Can I still use WINFAP/ ReFH 2 with third-party tools if I switch to a network licence?

Yes, third-party tools that communicate with WINFAP and ReFH2 leave licence checking to WINFAP and ReFH 2, so are not concerned about whether a network or standalone licence is being used.

While the third-party tool is communicating with a network-licensed WINFAP or ReFH 2, the latter will occupy a network licence seat but should release it as soon as it has completed its calculations. How long this takes will depend on the size and complexity of your project.
