PERSPECTIVECLIP

Determines the location of eyepoint clipping. The value determines where the eyepoint clipping occurs as a percentage. Values can range between 0.01 and 10.0. If you select a small value, the z values of objects will be compressed at the target view and beyond. If you select a value such as 0.5%, the clipping will appear very close to the eyepoint of the view. In some extreme cases, it might be appropriate to use 0.1%, but it is recommended to change the setting to a higher value such as 5%.
