization, interface characteristics, accurate weight and center of gravity information as required (i.e. cosmetic model) (see para 3.1.21). 5.2.4 Model Organization Schema:
When a 3D TDP is provided in accordance with 5.3.2.2, then all annotations and views contained within the model shall be done in accordance with a Model Organization Schema that is compliant with or can be mapped to the one defined in Appendix B of this document. If a different Model Organization Schema is used, a document defining the mapping of the elements of that schema to the one referenced in Appendix B should be required. 5.3 TDP levels, types, elements and associated data. TDPs shall consist of one or more of the following TDP levels, types and elements as specified in the contract or purchase order and TDP Option Selection Worksheet. 5.3.1 TDP Levels. 5.3.1.1 Conceptual level.
- A conceptual design TDP shall consist of those TDP elements necessary to define design concepts in graphic form, and include appropriate textual information required for analysis and evaluation of those concepts. The data will generally consist of simple sketches/models, artist renderings and/or basic textual data. The data may consist of the system performance specification (see 5.3.3.7) and can be supported by Conceptual design drawings and/or models (see 5.3.3.1) as specified by the contract. 5.3.1.2 Developmental level.
- A developmental prototype TDP shall consist of those TDP elements necessary to provide sufficient data to support the analysis of a specific design approach, the fabrication of prototype materiel for test or experimentation, and limited production by the original design organization or with assistance from the original design organization. The data may consist of the unique item specifications (see 5.3.3.7). for all system component Configuration Items (CIs) and can be supported by developmental design drawings and/or models along with any required associated lists (see 5.3.3.2) as specified by the contract. 5.3.1.3 Production level.
- A production level TDP shall consist of those TDP elements necessary to provide the design, engineering, manufacturing, inspection, packaging and quality assurance provisions information necessary to enable the procurement or manufacture of an item. The product shall be defined to the extent necessary for a competent manufacturer to produce an item, which duplicates the physical, interface, and functional characteristics of the original product, without additional design engineering effort or recourse to the current design activity. Production data shall reflect the approved, tested, and accepted configuration of the defined delivered item.
The data may consist of product drawings and/or models along with all required associated lists (see 5.3.3.3); SIE drawings and/or models along with all required associated lists (see 5.3.3.5); ST drawings and/or models along with all required associated lists (see 5.3.3.6); specifications (see 5.3.3.7); software documentation (see 5.3.3.8); SPI drawings and/or models along with all required associated lists (see 5.3.3.9); and QAP(see 5.3.3.10) as specified by the contract. 5.3.2 TDP types. TDP Type describes the form and format of the data as imposed by the 14
