Loading reference filters

The MS_LEVEL_LOAD_ATTACHMENT_FILTERS configuration variable, if set, loads level filters of reference attachments when the master file is opened. For every unique attachment by file, a top-level filter is created. This top-level filter represents the reference attachment. All filters of the reference attachment are loaded as children of this new top-level filter. The reference filters may be modified in the context of the current session. These changes are not persisted in the DGN file and are discarded when the session is terminated.

To activate the loading of reference filters

From the Workspace menu, choose Configuration.
The Configuration dialog box opens.

In the Category list box, select Levels.

In the Modify levels related configuration variables list box, select Load Attachment Level Filters.

Click Edit.
The Edit Configuration Variable dialog box opens.

Key in 1 in the New Value field and click OK.
The Edit Configuration Variable closes.

Click OK.

Click Yes to save the change to the configuration file.

Copy and Paste levels within the open file and reference attachments

There are several ways to copy levels and level attributes within the open file and attached references.

Open file to open file copy
Open file to reference copy
Reference to reference copy
Reference to open file copy

Open file to open file copy

You can copy a level and all its attributes in the open file, then rename it to create a new level with the same attributes.

To create a copy of a level in the open file

Select the open file from the tree.

Select the level(s) to be copied.

Right-click in the level list.
A pop-up menu opens.

Select Copy from the menu.

Select Paste from the menu.
A copy of the selected level(s) appears in the level list.

Select the copy of the level.

Right-click in the level list.
A pop-up menu opens.

Select Rename from the menu.
The level name takes the focus as an input field.

Type in the new name of the level and press <Enter> to accept the name.

Open file to reference copy

You can copy a level's attributes in the open file to a level of the same name in an attached reference. These attribute changes in the attached reference are for view or plotting purposes but do not change the actual levels in the source file since references are view only. For example, if Level 1 is green in the open file and blue in the attached reference, you can copy the attributes from the open file to any selected reference attachment that contains that level.

To copy level attributes from the open file to attached references

Select a level from level list of the open file.

Right-click in the level list.
A pop-up menu opens.

Select Copy from the menu.

Select a reference attachment(s) from the tree.

Right-click in the level list.
A pop-up menu opens.

Select Paste from the menu.
The attributes in the reference attachment(s) are copied to match the level in the open file.

Reference to reference copy

You can copy a level's attributes in a reference to a level of the same name in another attached reference(s). These attribute changes in the attached reference are for view or plotting purposes but do not change the actual levels in the source file since references are view only. For example, if Level 1 is green in the selected reference and blue in the another attached reference(s), you can copy the attributes from the selected references to any other reference attachment(s) that contains that level.

To copy level attributes from attached reference to attached reference

Select a reference attachment in the tree.

Select a level from level list of the selected reference attachment.

Right-click in the level list.
A pop-up menu opens.

Select Copy from the menu.

Select a different reference attachment(s) from the tree.

Right-click in the level list.
A pop-up menu opens.

Select Paste from the menu.
The attributes in the reference attachment(s) are copied over with the attributes of the level in the originally selected reference attachment.

Reference to open file copy

You can copy a level's attributes in a reference to a level of the same name in the open file. For example, if Level 1 is green in the selected reference and blue in the open file, you can copy the color attribute from the selected references to the open file. This copy changes the attributes of the level in the open file.

To copy level attributes from attached reference to the open file

Select a reference attachment in the tree.

Select a level from level list of the selected reference attachment.

Right-click in the level list.
A pop-up menu opens.

Select Copy from the menu.

Select the open file from the tree.

Right-click in the level list.
A pop-up menu opens.

Select Paste from the menu.
The attributes in the reference attachment(s) are copied over the attributes of the level in the open file.

Miscellaneous Level Key-ins

To renumber one or more levels via key-in

Key in LEVEL RENUMBER increment—value level-spec.
The level-number of all levels specified by the 'level-spec” are incremented by the “increment value”. The increment can be positive or negative.

To report non-standard levels via key-in

Key in LEVEL REPORT NONSTANDARD report-file–name.
All levels of the master-file are checked against levels in a level library. Non-standard levels – i.e., level that exist in the master-file but not in the level library are reported. Library levels in the master-file but with non-standard attributes are also reported. The report is output in file “report-file-name”. If the report-file-name is not specified, then the output is sent to the Bentley Text Window. This function is a simple alternative to the Standards´ Checker and can be used to quickly find non-standard levels in a single file.
