Metsec Diagonal Ties (27)

The Metsec Diagonal Ties macrosaved series of actions that includes instructions for a program

Macros are located in the applications and components catalog. They are recorded or created manually and stored as .cs file in a folder defined with the advanced option XS_MACRO_DIRECTORY.

Macros can, for example, be used for creating drawings or reports.

Macros are sometimes used to run an application.

allows the placing of one or two diagonal tie wire or angle between any two or three selected bolts.

  • It is important to realise that any modification of the parts to which this macro applies is likely to cause incorrect results in the model. This is because the items created by a macro are not redefined when changes are made to the previously selected members. If the diagonal tie bracket is placed using the Below option then suitable modifications will be made to the lengths of the side rail support or anti-sag bar. These will not revert back to their original state if the diagonal tie is subsequently deleted and so they should be reapplied again after the removal of a diagonal tie. 
  • To reduce unnecessary parts in the models/clarity the end brackets are not modelled.
  • When three bolts are selected, the middle bolt must be to the lower cleat on the restraint. A pair of diagonal ties will be positioned between the bolts, fitted under the end cleat and the strut will be shortened accordingly. If two bolts are selected then the tie will be connected on top of the end cleat. The holes will normally be:
  1. The purlin / rail cleat bolt nearest the rafter / stanchion (or the inside bolt in the anti-sag / side rail support cleat) for the top of the tie
  2. Either bolt in the anti-sag / side rail support cleat for the bottom of the tie
  • For certain applications, e.g. panel joint rails and heavy side rail supports, it is necessary to offset the brackets for the diagonal ties from the bolts in the side rail support or anti-sag cleats. This is done by setting one or both of the Offset Hole parameters rather than defining an extra pair of holes interactively, i.e. still select the bolt in the cleat. For those applications, it will be necessary to select the correct tie type as Tekla Structures will NOT do this automatically.
  • The Metsec diagonal tie is designed to cater for angles between 25 degrees and 65 degrees but the macro will allow the tie to be placed for angles between 10 degrees and 80 degrees.
  • To apply the macro select two appropriate bolts from the model. Both bolts must pass through a rail.

Selection order example

When selecting a bolt ensure both Select bolts  and Select objects in components  are turned on.
When selecting a point ensure Select all  is turned on.

  1. Bolt
  2. Bolt
  3. Bolt (if required)
  4. Click middle mouse button
