Downloaded from https://www.everyspec.com MIL-STD-31000A APPENDIX B B.7.4 Combination Views. Combination Views are used for defining an associative relationship between digital elements to comply with ASME Y14.41 section 5.2.1. A combination view allows one to combine and apply multiple View states and Logical Groups. Multiple combination views may be saved to display all the required product definition data. Figure 10 shows a typical list of combination views. Combination views allow one to quickly navigate customized model display states to display required information by combing multiple View states. Combination views should be used to manage the following data:
View States (orientation, x-sections, styles, simplified representations and explode states) Logical Group Status Annotations (dimensions, GD&T, notes, text or symbols) The naming convention should be MBD#_Description, items which have numerous such as MBD7 should have the numeric followed by an alpha character and description such as MBD7C_Front_Pocket. Figure 10. Combination Views. The following is a list of suggested Combined States: State Name Description of Contents Displayed 0_Model_Only Although it is not required for MBD this view is recommended to quickly hide all annotation displaying only the model specific notices. NOTE :
File to be saved in this state MBD0_Default Legal notice, Proprietary notice, ITAR notice and/or other company MBD1_Site_Map Notes identifying all available combination views – 3D roadmap MBD2_Titles Title Block information (Company name, design description, model number, cage code, design signatures, block tolerances, material and finish requirements) MBD3_Properties Overall boundary dimensions, mass properties, material, finish requirements and title block information MBD3_Characteristics Optional – Key characteristics MBD4_Notes General note information MBD5_Set_Datums Set datums MBD6_User_Derfined Exploded Views and Assembly Unique views MBD7_User_Defined Define the details of the Machining operations using annotations MBD8_User_Defined Define the details of the Welding operations using annotations 43
