Property Editor

The extents grid displays the size of a bounding box containing the model (3D), and if the selected document is a sheet metal part with a generated flat pattern, the size of a rectangle containing the flat pattern top face, and the sheet thickness. If the current iPropWiz configuration specifies that model or flat pattern extents be exported as custom iProperties, the values will use any custom formatting rules applied to the exported values.

The values can only be displayed when a single part or assembly is selected for edit.

The values are not initially displayed when the selection changes. Click the refresh button to the right of the grid to update the values.

The values are displayed using the active formatting rules for model and flat pattern extents (if available).

Model extents

The extents of the active part, assembly, or folded sheet metal part are displayed here. In an iPropWiz configuration, you can chose to export part model extents using one of three methods. Examples of the different export options are shown in the following images. Assembly extents are always calculated in the assembly XYZ coordinates, and flat pattern extents are always in the flat pattern XY coordinates.

Models extents calculations for the part shown in the following image are shown in the following table. The part is not aligned to the coordinate system and an iPropWiz UCS named IPW is attached to a corner of the part. Formatting for exported extents is fractional inches for values < 10 feet, and feet and inches for values >= 10 feet. See the Configuration Editor - Options - Model Properties page for more information on setting up the export of model extents.

Part X, Y, Z (Default)		The part model extents are reported in the part's XYZ coordinate system.
Named UCS		The part model extents are reported relative to a specified UCS. The icon in the Extents title bar indicate a UCS is used for the extents, and the name of the UCS feature is shown in brackets in the Model cell. See the UCS Setup for Part Model Extents section below for information on managing extents relative to a part UCS.
Principal Axes		The part model extents are reported relative to the Principal Axes of the part. The icon in the Extents title bar indicates the extents are relative to these axes. This option may give better results for relatively symmetrical parts that are created in-place in an assembly (i.e. frame components, derived component work flows). In this example, these extents closely match the actual size of the part.
Minimum Bounding Box ( Inventor 2021+ only )		The part model extents are reported as the smallest bounding box that can fully encloses all visible solid bodies in the part document. If you are using Autodesk Inventor 2021 this is the preferred option for parts that are created in top down design scenarios and may not be aligned to the part coordinate system. The extents are exported with unique custom property names not associated with the part coordinate axes. ( ipwModelExtentsDir1, ipwModelExtentsDir2, and ipwModelExtentsDir3 ).

Note: (New: Oct 2023 - V7.23+) Model and flat extents for individual model state documents are now supported. A configuration setting controls whether updates to the extents occur only for selected model states or all model states when property values changes are applied or the document is saved. See the Configuration Editor - Options - Model States page for more details.

Flat pattern extents

If the active Autodesk Inventor document is a sheet metal part, and the part includes a flat pattern, the flat pattern extents ( X and Y ) are displayed here.

Dec 2020 : Flat pattern thickness is now shown in the third column of information. If a formatting rule is included in the current iPropWiz configuration, the formatted value is displayed.

UCS Setup for Part Model Extents

If the active configuration specifies that the part model extents are to be reported relative to a named UCS, you must add a UCS feature in the desired orientation, and then convert the UCS into one that is tracked by iPropWiz.

In each part where you want the extents aligned to a named UCS:

1.In the part model, create a UCS and align it to meet your requirements for reporting model extents.

2.Right-click the UCS (in the graphics window or browser) and click Create iPropWiz UCS.

The UCS is renamed to match the name specified in the iPropWiz configuration.

In addition, the UCS can no longer be renamed, and visibility of the UCS subcomponents is controlled by the iPropWiz application.

Note: If the UCS requires changes, you can use the Redefine command from the UCS context menu. You can also delete a UCS that has been converted to an iPropWiz UCS.
