Reference Attachment Settings dialog box

Used to attach a model to the active model. Opens when the reference to be attached is selected in the Attach Reference dialog box.

File Name

Shows the reference's name.

Full Path

Shows the full file specification for the reference, including the directory.

Model

Lists the models within the reference. Used to select the model to be attached to the master model.

Logical Name

Sets the logical name of the model.

Description

Sets the optional description for the model. The maximum valid description is 40 characters.

Orientation

Sets the view of the model being attached. The list may also include saved views. You can select more than one orientation to attach.

• Coincident
— Aligns the references with regard to design plane coordinates only.

• Coincident World
— Aligns the references with the active model with regard to both Global Origin and design plane coordinates.

• Top, Right, Front, Isometric, Bottom, Back, Left, Right Isometric
— Sets the views used to attach the reference. If the file being attached is 2D, you can choose only the Top view.

Scale (Master:Ref)

Sets the ratio of the master units in the active model to the master units in the attached model.

Level

(DWG workmode only) Sets the level for the reference to be attached.

In an AutoCAD DWG or DXF file, each XREF or layout viewport is placed on a specific layer. When you open the DWG file in MicroStation, XREFs and layout viewports are treated as references, and are placed on the same level (layer). To modify a reference's level, open the References dialog box, double-click on the reference to open the Attachment Settings dialog box, and modify the Level setting.

If a level is frozen, references on that level are not displayed.

True Scale

If on, units in the active model align one to one with units in the referenced model. For example, if the units in the active model are inches and the units in the referenced model are meters, meters are converted to inches so the elements are referenced in at the same relative size.

Nested Attachments

Determines if referenced models attached to reference models (and, so on) are recognized when a model is attached to the active model.

• No Nesting
— Models attached to the attached model are not recognized in the active model.

• Live Nesting
— If on, the hierarchical structure of any nested references are maintained when attaching the parent reference to a model. When you attach a reference that has one or more attachments, and if you set the Nest Depth high enough, all of the nested attachments display in the view window; however you see only the parent reference in the References dialog box's list box. To see the hierarchy of any nested references, use the Show Hierarchy icon on the References dialog box..

• Copy Attachments
— Models attached to the attached model copied directly into the active model, disregarding the hierarchical structure of the nested references. When you attach a reference that has one or more attachments, and if you set the Nest Depth high enough, all of the attachments are displayed in the view window, and all of the attachments (parent and any nested references) are listed in the References dialog box's list box as individual attachments.

When working in a DWG or DXF file, live nesting is always on, and there is no limit to nest depth. Therefore the Nested Attachments and Depth items are disabled. To control the display of nested attachments, use the Ignore Attachment When Live Nesting setting (on the Attachment Settings dialog box).

The Live Nesting option merely allows nested references to be attached hierarchically when the parent reference is attached to the model. In MicroStation, a nested attachment is displayed only if the child reference does not have its Ignore Attachment When Live Nesting setting turned on, and the parent reference has Live Nesting enabled.

Once you attach a nested reference, you can “flatten” it to a direct attachment. To do this, change by changing its Nested Attachments setting in the Attachment Settings dialog box or by right-clicking its entry in the References dialog box and choosing Make Direct Attachment. The latter technique makes the nested attachment becomes redundant with the newly created direct attachment.

The No Nesting, Live Nesting, and Copy Attachments options can also be set as the Default Nesting preference in the Reference category of the Preferences dialog box.

Depth

Sets the number of levels of referenced models that are recognized. Models can have their own referenced models, which, in turn, can have more referenced models, and so on.

If Depth is set to 0, only the model is attached to the master model; referenced models in the referenced model are ignored.

When working in a DWG or DXF file, live nesting is always on, and there is no limit to nest depth. Therefore the Nested Attachments and Depth items are disabled. To control the display of nested attachments, use the Ignore Attachment When Live Nesting setting (on the Attachment Settings dialog box).

Display Raster References

If on, raster references will display in the master model.

OK

Attaches the model and closes the dialog box.

Cancel

Closes the dialog box without attaching a model.

Options…

Opens the Attachment Settings dialog box, which is used to adjust the settings of a referenced model.

The settings are:

• Display — Turns the view of a reference on or off.

• Snap — If on, allows you to snap to elements in a particular reference, when the reference is attached.

• Locate — Controls whether elements in a reference can be identified.

• Clip Back — Sets the back clipping plane for a 3D referenced model.

• Clip Front — Sets the front clipping plane for a 3D referenced model.

• Scale Line Styles — If on, custom line style components (for example dashes) are scaled by the Scale factors. If off, custom line style components are not scaled.

• Ignore Attachment When Live Nesting — If on, this ensures that if the current attachment becomes a nested reference, it will be ignored.

• Use Lights — If on, during processing for rendering, the source lighting cells present in the active file always are considered. Any source lighting cells located in references are ignored unless the Use Lights setting is turned on for the reference.
