More information about the Resource Manager can be found in the Help files here for VW2017 and here for VW2018.
If you would still like to or need to install Vectorworks Resource Libraries locally, for example if you will be working offline for extended periods of time or you anticipate you will have a very slow internet connection soon, you may do so using the information here.
