SOLIDWORKS SNL Options File Guide

The Options File can be used to return a license back to the pool when the SolidNetwork License manager (SNL) sees inactivity on a client machine. This is especially helpful when administering PDM, giving a company a tremendous amount of flexibility on how licensing is handled.

This guide will show you the steps to create your own Options File using the SolidNetwork License Manager.
