18. Now we need to link the parameters we setup to adjust the louvre in the previous family so
we can adjust the louvre in this one. Select Family Types as we need to add parameters into this family that we can
link. In the parameter menu select New and create parameters for louvre depth, thickness, angle and material. There
is no need to create one for the width as we will just use the Width already defined. Make sure all parameters are
selected as Type parameters and their type is correctly selected, that is angle for the angle, length for
thickness/depth and material for the material. Note: The parameters do not have to have the same name. You will
notice that the length and angle parameters default to 0. Before we can link them we must set realistic values
otherwise we will have errors. Once complete click OK and go to a plan view. Now, select the Louvre and go to it's
properties and click the Edit/New tab. Next to each parameter in the far right column select each parameter then
link to the appropriate parameter in this family.

19. Now we have setup these properties we need to setup the louvre in elevation. Go to the Left
Elevation. You will notice at the moment the louvre is sitting on the ground. Place a dimension from the lowest
point of the louvre up to the sill reference plane. Now select the louvre and change the dimension to 0 then lock.
