I think we need to separate discussion of defaults for the GUI from defaults for command line d.vect. Last time I checked the GUI uses size=5 filled circles for centroids. As I've complained before, this can be misleading if the data is a coastline with many small offshore islands which are smaller than the centroid circle. It effectively generalizes the offshore islands into circles and is easy to miss. I do like the circle as the default point feature symbol, but prefer the "x" as the default centroid symbol. In the GUI I prefer the centroids not be drawn by default, but I prefer d.vect from the command line to draw centroids. No idea how to make that happen, outside of feature type tabs and multiple d.vect calls from the WxGUI. Helena: > > (maybe make the default red as the default fill is grey).

Some time ago I added D_symbol2(): * The same as D_symbol(), but it uses a primary and secondary color * instead of line and fill color. The primary color is used to draw * stroke lines (STRINGs) and as the fill color for polygons. The * secondary color is used for polygon outlines. d.vect uses it for -c random colors. try: d.vect -c bugsites size=5 d.vect -c bugsites size=10 icon=basic/triangle neat, huh? Also you may notice that d.vect -c does some other magic, e.g. for the spearfish "fields" map, the areas are filled with random color but the centroids (icon=any) and boundary colors are steady; vs bugsites where the symbol color changes.
