I admire Linux becasue of it's ability to make things non-interative, and automated. Batch processing is nice thing. OpenOffice may be used as headless, producing pdf from a OpenOffice file is possible. Scene may created in text file and script may be execited to render it and to produce a picture using renderer like Povray.
In that line, I wish to see and use FreeCAD, to produce finished drawing, after reading data, without launch of GUI.
Please suggest, if there is any way. If not, is there demand, other also thing that this feature may be useful. If yes, we may develop it.
