Save As V7 Options Dialog, References Tab

Controls how references are handled when you save a file as a V7 DGN file.

You can choose to keep references as attachments, combine a file and its references into a single output file, or omit the reference attachments from the output file.

Save As V7 Options, References tab

Setting	Description
Levels from View	Identifies which levels from the reference attachments are merged (if a merge option is selected for the attachments). View1 — View 8 — Elements are merged only if they are from levels that are displayed in the selected view.
External Attachments	Controls how standard attachments to the default model are handled when you save to a V7 file. Retain — Keeps the attachments to the output file. Merge — Merges the attachment geometry into the output file as individual elements. Merge to Cell — Merges the attachment geometry into the output file as a single cell. Omit — Does not save the attachment to the output file.
Self Attachments	Controls how self-attachments are handled when you save to a V7 file. A self-attachment is a reference attached to itself. In the product, self-attachments are often used to create detailed sections of a drawing. Retain — Keeps the attachments to the output file. Merge — Merges the attachment geometry into the output file as individual elements. Merge to Cell — Merges the attachment geometry into the output file as a single cell. Omit — Does not save the attachment to the output file.
Non-Default Models Attachments	Controls how attachments to non-default models are handled when you save to a V7 DGN file. V7 files contain a single model. Therefore, when a V8 file is saved to a V7 file, only the default model is saved. Any additional (non-default) models are saved to separate files with the model name appended to the output file name. For example, if the V8 file Test.dgn has two sheet models, "Sheet1" and "Sheet2," and you choose to save the file as v7test.dgn, the result will be three V7 files: v7test.dgn, which contains the default model v7test_sheet1.dgn v7test_sheet2.dgn. The reference attachments to non-default models will be updated to attach to the appropriate V7 files. Retain — Keeps the attachments to the output file. Merge — Merges the attachment geometry into the output file as individual elements. Merge to Cell — Merges the attachment geometry into the output file as a single cell. Omit — Does not save the attachment to the output file.
Live Nested References	Controls how live nested references are saved to V7 files. V7 does not support live nesting. Omit — Does not save live nested references to the output file. Copy to Master — Saves live nested references to the output file, along with the appropriate clipping boundaries, level display, and other settings to preserve each reference's appearance.
Merge Visible Edges of 3D Attachments	If on, a 3D reference file attachment will have its visible edge representation merged into the master file. This setting affects all references except the ones that display wireframe geometry. This option is useful when using Dynamic Views because target formats such as DWG and V7 DGN do not support the dynamic view display options. To check the effect of this setting refer to the example in Merging References into the Active Model. If on, this setting overrides all attachment settings above it. When you turn on this check box, an Visible Edges Settings icon appears next to it. Clicking this icon opens the Visible Edges Settings dialog.
Copy Levels During Merge	Describes how levels are handled when you merge references from the DGN file into a DWG/DXF file. If Not Found — Levels from the reference are merged into the output file only if they (or a level with the same name) do not exist in the active model. If Overrides Exist — Levels from the reference are merged into the output file if the level does not exist in the active model, or if the settings for the active model level are different than those of the attachment. Differences include overrides that have been applied to the attachment levels, or differences between the levels as defined in the active model and reference. Always — Levels from the reference are merged into the output file even if an identical level exists within the active model.
Convert Reference Files	If on, when saving a DWG or V8 DGN file to a V7 DGN file, all references are converted to V7 DGN files. When saving a V7 DGN file to another V7 DGN file, because the file format for the master file is not converted, the file formats for references are not converted. However, the references are re-saved. If the master file is saved to a different directory, all references are also saved to that directory. If the master file is saved to the same directory, then each reference is saved to its original directory.
Allow Optimized Clip for Reference Merge	If on, maintains the surfaces and solids and shapes when they are clipped during the merge process. If off, the surfaces and solids are dropped to their boundary/wireframe elements.
Merge Displayed Levels Only	If on, levels displayed in the selected view are merged into the output file. If off, all levels are merged into the output file. Note: This setting is turned on and disabled if the configuration variable MS_MERGE_DISPLAYEDLEVELSONLY is set.
