20. We are almost ready to do our array, but first we should check that everything functions
correctly. Go to the family types and change each value then click okay. If there are no errors and everything
changes as defined then your doing really well. If you have problems identify which parameter is causing the
problem and then go back a few steps and try to identify what you've missed (most likely it will be not
dimensioning to the correct point on the louvre/not using an origin point).
21. Once everything is working, in the left elevation, select the louvre and click Array. Now
you need to adjust the options at the top of screen as shown below. Group and Associate should be ticked, No. of
items 2, & Array to last. Now select the base array point as the upper most point of the louvre and, making
sure to stay vertical, select the head of the window as the finish point.

22. The next step is to add a parameter for the number of louvres. Right click on the line just
below the number 2 and choose edit label.
23. Now from the drop down menu that has appeared choose <Add Parameter...>. Now give the
integer a name (to maintain consistency with this tutorial call the parameter "No of Louvres".
24. Now we need to define the height extent of the top louvre. Add a dimension from the sill
reference plane to the highest point of the top louvre then select the dimension and change the dimension to be the
height parameter from the drop down menu at the top right of the screen. Now go to your Front elevation and add a
dimension from the left reference plane to the left side of the upper louvre and lock at 0.
