RVM Page

Use this page to adjust the options for the RVM file reader.

Faceting Factor

Enter the required value to control the level of faceting that takes place.

The faceting factor must be greater or equal to 0, where 0 results in the faceting factor being turned off. The default value is 1. When you double the value, you get twice the number of facets. When you halve the value you get half as many facets. Larger faceting factors result in more polygons to a model and larger Navisworks files.

This setting controls the greatest distance between the edge of a facet and the actual geometry.

If this distance is greater than the Max Facet Deviation value, Navisworks adds more facets.

If the Max Facet Deviation is set to 0, then this function is ignored.

Convert Attributes

Select this checkbox to convert attribute files. All files located by the file reader are considered in the same order they were found. Attributes are matched to elements in the scene by name. Any attributes that were not found are counted, and the number reported in the scene statistics.

When this checkbox is clear, the file reader ignores attribute files.

Default Attribute Encoding

This setting controls the default encoding used for attribute files. Use the drop-down list to choose between UTF-8 or System locale.

Search All Attribute Files

Controls the way the file reader locates attribute files. The file extensions are specified in the Attribute File Extensions box.

When this checkbox is clear (the default option), the file reader checks the directory where the RVM file is located for an attribute file with the same name. If it cannot find an attribute file, then it looks in a subdirectory with the same name as the RVM file for all files with the specified file extensions.

When this checkbox is selected, the file reader first uses the default search method. If it cannot find any attribute files, it returns to the directory where the RVM reader is located, and looks for all files with the specified file extensions.

Attribute File Extensions

Specifies the file extensions that the file reader uses to recognize attribute files. The default extensions are *.ATT, *.ATTRIB, and *.TXT. Separate the values in the list with semi-colons.

Generate Texture Coordinates

Select this checkbox to create texture coordinates for each point in the model.

When this checkbox is clear, the file reader ignores texture coordinates.

Keep Empty Groups

Select this checkbox to convert groups that do not contain any geometry. Use this option when, for example, these groups contain attributes.

When this checkbox is clear, the file reader ignores empty groups. This is the default option.

Load RVS File

Select this checkbox to read an RVS file at the same time as the corresponding RVM file. This is the default option.

Note: To work correctly, the RVS file must have the same name, and path as the associated RVM file, but with an .rvs extension.

When this checkbox is clear, the file reader ignores RVS files.

RVS Transparencies as Materials

Select this checkbox to attach transparent materials to the objects. Use this option, for example, when large objects in the scene are permanently transparent, and you want to convert them as such.

When this checkbox is clear (the default option), the file reader ignores RVS transparency settings. Use this option, for example, when you want to override transparency settings in the RVS file.

Note: You can also override object transparency directly in Navisworks. (Click Item Tools tab > Appearance panel > Transparency slider.)

Convert Origins

Select this checkbox to convert component origin points into Navisworks snap points.

When this checkbox is clear, origin points are discarded.

Convert Zero-Thickness Solids

Select this checkbox to convert 3D solids with a zero thickness into 2D geometry.

When this checkbox is clear, 3D solids with a zero thickness are discarded.

Convert Lines

Select this checkbox to convert lines, such as pipe centrelines, steelwork locations lines, and HVAC lines. This ensures that the lines are rendered in Navisworks.

When this checkbox is clear, conversion of any geometry classed as a line is skipped, and so won't be rendered in Navisworks.

Convert Insulation

This setting controls the rendering of insulation geometry. Use the drop-down list to select from the following options:

Hide - Insulation geometry is hidden in the scene and appears in the Selection Tree as hidden (in grey). You can unhide the insulation geometry and make it visible in the scene by pressing Ctrl + H, or right-clicking in the Selection Tree and choosing Unhide.
Show - Insulation geometry is rendered in the scene and appears in the Selection Tree.
Skip - Insulation geometry is hidden in the scene and does not appear in the Selection Tree.

Convert Obstruction Volumes

This setting controls the rendering of obstruction volumes. Use the drop-down list to select from the following options:

Hide - Obstruction volumes are hidden in the scene and appear in the Selection Tree as hidden (in grey). You can unhide the obstruction volumes and make them visible in the scene by pressing Ctrl + H, or right-clicking in the Selection Tree and choosing Unhide.
Show - Obstruction volumes are rendered in the scene and appear in the Selection Tree.
Skip - Obstruction volumes are hidden in the scene and do not appear in the Selection Tree.

Enable Hyperlinks

Select this checkbox to convert AVEVA attribute values to hyperlinks. The default value is checked.

Hyperlink Definitions

This textbox accepts a semicolon-separated string of AVEVA attribute names that convert to hyperlinks. The default value is an empty string.

Example: :APCM_VIEWER; :APCM; :UDA_HYPERLINK
