Grass allows all types of vector geometry to exist as one vector map; you may edit
and change the attributes of any point, line, area, boundary, and centroid as you wish.
Many Grass vector modules have a 'type' parameter that lets you control what vector
geometry you wish to modify (i.e., type=line, type=point, etc.).

Can you explain the specific problem you're encountering? Please list the exact commands
you entered.
