To fix the position of the clipping planes 1 Click Tools ➤ File Options. 2 In the File Options dialog box, click the Culling tab. 3 Select Fixed for the Near clipping plane, and enter the desired value in the Distance box. 4 Select Fixed for the Far clipping plane, and enter the desired value in the Distance box. 5 Click OK. IMPORTANT Autodesk Navisworks uses the provided values even if doing so affects the system performance (for example, makes the whole model invisible). Make Objects Required Although Autodesk Navisworks intelligently prioritizes objects for culling in the scene, sometimes it drops out geometry that needs to remain visible while navigating. You can make sure the objects are always rendered during interactive navigation by making them required. To make objects required 1 Select geometry items that you want to remain visible during navigation in the Selection Tree. 2 Click Required on the Selection Tools toolbar. In the Selection Tree, the object appear red when required. TIP Clicking Required again makes the selected objects unrequired.
