All my setup are in metric. I always use metric and this is how my projects in CC are.
I know it is possible to create a tool in metric in the tool library. When I look at the config of a tool in a project, it is in metric.
But How can I see all tool parameters in metric in the tool database? It is always showing in inch.
Alternately, duplicate a tool library, then do About | Carbide Create | Open Data Directory and edit the duplicate using a spreadsheet to create a .csv file which has metric versions of the tools in question.
