Auto Hang

Layer(s): HANGERS, STEEL

Shortcut: AH

Associated: Setup

Ribbon: Insert Panel

An automatic routine for inserting one hanger on each selected pipe. The hanger attributes will be defined by the settings in Hanger Setup. No HydraCAD hanger command, this command included, spaces hangers according to NFPA 13 nor does any hanger ‘know’ where the next hanger is. Placement is solely up to the designer.

Select Armovers, Lines, Armovers and Lines, Mains, or All, depending on which pipes you want to hang. If the lengths are Computer Generated, and the same type of hanger is being used regardless of type of pipe, you can select All. Otherwise you should insert Lines and Mains separately.

By default, Auto Hang will reference HydraCAD steel layers, as represented by the STEEL* in the Steel Layers edit box.

If you have steel layers in addition to or different from the layers provided by HydraCAD, such as those from a background drawing, use the Pick Them button to pick and add them to the list. You can also add these layer names by typing from the keyboard. The layer names must be separated by commas if you type them in.

If you expect new hangers to replace any existing hangers in the same location, check the Erase Previous Hangers box. Enter values in the Shortest or Longest Pipe to Hang fields to set which lengths of pipes should be hung.

Press OK. Press Enter to process all pipes visible in the editing screen or just select pipes any way you like, such as a window. The selected pipe layers will be hung and all other layers ignored.

Hangers will be placed where steel intersects with the pipe if this point is close to the midpoint of the pipe. If this is not the case, hangers will be inserted at the midpoints of the pipes. All pipes without steel will receive one hanger. You should always double-check the layout generated by this command. In many cases you will have to insert more to meet building codes. In some cases, there are excess hangers that can be removed.
