The Cladding configuration dialog

All of the options in this dialog box are explained here :

Profile Section - The profile shape and size that needs to be used for the new purlins/girts

Selection for the Beginning / End - This will set the position of the first purlin. For the roof purlins this would be the eaves of the structure, for wall girts this could be the ground floor or a concrete slab.

From the drop-down menu, there are the following options:

To Plane - Will allow you to select any column face of any profile or plate

To Grid line - Will allow you to select any grid line.

To Beam - Will allow you to select any beam.

To Column - Will allow you to select any beam. Use this for floor or apex configurations only

Start of Profile - This will measure from the start of the base profiles. This will be the selected columns in case of the wall cladding, or the selected beams in case of Floor or Apex configurations.

End of Profile - This will measure from the end of the base profiles. This will be the selected columns in case of the wall cladding, or the selected beams in case of Floor or Apex configurations.

Purlin placement - This will set the orientation of the purlin relative to the base profiles. From the drop down menus, there are the following options:

No Rotation - Accept the default rotation

Rotate follow-up row of purlins - Alternate every second purlin rotation

Rotate for Zed purlins with overlap - Zed purlins with an overlap will need a rotation for each instance

Purlin interruption - This will set the purlin span. From the drop down menus, there are the following options:

Interrupt at every location - Span the purlins between each base profile

Draw the purlins between the base members - This will draw the purlins flush : The top of the purlins will be coincident with the top of the base profiles. This also means that the purlins will be interrupted at each intersection with the base profiles.

No interrupts - This will span the purlins over the base profiles without any breaks

Skip interruption over some members - Do not break the purlins over a specified amount of base profiles.

Skip interruption over some members, Alternating - Same as above, but the breaks on the followup row of purlins will be alternated. If you use this then the interruption will not be placed on the same base profiles for all the purlins.

Number of members with no interruption - This option is to be used in combination with the above Skip interruption over some members options

Reverse the orientation of the purlins - This switches the start/end orientation of all the purlins




Edit the Purlin Brackets

There are likely to be numerous brackets and to edit them one at a time would take too long. It is however possible to edit all the brackets simultaneously.

Click on the Review macro icon and block select the entire roof structure.


This will open the macro edit dialog. At the bottom of the dialog, open the Groups drop-down menu and select Continuous purlin (the number in brackets is the number of macros included in the selection).
This will automatically open the relevant edit dialog.

Note! If the option for Interrupted purlin was chosen, it will be necessary to edit the brackets separately.

This method will work for any connection type or group.
