Civil3d 2012 Pipe Inverts at Structure walls Part 2

From the 2012 Installation Readme file
Pipes
Set Pipe End Location
This rule allows the user to set the location of the pipe ends at an offset relative to the structure's wall.
When AutoCAD Civil 3D pipes connect to structures they connect at the center of the structure. This is typically not an accurate representation of the real-world connection or pipe length. Traditionally, the connection issue is solved graphically by using part masking in the structure style, but this is not available when displaying a structure in profile as a solid. Also, the pipe slopes are currently calculated using the center to center length as opposed to the actual length of pipe.
When using this rule the user may specify the start and end locations of the pipes to be located at the structure center or at a specified offset relative to the structures inner or outer wall. The ends of pipes will be shown in plan and profile at these specified locations. Grips for the pipes will also appear at these locations. Slope values will be calculated based on the actual length of the pipes.
Note: When structures are moved, AutoCAD Civil 3D behavior is to reconnect attached pipes to the structures. The pipes will still default to the structure center and the user will have to Apply Rules in order to re-set the pipe end locations.
Parameters
The following parameters govern the behavior of the pipe Set Pipe End Location rule.

• End Location. Specifies that the end of the pipe be located relative to the Structure Center, Structure Inner Wall, or Structure Outer Wall. Without the rule pipe ends will be located at the Structure Center.
  
• Start Location. Specifies that the start of the pipe be located relative to the Structure Center, Structure Inner Wall, or Structure Outer Wall. Without the rule pipe starting ends will be located at the Structure Center.
  
• End Offset. Specifies an offset distance from the specified End Location toward the center of the ending structure. This offset is not applied when the End Location specified is to the Structure Center. Negative values and values that would extend the pipe further than the structure center are ignored.
  
• Start Offset. Specifies an offset distance from the specified Start Location toward the center of the starting structure. This offset is not applied when the Start Location specified is to the Structure Center. Negative values and values that would extend the pipe further than the structure center are ignored.

Known Issues
The following issue is a known behavior of the pipe Set Pipe End Location rule.

• Length - Center to Center. By default the actual pipe length is to the center, however, with the new "Set Pipe End Location" pipe rule the user can easily set the actual pipe length relative to the inside or outside edge of structures. The 2D Center to Center Length and 3D Center to Center Length values are actually the true lengths of the pipes in 2D and 3D respectively from start to end.
