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 Autodesk Navisworks files. Max Facet Deviation 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, Autodesk Navisworks adds more facets. If the Max Facet Deviation is set to 0, then this function is ignored. Convert Attributes Select this check box 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 check box is clear, the file reader ignores attribute files. 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 check box 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 check box 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 check box to create texture coordinates for each point in the model. When this check box is clear, the file reader ignores texture coordinates. Keep Empty Groups Select this check box to convert groups that do not contain any geometry. Use this option when, for example, these groups contain attributes. When this check box is clear, the file reader ignores empty groups. This is the default option. Load RVS File Select this check box 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 check box is clear, the file reader ignores RVS files. RVS Transparencies as Materials Select this check box 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 check box 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 Autodesk Navisworks. Convert Origins Select this check box to convert component origin points into Autodesk Navisworks snap points. When this check box is clear, origin points are discarded. Convert Zero-Thickness Solids Select this check box to convert 3D solids with a zero thickness into 2D geometry. When this check box is clear, 3D solids with a zero thickness are discarded. 428 | Chapter 17 Autodesk Navisworks Reference
