Utilizing Start Parts for MBD

You define template MBD combined states in the start part.

  • Benefits

  • Standard MBD Notes

  • States

  • Schema options

The benefits of using a —start part — template for MBD include time savings and standardization as the combined states are pre-created as placeholders. Many notes and other information are reused for each model.

The required MBD states can be included in the start part. The following states are created in the class files example:

  • 1_Map is completed once the part has been annotated. May be done first to define item 7A, 7B, 7C, and so on.

  • Typically a few notes with leaders defining the different combination states.

  • 2_General Nothing to add.

  • Most items driven by parameters.

  • 3_Properties Add envelope dimensions.

  • Most items driven by parameters.

  • 4_Notes Include standard company notes.

  • Add model-specific notes.

  • 5_Datums Add GD&T datums.

  • 7A, 7B, 7C, and so on. Customized for the part annotations.

  • Combined states with GD&T callouts.

Schema notation for an MBD start part can be verbose, minimal, or numeric only, as shown in the following examples:

  • Verbose — Mbd0_Default

  • Minimal — D0_Default

  • Numeric — 0_Default

Steps

  • Task 1. Access combined states and Annotate mode in the start part. Enable only the following Datum Display types: Figure Figure Notice the empty model.

Figure

  • Click View Manager Figure from the In Graphics toolbar. Select the All tab.

  • Notice the list of combined states already defined for this start part model.

Figure

  • Click Close .

  • In the ribbon, select the Annotate tab. Notice the detail tree and model tree contents.

Figure

  • Task 2. Review annotations belonging to combined states. Select the Model_Only combined state tab. Notice only the empty model is shown.

Figure

  • Select the 1_Map combined state tab. Notice the default leaders, which would later be relocated to model geometry.

Figure

  • Select the 2_General combined state tab. Notice the company information.

Figure

  • Select the 3_Properties combined state tab. Notice the template parameter information.

Figure

  • Select the 4_Notes combined state tab. Notice the default notes, which can be edited.

Figure

  • Select the following combined state tabs and notice these combined states are initially empty: 5_Datums
