Notes

• 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 it is necessary to change any of the members upon which the macro is dependent then first delete all the parts created by the macro, make the required changes and finally re-apply the macro.
• Most of the data required for this macro is fixed by Ayrshire 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.
• All purlin lengths must be parallel.
• All purlins must have the same offset from the rafter.

Selection order example

1. Purlin
2. Purlin
3. Pick a point or hole (the point must be a Tekla point object, rather than a snap point)
