> I do thing that the list of linetype/subtypes could be improved.
I agree at this point. -subtype option comes from times, when we had intention to make things universal and complex (and complicated :) . I'm not sure, but my feeling is that option -subtype should be removed at all. The reason is simple. If you do not specify the subtype, some subtype is assumed as default anyway. So it is just complicating things. I think, having types: wall wall-blocks wall-sand wall-debris would be better, than specifying all the time the subtype. What do you think? S.
