I just installed build 648 and tested the four new tools (Linear array, Circular array, Corner tool and Trim vectors). The Trim vectors tool is one of the best upgrades in a long time and very much needed, thanks Carbide3D.
I have one more item on my wish list, a tool to curve text easily. I seem to need it on occasion and end up using a third-party software to create an SVG file and importing into Carbide3D.
