Sag Rod (Legacy)

Tool summary :

  • Can add the following sag rod types: straight, bent, straight+hook or bolt.
  • The sag rod custom member can add holes to processable members:

    • The sag rod custom member cannot add holes to miscellaneous members due to the fact that Process and Create Solids does not match holes to miscellaneous members.
    • Supported member types for adding holes: column, beam, vertical brace, horizontal brace, purlin, girt, custom girt.
    • Supported material types: W flange, W tee, tube, channel, angle, cold formed Z, cold formed channel.
  • A sag rod can be added in space, without a connecting member.
  • A Sag Rod icon can be added to your toolbar (classic) or ribbon (lightning). The icon, keyboard shortcut or context menu command can be found in the group named ' Model -- Member '. For lightning, Customize Interface is used to configure ribbons, keyboards, the context menu and modes.
  • Another way to launch Sag Rod is to press F2 > check the box for " Miscellaneous steel " > double-click " Roof Frame ."
  • This following example shows how to get a proper view for one situation. The same principles that are used in this example may apply to many different situations:
Suppose that you want to add a sag rod that puts holes in the center of the webs of these two toe-down channel girts, which are in perfect vertical alignment.
Snap to a vertical surface of one of the girts. In this example, the outside surface of the near side toe of the bottom girt is snapped to.
Use View > Relative Depth to move the work plane of your current view into the view depth by a value equal to half the depth of the girt. For this example, the Depth check " Out " distance was also adjusted.
Now, when you add a sag rod and locate -- for example -- an INCM point, that point will be at half the depth of the girt.

Locating work points and choosing a Rod Type :

Two work points are required to add a sag rod.

The two points can be in vertical, horizontal or diagonal alignment.

" Point1 " options for the 1st located work point are found on the left end of the Sag Rod window. " Point2 " options for the 2nd located work point are found on the right end of the Sag Rod window. Most options for " Point1 " and " Point2 " are the same. The " Connection Type " called ' Floor clip ' can only be applied on the " Point1 " half of the edit window.

After locating the sag rod's two work points, a rod type selection window opens. You must press one of the buttons to continue. Pressing the " Straight " or " Straight-Hook " or " Bolt " button opens the Sag Rod window. Pressing " Bent " results in your having to locate two bend points, one for each end, after which the Sag Rod window opens.

Note in the above examples that the point 1 end is the bottom end. Be aware that if point 1 was the top end, the hook for the ' Straight hook ' type would be on the top end, and the bolt head at the bottom end of the " Bolt " type would be at the top end, and so on ....

Some options found on the Sag Rod window :

VIDEO Beginning with v2018, SDS2 has replaced the SagRod (BV) distributed custom member with the Sag Rod custom member. This video shows the adding of SagRod(BV) members to girts, Member Copy to make copies, the adding of a bent sag rod, a sag rod to a girt and beam, and more. Much of what this video shows can now be accomplished with the new sag rod custom member. (Recorded in SDS2 Detailing , v7.3.)

Custom members such as the sag rods shown here look and behave much like regular members, but are actually generated using Python-based plugins.
