To Connect Multiple Radiators to Parallel Pipes

1. Add valves to the connectors on a radiator (the source radiator) and create branch pipes that connect the radiator to a set of parallel supply and return pipes.
   

2. Select the source radiator.
3. Right-click, and click Connect Multiple Parts.
4. Select one or more target radiators, and press Enter.

   If the routing preference for a branch pipe does not specify a fitting for the connection, the Choose a Part dialog box prompts you to specify a different fitting.

   

   Tip: If you change a valve location on one radiator, run Connect Multiple Parts again to update all other connected radiators.

   The target radiators are connected to parallel pipes using valve types and branch pipe properties copied from the source radiator. The following rules apply:

   • Any existing valves or branch pipes are removed from the target radiator before it is connected.
   • The valves from the source radiator are copied to the target radiator.
   • The routing preferences from the source radiator branch pipes are used to create the branch pipes on the target radiator.
   • The target radiator is connected to the same parallel pipes as the source radiator. If the source radiator’s parallel pipes do not run parallel to the target radiator, the target radiator is connected to the nearest set of parallel pipes within a reasonable distance from the radiator.
   • The connectors on the source radiator are mapped to the connectors on the target radiator. For example, the valve and branch pipes attached to the lower-left connector on the source radiator will be copied to the lower-left connector on the target radiator. If there is not a direct one-to-one correspondence between the connectors on the source and target radiators, the software looks for the best possible match. If a match cannot be found, a connector on a target radiator might remain unconnected.
   • As much as possible, the connections between the systems specified for the parallel pipes are maintained. For example, if the Hot Water Return pipe system is connected to the right side of the source radiator, the Hot Water Return pipe system will be connected to the right side of the target radiator.
   • The connection to a target radiator can be adjusted even if the distance between the target and the parallel pipes differs from that of the source radiator.
   • Sometimes a target radiator cannot be connected.
