This command creates a single manhole from user selected points at the desired bottom and top locations of the manhole. The user specifies the horizontal and vertical scales, layer and drop across manhole. Other options include the manhole top and bottom width, top taper offset and the fixed taper height. The Top Taper Offset sets the distance from the top of the manhole to the point that the taper will end. A 2-foot offset on a 7-foot manhole is shown below. The Fixed Taper Height determines the overall length of the tapered section.
