Scale the entire scene: If it doesn't matter what units you work in, scale the entire scene so objects are not affected by viewport clipping. 1 Open the problematic scene and select everything. 2 On the toolbar, click Select And Uniform Scale. 3 Enlarge the entire scene. Not only do the objects in the scene get larger but the distance between objects increases. So, the larger you scale the scene, the further your camera is located from the surrounding objects. If you need to work in real world units, such as inches or meters, you should set the scale of the scene before you begin modeling by changing the System Unit Scale value from the default of 1 unit=1 inch to something like 1 unit=0.1 inch or even 0.01 inch. If you change the System Unit Scale after you have begun modeling, you will need to use the Rescale World Units utility to rescale the scene. Zooming and Panning Are Too Fast or Slow If zooming and panning are too fast or too slow, the most likely cause is the System Unit Scale. 3ds Max can exhibit round-off errors when dealing with extremely large or small distances. These round-off errors can also cause normals to be flipped or strange viewport clipping. 3ds Max does not have the numerical resolution to zoom infinitely from the some remote corner of the solar system down to an ant on your doorstep. If you're going to change the System Unit Scale, you should change it before beginning any modeling. If you do have to set it later, it's best to rescale the entire scene with Rescale World Units. For example, if working on a tiny scale, like modeling coins, you might change the System Unit Scale from the default of 1 unit=1 inch to something like 1 unit=0.1 or 0.01 inch. For larger scaled scenes, like an airport, increase the System Unit Scale. As a rule of thumb, keep the scale such that the smallest detail is not less than one generic unit. If this makes the scene too big to work with comfortably and efficiently, you can create separate scenes for models that include cameras for "close" and "far" shots. 7878 | Chapter 28 Troubleshooting 3ds Max
