here is no pressure pipe tool in AutoCAD® Civil 3D®… or is there? Let’s think about this. Pressure pipe is first positioned horizontally, then vertically. If there is a change in the horizontal plan, the vertical plan needs to reflect that change. At times, pipes need to be designed using horizontal and vertical curves. Conflicts need to easily be factored in and navigated around. When there is a change in pipe size, pipe views need to update graphically. When pipes are deflecting greater than a given angle, a notification is needed. Structures need to be oriented to the pipe in the profile view, not the profile view itself. Annotation needs to be dynamic.
HORIZONTAL LAYOUT A lot of great beginnings occur in Civil 3D with an alignment. We use alignments to base the design of roads, sewers, and any other design item of considerable length and typical cross section. Pressure pipe fits those criteria. Alignments by design are easily plotted and profiled. 18 www.augi.com
