yes, michalis, i have tried skin modifier,and also sculpting in blender,however this feels arkward, as there seems no shortcut key for changing the brush from add to substract ??.. (the obvious “alt”-key does rotate the view, have emulate mouse and numpad, as i work with a grahicstablet)… blender is so different from how things are approached, its really a steep learning curve, but i enjoy, and hope to find out much more…
EDIT and, as i thought it so odd, i searched more, and found its the "ctrl"key that changes from add to substract… thanks for asking michalis !!!
