Sewer Profiles


Sewer Profiles is a drafting aid for drawing profiles of pipes and manholes.

To begin Sewer Profiles, Select DProad -> Sewer profiles.

Select an alignment (line, arc, or polyline) and place inlets, inlet manholes or manholes by station and offset. The blocks that are placed in the drawing are in the Dpsew directory and may be edited or redefined to meet your personal needs. Be sure to save a copy before you change them. The names must stay the same for the program to find them. When a structure is placed in the drawing a data block is also placed at the same point  (dpstruct.dwg). The name, station and offset fields will be filled in  automatically. You must fill in the rest of the data that you need (rim,  inverts, pipe size, etc.). Type DDATTE at the command prompt, select  the block and add or change any of the data. The alternate station and offset fields are to be used when a structure that is stationed along one alignment is the first structure along another alignment (a manhole at a street intersection for example). If this structure is selected first, the Draw profile and Write text commands will ask if you wish to use the alternate stationing.

If you do not use the Place Structure command you will have to place the block (dpstruct.dwg) on each of the structures in the drawing using Autocad's, or Intellicad's DDINSERT command. Use Autocad's, or Intellicad's DDATTE command to edit all needed data in the block.

NOTE: After using the blocks, the layer DP_STRUCTURE may be frozen to hide the data from being viewed in the drawing.

End sections or headwalls will have to be drawn by the user. Place the block (dpstruct.dwg) at the center of the structure. If the word END, HDWL, or HEADWALL appears in the structure description, a triangular shape will be drawn in the profile. Add the pipe diameter to the invert elevation for the rim elevation (the top of the end section or headwall).

After all necessary data has been added to the block (dpstruct.dwg) You may select the blocks by picking any part of the visible data text. Select from left to right in the order that you wish to have the profile drawn, or you may select in the order that you wish the note to be written.

NOTE: Structures must be selected before a profile can be drawn, or a note written.

Before drawing a profile you will need to set up a profile coordinate system. Use the Create profile UCS button, select a known point, enter station and elevation of known point and a name for the UCS. Be sure the scales are set correctly.

The Select UCS button may be used for moving between the profile UCS and the plan (world) UCS.

Select the Draw profile button and a profile is automatically drawn. If follow alignment is toggled on, the profile will be drawn along the alignment. If follow sewer is toggled on, the profile will start at the station of the first structure and measure the distance to the next structure. If the label buttons are toggled on the labels will appear on their own layers. The profile will be drawn on the current layer. Notations will use the current units precision settings of the drawing, set them to the desired number of  decimal places before drawing a profile. Labels will use the current text style.

NOTE: Pipe lengths are calculated from center to center of structure (the placement point for dpstruct.dwg) and are used to calculate the slope.

After one or more structures are selected the Write text command will write a text note of the structure which will be placed on the current layer. Text will be written with the current text style.
The note will be formatted as follows:
RIM (if manhole) E.P. (if inlet)
