Notes

• Any modification of the selected parts will cause this macro to be updated.
• Most of the data required for this macro is fixed by Metsec and stored in a series of data files supplied with Tekla Structures. Where standard data is not applicable, then certain items can be modified through the Parameters tab of the properties panel, but it is also possible to tailor the data files to individual requirements. This would require assistance from Tekla Structures support.
• The order in which the purlins are selected will determine the up directionconnection or detail property that indicates how the created connection is rotated around the component secondary part, or the created detail around the component main part, relative to the current work plane
  
  The up direction options are +x, -x, +y, -y, +z, -z, and auto.
