Terminology
Part is a generic term. In some case, it refers to an instance, and in other cases, it refers to a reference.
TerminologyPart is a generic term. In some case, it refers to an instance, and in other cases, it refers to a reference. Part PlacementYou can complete part placement in two steps:
You can execute these two steps in any order. When you select the raceway part reference, the default option is Define part sub type or select a new part. The last selection option you used is not memorized. If you go on placing the raceway part reference you have selected, you will always place the same raceway part. Placement of Multiple InstancesTo place multiple instantiations of the same reference, double-click the command. A single click lets you place only one instance of a reference and exits the command. ResizeSome parts, in most cases a reducer, require a resize of the network. In this case, the Propagate Size command is available. For more information, see Resizing the Network. Eccentric PartsWhen placing an eccentric part, you must comply with the following behaviors:
Default OrientationA part is placed on a network according to different parameters. When you place a part on a port, the nominal size value of the port is used to connect the ports with the same value. For example, when placing a reducer, it is automatically oriented to connect the port that has the same nominal size. Instantiation RuleThe Instantiation Rule attribute is taking into account during the part placement. Depending on the value of this attribute, the behavior is as follows:
In the case of a cut elbow, the behavior of Reuse or New Reference is managed automatically through the Reference Bend Angle attribute:
For more information, see About Cut Elbow. Filtering Rules for Elbow and Cut ElbowWhen using the Place Part on Port or Node command, consecutive filters are applied (if required) according to the values of the Instantiation Rule, the Reference Bend Angle, the Bend Radius and the Guidance for HVAC and raceway parts. The following table shows the different values that the filter uses to retrieve the elbow or cut elbow to place on the route.
For the first filter, the Instantiation Rule is the Reuse Reference, the Reference Bend Angle is equal to the Turn Angle, the Bend Radius and the Guidance values are computed from the route. If no part was found, a second filter is applied: the Instantiation Rule is the Reuse Reference, the Reference Bend Angle and the Bend Radius are 0 and the guidance is horizontal. This filter is used for old data. If no part was found with the second filter, a third filter is applied: the Instantiation Rule is Reuse or New Reference, the Reference Bend Angle is higher or equal to the Turn Angle, the Bend Radius and the Guidance values are computed from the route. If no part has been found with the third filter, a last filter is applied: the Instantiation Rule is New Reference and the Reference Bend Angle is higher or equal to the Turn Angle, the Bend Radius and the Guidance values are computed from the route. Parametric PartsA parametric part is a part or a route that can adapt its dimensions accordingly to the dimensions of the object to which it is connected. A parametric part is defined following the criteria described in Raceway Object Definition. You need to verify the Allow Search for Route with Instantiation Rule = NewReference preference to allow the search of a parametric part when no standard part was found. Parametric parts have a specific behavior when using the part placement, routing, or resize commands. RoutingThe following table describes the behavior of the parametric parts or routes when you connect a part and route during the routing command.
Standard behavior: the reference of the new object is searched in the specification based on the dimensions of the selected object. Part PlacementThe following table describes the behavior of the parametric parts during the part placement.
Standard behavior: the reference of the new object is searched in the specification based on the dimensions of the selected object. When placing parametric parts that adapt to fit a part selected in the 3D area, the parametric part is connected to the port. A coefficient is calculated and applied to the other ports to keep the same proportions as the original parametric part. ResizeDuring the resize command, the parametric parts in the network are modified according to the size of the connected objects on the ports. |
