The following Route Zones display additional Standard category properties specific to their zone type.
Pipe Attraction Zone
The Pipe Attraction Zone models a volume that attracts pipes. It has a cost factor, which means that routes that lie within the Pipe Attraction Zone are less expensive than equivalent routes outside the zone. The Pipe Attraction Zone is similar to the Pipe Rack Zone in that it modifies the result of the routing calculation by attracting pipes but has fewer rules for layout and for joining and leaving the zone. See Pipe Attraction Zone Sheet in the Smart 3D Space Management Reference Data.
On Face
Defines on which of the six faces the pipe is to be routed. Refer to the coordinate system triad of your volume when selecting the face.
|
|
1 - West 2 - South 3 - East 4 - North 5 - Top 6 - Bottom |
In a Pipe Attraction Zone, the On Face property is not always obeyed if doing so will result in a change in the pipe routing. In other words, the software will not add bends to the route in order to force a pipe to run on the specified face. This behavior is in contrast to behavior of the On Face property in a Pipe Rack Zone. As such, we recommend that the On Face property always be defined for a Pipe Attraction Zone in order to avoid unpredictable behavior. If the property is left undefined, the zone will select any one of the four candidate faces as an appropriate default based on the Route Direction property. For example, if the Route Direction property is set to East, the software can choose Top, Bottom, North, or South faces as the default, whereas setting the Route Direction property to West can produce a different result.
Associated
Determines whether all pipes see the Pipe Attraction Zone as a candidate for routing, or only those pipes that explicitly reference the zone. If the value of the property is set to True, only those pipes with the Pipe Attraction Zone in their list of zones to use will do so. If the value of the property is set to False, all pipes will evaluate the Pipe Attraction Zone for use in routing.
Route Direction
Specifies the direction relative to the local coordinate system in which pipe will be routed. The Route Direction property defines the axis of the routed pipe, so an East value is the same as a West value, North is equal to South, and Up is equal to Down. It is unrelated to the direction of the pipe as it is routed between its From and To connections. For example, if a pipe is routed from West to East through a pipe attraction zone, the result is the same whether the Route Direction property is set to East or West. As pipes always run parallel to one of the pipe attraction zone axes, the route direction in a skewed or non-orthogonal rack is translated as the rack axis closest to the specified orthogonal axis. If a rack is at 45 degrees to orthogonal, the software uses the longer of the two candidate axes.
Cost Factor
Specifies the cost factor applied to pipe that runs through the Pipe Attraction Zone. Typically, the cost factor value is a number less than one. The lower the number, the more the zone attracts pipe.
Layout
Specifies how pipes are laid out.
Normal
Pipe is laid out within the pipe zone. The pipe runs parallel to the Route Direction property and is on the face specified by the On Face property. The Normal layout is the default.
Surface
Pipe is laid out on the outside surface of the zone. For example, this applies when modeling a floor or wall on which pipes run.
WayPoint
A single pipe runs through the geometric center of the pipe zone. This mode is used to cause a pipe to run through a particular point in space.
Pipe Avoidance Zone
The Pipe Avoidance Zone models a volume that the pipe can enter if it is essential, but will avoid if possible. For example, it is not good practice for pipe to be placed within the immediate vicinity of a tank, but some of the pipes must connect to nozzles on the tank.
Cost Factor
Specifies the cost penalty applied to pipe that runs in the Pipe Avoidance Zone. Typically, the cost factor value is a number greater than one. The higher the number, the more the zone repels pipe.
Pipe Connection Zone
Pipe Connection Zones define a volume at which a route can terminate. They may act as obstruction zones (as defined by the Obstruction property) in addition to their special connection properties.
Connection Face
Specifies on which face the connection is made. The End and Surface values are intended for use with cylindrical connection zones, which support connection to the ends or the curved surface of a cylinder.
Obstruction
Specifies whether the zone allows pipes to be routed through it (value = False) or whether the zone allows pipes to be routed up to it, but not through it (value = True).
Pipe Rack Zone
On Face
Defines on which of the six faces the pipe is to be routed. Refer to the coordinate system triad of your volume when selecting the face.

1 - West 2 - South 3 - East 4 - North 5 - Top 6 - Bottom |
Associated
Determines whether all pipes see the Pipe Rack Zone as a candidate for routing, or only those pipes that explicitly reference the zone. If the value is set to True, only those pipes with the Pipe Rack Zone in their list of zones to use will do so. If the value is set to False, all pipes will evaluate the zone for use in routing.
Route Direction
Specifies the direction relative to the local coordinate system in which pipe will be routed on a rack. The Route Direction property defines the axis of the routed pipe, so an East value is the same as a West value, North is equal to South, and Up is equal to Down. It is unrelated to the direction of the pipe, as it is routed between its From and To connections. For example, if a pipe is routed from West to East through a rack, the result is the same whether the Route Direction property is set to East or West. As pipes always run parallel to one of the rack axes, the route direction in a skewed or non-orthogonal rack is translated as the rack axis closest to the specified orthogonal axis. If a rack is at 45 degrees to orthogonal, the software uses the longer of the two candidate axes.
Layout
Specifies how pipes are laid out.
At Edge
Pipes are laid out in joining order starting at each edge and working inwards.
Large Bore At Edge
Pipes are laid out in bore order starting at each edge and working inwards.
Spreadout
Pipes are laid out evenly across the rack.
At Center
Pipes are laid out in joining order starting at the center of the rack and working outwards.
Large Bore At Center
Pipes are laid out with the largest bore at the center and then working outwards.
Straight Through
Pipes are laid out going straight through the rack. This option allows modeling of wall and floor penetrations.
Allowed Fluid Codes
Filters the pipes that can use the zone based on fluid type. Only the fluid types you specify are permitted on the rack. If more than one fluid type is to be allowed, use a comma or a space to separate them. For example, type Process,Steam.
Cost Factor
Displays the cost factor applied to pipe that runs on the rack. The software calculates this value based on data you specify for properties in the Cost Estimation category. Typically, the cost factor value is a number less than one. The lower the number, the more the zone attracts pipe.
Position and Orientation
East
Displays the distance along the East-axis (X-axis) from the origin of the active coordinate system to the origin of the local coordinate system on the volume.
North
Displays the distance along the North-axis (Y-axis) from the origin of the active coordinate system to the origin of the local coordinate system on the volume.
Elevation
Displays the distance along the Elevation-axis (Z-axis) from the origin of the active coordinate system to the origin of the local coordinate system on the volume.
Bearing
Displays the angle in the XY-plane between the volume's x-axis and the active coordinate system Y-axis (North). Another way to describe bearing is the rotation of the volume about its z-axis. The bearing direction moves clockwise from North, where North is 0 degrees. Bearing is also known as compass heading. The bearing value is always positive, with a range of 0 to 360 degrees.
Pitch
Displays the angle in the XZ-plane between the volume's x-axis and the active coordinate system's X-axis. Another way to describe pitch is the rotation of the volume about its y-axis. Pitch is limited to between -90 degrees and +90 degrees, with 0 as horizontal.
Roll
Displays the angle in the YZ-plane between the volume's z-axis and the active coordinate system's Z-axis. Another way to describe roll is the rotation of the volume about its x-axis. The roll is between 0 and 360 degrees and is measured clockwise if you are looking West.
