Metsec cold rolled - Important information

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

Drawings

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

Procedure

  • Navigate to Drawings & reports --> Create drawings --> Master drawing catalog
  • 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 Metsec objects within the model select the Create drawings for all parts

Standard Assembly drawing properties

  • CR_metacnod - Accessory (no order data)
  • CR_metsecac - Accessories
  • CR_metsecc - Channels
  • CR_metseccl - Cleader Angles
  • CR_metseceb - Eaves Beams
  • CR_metsecp - Purlins

Standard Single-part drawing properties

  • CR_metpart - Metsec single parts

Notes

  • Even if you are just sending Tekla Structures drawings to Metsec, running the file transfer macro has the advantage of trapping errors in the Tekla Structures model, for example interactively defined bolts off gauge lines.
  • The following Metsec parts are only modelled as representations within Tekla Structures. Therefore no physical representation will be shown in the drawing for these items, only the order data.
    1. Speed-Fix strut - order length = hole centres
    2. Diagonal Ties - order data as order forms

Profiles

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). Always consult the catalogue or the Tekla Structures profile database if you are unsure of the actual dimensions.

  • C-Section rails, floors etc., e.g. MET-2-202C20 is 202mm deep with 65 mm flange and 2mm thickness.
  • Zed Purlins/rails, e.g. MET-2-142Z20 is 142mm deep with 55mm top flange, 52mm bottom flange and 2mm thickness.
  • Eaves Beams, e.g. MET-2-EB170E23+05 is 170mm deep with 2.3mm thickness and 5 degree flange slope. (Note last three figures indicate flange slope “0” to “20”)
  • Historical profiles - In the profile catalogue there are old profiles under both the Z Profiles, C Profiles, Eaves Beams, these should not be used as they are for backwards compatability only.

Connections

Any joints which are specific to Metsec 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:

Macros

The standard roof and wall 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.
