Autodesk Navisworks Reference 17 File Options Dialog Box Use this dialog box to control the appearance of the model and the speed of navigation around it, and also to create and configure links to external databases. When you modify any of the options in this dialog box, your changes are saved in the currently opened Autodesk Navisworks file, and apply to this file only. Menu: Tools ➤ File Options. Culling Tab Use this tab to adjust geometry culling in the opened Autodesk Navisworks file. Area Enable Specifies whether area culling is used. Number of Pixels Below Which Objects are Culled Specifies a value for the screen area in pixels below which objects are culled. For example, setting the value to 100 pixels means that any object within the model that would be drawn less than 10x10 pixels in size are discarded. Clipping Planes Near Automatic Select this radio button to make Autodesk Navisworks automatically control the near clip plane position to give you the best view of the model. The Distance box becomes unavailable. Constrained Select this radio button to constrain the near clipping plane to the value set in the Distance box. Autodesk Navisworks uses the provided value unless doing so affects performance (for example, makes the whole model invisible), in which case it adjusts the near clip plane position as necessary. Fixed Select this radio button to set the near clipping plane to the value provided in the Distance box. 401
