Ayrshire cold rolled - Important information

When utilising the Ayrshire cold rolled system it is important to take the following information into account.


Orders can be made by file transfer and/or drawings. It is vitally important that you use the Drawing Wizard in conjunction with the pre-defined drawing settingssettings that control what the drawing looks like and what it includes

Drawing settings can be defined in the modeling mode when creating a drawing, and they can be modified in the drawing mode.

The range of the objects and elements that drawing settings affect may vary.

so that the correct orientations and order data is shown. Ayrshire may refuse to accept other styles of drawings.


  • Navigate to Drawings & reports --> Create drawings --> Master drawing catalogcatalog that is used for creating drawings by using master drawings

    Master drawing catalog can be used for searching for master drawings usually in the current model and saving the search results.

  • Select COLD ROLLED DRAWINGS folder
  • Right click on the drawing wizard in the box below the folder
  • To create drawing for the selected objects select the Create drawings option (ensure that Select object in components is selected)
  • To create drawings for all Ayrshire objects within the model select the Create drawings for all parts

  • If you are sending Tekla Structures drawings to Ayrshire, it is necessary to run the file transfer 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.

    immediately before creating drawings. This is because the Ayrshire data entry codes can only be determined for each beam / accessory by that macro. If you never run the macro, the codes will be blank and Ayrshire will take longer to process your order. If you make modifications to Ayrshire parts in the model and do not re-run the file transfer any drawings may have incorrect information in this field. 
  • Even if you are just sending Tekla Structures drawings to Ayrshire, running the file transfer macro has the advantage of trapping errors in the Tekla Structures model, for example interactively defined bolts off gauge lines.
  • You should be aware of the following differences between the Ayrshire detailing program, and the drawings produced by Tekla Structures, in case of any confusion over ordering.
    1. Purlin / Rail drawings do not mark the span centre-lines
    2. Zeta Purlin/Rail Cleats are not modelled with crank but the overall height and sheeting line are correct for ordering. Similarly, Zeta Stays are not modelled with crank but the overall length is correct.
    3. Eaves Restraint Brackets are modelled without the "kidney" holesmall hollow open throughout a part or assembly that is usually used for fastening parts with bolts or other such objects

      Hole is created in the same way as bolts and hole properties are defined in the bolt properties.

      . This is replaced by a simple round hole at the angle required for the strut.
  • The following Ayrshire parts are only modelled as representations within Tekla Structures. Therefore no physical representationthe way that the information included in a model is represented visually

    will be shown in the drawing for these items, only the order data.
    1. Sag Bars - order length = hole centres
    2. Heavy Duty Sag Bars - order length = hole centres
    3. Apex Ties - A, H and as detailing program
    4. Diagonal Braces - A and B as detailing program


In order to obtain the best results with the macros, please use the following profile types as indicated. Although not strictly necessary, the best results for ordering will be obtained by using the names "PURLIN" and "RAIL" in the Beam Properties dialogue in Tekla Structures, (otherwise drawings may be produced with the wrong orientations).

  • Zeta purlins/rails, e.g. AYR-ZETA-15017 is 150mm deep with 1.7mm thickness
  • Zeta II purlins/rails, e.g. AYR-ZETAII-22516 is 225mm deep with 1.6mm thickness
  • Zeta III purlins/rails, e.g. AYR-ZETAIII-17013 is 170mm deep with 1.3mm thickness
  • Zed purlins/rails, e.g. AYR-ZED-18515 is 185mm deep with 1.5mm thickness, and AYR-ZED-3025 is 300mm deep with 2.5 thickness
  • Eaves Beams, e.g. AYR-EB16020+06 is 160mm deep with 2mm thickness and 6 degree flange slope. (Note: last three characters indicate flange slope "+15" to "0")
  • CW Sections used as rails, trimmers etc., e.g. AYR-CW-14018 is 140mm deep with 1.8mm thickness
  • C Sections used as trimmers etc., but not rails, e.g. AYR-C16025 is 160mm deep with 2.5mm thickness
  • Valley Beams must be entered as Tekla Structures twin profiles. The system will allow any C-section profile to be used as a twin profilepart that represents two identical parts mirrored in relation to their position

    Twin profile can be separated into two individual parts, after which it is no longer a twin profile.

    , i.e. it is up to the user to specify the correct profile to be compounded, e.g. AYR-VB34025. However, they will need to be ordered from Ayrshire as two separate parts
  • Cleader rails, i.e. one of AYR-100*100L-CLEADER, AYR-50*50L-CLEADER, or AYR-60*35-CLEADER


Any joints which are specific to Ayrshire should always be used in preference to the equivalent general cold rolled joint or the joint for any other manufacturer. For additional help on the following, see the individual help files:


  • When using Cold Rolled Sleeve (119) Ayrshire's system assumes that standard sleeved and butted purlins / rails will have sleeve holes, even where no actual sleeve is required. Holes will be created unless Force Sleeve Holes option is set to NO under the parameters tab. 
  • All Zeta profiles can be used with Cold Rolled Overlap (126). They are omitted from Ayrshire's catalogue due to lack of space.
  • The Eaves Beam to Stanchion (113) joint will automatically use the stand-off or flush-face cleats depending on the relative location of the column and eaves beams. 


The standard roof and wallplate that represents a structure such as a wall or roof panel

In Tekla Structures, a panel is created by picking two or more points.

In cast-in-place concrete the term wall refers to a concept similar to panel.

macros are "modifiable". For these macros, a macro symbol, ("M" in a circle), will appear at the start of the first part selected for the macro, i.e. column or rafter. This works in the same way as a joint symbol, i.e.

  • Double clicking on the symbol allows the parameters to be changed to modify the created parts
  • Changes in the parts selected for the macro, e.g. changing the sheeting line, causes the macro to automatically modify the created parts
  • Selecting the macro symbol and deleting it, causes all the created parts to be deleted

However, you also need to take care when using these macros. In particular:
  • It is important to realise that in some cases (see the individual help files for details of each macro) any modification of the parts to which the macro applies is likely to cause incorrect results in the model, and also affect parts ordered. 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. Do not edit parts after they are created. 
  • You cannot select any parts created by the macro unless you have the Select objects in components option selected.
  • DO NOT simply delete the created parts and re-apply a macro if you make a mistake. You may end up with several macro symbols on top of each other, and several copies of each required support. If you select the wrong options, then find the macro symbol and modify the parameters, or if you have selected the wrong parts then you will need to delete it.
  • Sometimes when you apply a macro, no supports will be defined, e.g. default number in bay is zero, or validation error, but the macro symbol will still be defined. Again, DO NOT simply re-apply the same macro, or the non-standard one. In the first case, find the macro symbol and modify the relevant parameter. For the second case, either delete the symbol if you have selected the wrong parts, or correct the validation error, and the macro will automatically run again.
