MI Buffering with Square Corners

[Jeroen Wagendorp]

When using the buffer command in MapInfo, the created buffer polygon has rounded corners at line endpoints and the ouside corners of polygons.  While mathematically accurate, this is a problem when digitizing agricultural spray blocks (crop dusting planes can't spray curves) and creating floor plans (building corners come out rounded).  Does anyone know of an easier way to square buffer regions other than reshaping the nodes or splitting the buffer with a square object?  Are there any simple line styles with squared endpoints?   Thanks in advance, Jeroen
