Especially when the node which coincide with this parameter has complicated form planes, calculation time is shortened sharply.

Usually, the node close to the whole model size is rarely zoomed down until it has the necessity of a LOD display.

This parameter is not to create the LOD rough data of the node bigger than the indicated ratio to the whole model size.

A new parameter 'Node size to whole size in which LOD is not displayed (%)' is added for the improvement in efficiency of LOD rough data creation.

When starting sessions and carry out file management, RTC license feature is required.
