Yes. Still alive, and wanting suggestions. Assuming I do not need to patch the downloaded version for any reason, the next version should have what you want.
Currently working on "Trepanning" using sharp or button style tools with width and radius compensation. Time has been short recently, but will keep on it.
Once this is done, and working right, the work done is 95% of what is required for your finned cylinders etc.
Will try and include both when ready, but no date yet.
