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. To get twice the number of facets, double this value. To get half as many facets, halve this value. 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. Retriangulate JT Brep Models Select this check box to use BREP entities to create geometry. Clear this check box to use tri-strips to create geometry.

Sample Rate Specifies the frequency of points extracted from the input file. Increasing the sample rate, reduces the number of points extracted. As a result, the image resolution is reduced, and the file is converted faster. Point Colors Specifies how points are extracted from the input file. Select from the following options: ■ None - the points come through as white. ■ Raw Intensity - the points use the intensity values stored in the file. ■ Color - the points use the color values stored in the file. ■ Color-Mapped Intensity - the points use a spectrum of RGB colors. ■ Gamma Correction Intensity - the points use gamma-corrected raw intensity values stored in the file. Gamma Correction Level Specifies a gamma correction value used to adjust the normalized point intensity values obtained from the file, and results in lighter or darker images depending on the setting. A gamma correction value in the range between 0.1 and 0.99 adjusts the weighting of intensity values at the lower end of the intensity range, so that the image appears lighter. A gamma correction level above 1.0 has the effect of darkening the image. NOTE A gamma correction of 1 means no changes.

When this check box is clear, the file reader ignores line-geometry. Set Facet Circle Specifies the number of facets for arcs. Enter the number of straight line segments required to facet a whole circle. This option corresponds to the MicroGDS Set Facet preference. 426 | Chapter 17 Autodesk Navisworks Reference
