MIL-STD-31000 AND 3Dipdf TDP UPDATEJeff WindhamUS Army [email protected]
THE HISTORYTHE EVOLUTIONTHE PURPOSETHE GRADETHE GOALTHE STATUS2
What is a Technical Data Package (TDP)?Defined by MIL-STD-31000The authoritative technical description of an item supports the acquisition, production, inspection,engineering, and logistics defines the required design configuration 3
Common Myth: The TDP exists for purposes of manufacturing theitem. Fact: The TDP exist for purposes of defining the item. It is an engineering document, not a manufacturing document. As the single authoritative engineering definition of the item, it hasmany uses: ManufacturingInspection/Quality ControlLogistics SupportEngineering AnalysisConfiguration Mgt.Interface Mgt.4

DESIGN IT. BUILD IT. SUPPORT IT.
Why Model Based Enterprise?The Model Based Enterprise lets us design it, buildit and support it –faster, better and cheaper.

Model Based EnterpriseConsist of several sub-elements (MBx) MBSE: System Engineering MBT&E: Testing & Evaluation MBI: Inspection/QA MBM: Manufacturing MBS: Sustainment (Operation, Maintenance &Logistics) MBDes/EA: Design, Engineering Analysis MBDef: Model Based Definition
THE PURPOSE:MODEL BASED ENTERPRISE Build organizations around the 3D model Have a seamless flow of information thru the organization Grow the use of models (of all types) across theorganization Improve models in the MBx areas Stop recreating information, over and over and overagain.10
THE GRADE: Improving models in the MBx areas? Grade: A Building organizations around the 3D model? Grade: B Stop recreating information over and over? Grade: C Having a seamless flow of information thru the org.?Grade: D Grow the use of models across the org? Grade:Incomplete11
HOW DO WE “RAISE THE FLOOR”: Hugh variation in MBE implementation across DODprograms. Many programs/organizations doing phenomenal MBEefforts. Others little or nothing. How do we “RAISE THE FLOOR”? The three primary tools to raise the floor: Standards, training, policy.12
UPDATE OF MIL-STD-31000 B RevTHE GOAL:Transform DOD to a modern technicaldata infrastructure based on 3Di pdfmodels.13
The TDP, as the authoritative definition of the item:Anything which allows for better communication of designintent is GOOD.Anything which detracts from communication of designintent is BAD.The 3Di pdf is a better way to communicate design intent.
In DOD, despite advances in 3D CAD, the TDP is stilllargely defined by black line art, third angle projection,“FRONT-TOP-SIDE” View, 2D engineering drawings.15
3Di PDF Example16
Why 3Di pdf TDPs? 3Di pdf provides better method to convey design intent overtraditional black line art, 3rd angle projection “front-top-side” 2Ddrawings. Can provide a complete, authoritative engineering definition. CAD agnostic. 3Di pdf does not require training (to use) and can be openedwithout special software. 3Di pdf is interactive, allowing user to select annotations withvisible surfaces and features highlighted. 3Di pdf utilizes feature based view states for more logicalpresentation of the design features. Future addition of STEP to the 3D pdf adds more capability. The technology is here today, all we need are the standards,business processes, and training to implement it.17

3Di TDP Implementation: What do we need to do? Standardize processes across DOD where it makessense. Implement the processes in real world programs. Grow the capability such that is standard business. Update of MIL-STD-31000 to allow for andencourage 3Di based TDPs.19
Update of MIL-STD-31000. Published as B Revision Oct 2018. Incorporates the concept of 3Di pdf models. Make other updates as needed. Removing Appendix B: Organizational Schema Standard for Model BaseDefinition (MBD) and Appendix C: 3D TDP Validation Guide. (this info movingto ASME Y14 series) Updating and clarifying the TDP Option Selection Worksheet. Adding TDP List (TDPL) as a TDP Data management product. Other misc. corrections and clarifications.20
MIL-STD-31000 A Rev to B Rev TDP types. Type 2D: 2-DimensionalTechnical Data Package. Type 3D: 3-DimensionalTechnical Data Package.Type 3D will include one ormore:1) 3D models only.2) 3D models with associated2D drawings. TDP types. Type 2D: 2-DimensionalTechnical Data Package. Type 3D: 3-DimensionalTechnical Data Package.Type 3D will include one ormore:1) 3D native models.2) 2D drawings derived fromthe 3D native models.3) 3Di pdf viewable dataderived from the 3D nativemodels.4) Neutral files derived fromthe 3D native models.21

Summary. DOD is moving to a modern Technical Datainfrastructure based on 3Di (3D Intelligent) models. 3Di model based TDPs are better than 2D, black lineart, third angle projection, “front-top-side”. Govt/Industry teams need to engage early andoften on best TDP solution for their programs. Get familiar with MIL-STD-31000B and use it onyour programs. Be advised, requirement to deliver 3Di pdf basedTDP may be coming soon to a contract near you.23
BACKUP SLIDES24
TDP Option Selection Worksheet Intended as the starting point for planning for TDP. Becomes a contractual document supporting the SOW. When ordering 3D TDP, the Option Selection Worksheetmust be supported by additional explanation,instruction, SOW verbiage, etc.25

Standardization on a NATIVE CAD software is adesirable, but unachievable goal.
3Di: Not your Grandfather’s TDP. PAST/PRESENT: TDPs based on 2D, black line art, third angleprojection, “front-top-side”, paper based. Didn’t matter how you got there, as long as you delivered the 2D drawing.2D drawing was universally understood.Form and format didn’t matter because everything could be rendered to paper.Human readable information. FUTURE: Much more complex. Data form and pedigree matters.Multiple formats being used likely.Programs will vary in how they operate.Both human and machine readable information.We need a common language.34
Summary 2D drawing based TDPs are the past. 3Di pdf based TDPs are the future. DOD organizations and our OEMs/suppliers need toestablish the ability to deliver and use 3Di basedTDPs. TrainingInfrastructureStandardsProcedures
The TDP is the single authoritative definition of theproduct. It is the culmination of the science, engineering anddesign efforts that came before it.,. and is source data for all mfg.,logistics, and acquisition activities which comes after it.TDP
DLA Study Defense Logistics Agency conducted a study ofusing 3Di pdf, in conjunction with STEP format. Procured parts from a variety of manufacturer’susing 3Di pdf technical data.37

Why 3Di pdf TDPs? 3Di pdf provides better method to convey design intent over traditional black line art, 3. rd. angle projection "front-top-side" 2D drawings. Can provide a complete, authoritative engineering definition. CAD agnostic. 3Di pdf does not require training (to use) and can be opened without special software.
