Hi Marissa,
So cove.tool is a web based energy modeller that allows you to import your building from a number of 3D modelling apps (SketchUp, Revit, Rhino, etc) including Vectorworks, to analyze performance of a number of metrics - climate, glare , shadow, energy & water use, embodied carbon, emissions, etc.
Their Vectorworks plugin can be found here: https://www.dropbox.com/s/y9gdxnax6u88f4b/Covetool Plugin Installment.vwx?dl=0 - it contains a file that is a wrapped Marionette network containing the code for the plugin.There is a nice installation guide and short tutorial here: https://help.covetool.com/en/articles/5063718-vectorworks-plugin-workflow
As I mentioned above, there seems to be a hiccup after the install when it tries to install the Python modules.
Any help would be most welcome. This tool looks promising and powerful if we can get it to work as painlessly as possible!
