SOLAR GAIN: how to manage with oriented solarshades

My first curtain wall is a facade with a sunshading system made by wood board (with a defined orientation).

I have to manage different parameters, in different family templates. A long process with a precise order. To explain it I will describe how to prepare curtain panel and how to "bring" the orientation parameter from the first family to the final project.

Here the two components of the sunshade: a wood board and a steel support.

About inclination of the elements. The components' families have reference planes for the extrusion with two reference angles. They ensure to manage the inclination of the elements maintaining the mutual positioning of the planes. (Without the correspondence of the two angles the "constraints are not guaranted").

I load the families in a single "mother", the sunshade component. This family has two paramers, the length of the component (that rules also the boardlength) and the inclination of the component. The parameter "angle" of the elements (in the Properties Panel) are associated to the family parameter "inclination" . The "length" parameter of the board (in the Properties Panel) is associated to the "boardlength" parameter of the mother family (depending by the "length" family parameter).

Now I load the family in a new one, where I run the array of the sunshades.

First I make the array of the element with a defined numer (with an associated "#boards" parameter).

The family has also other parameters that will allow me to modify the "arraylength" and "arrayheight". Also, the "sunshadeorientation" rules the "orientation" property parameter of the single component.

Notice: about the Alignment. For the length I aligned the signle component to the center axis (!) and matched the "sunshadelength" property parameter of the component to the "arraylength" family parameter. Then I align the array top/bottom and left/right parts to the family top/bottom and left/right axis.

I load the array family in a Curtain Panel family  and I align the array element with the main axis of the template (that have their own parameters).

The orientation of the sunshading system (the "sunshadeorientation" property parameter) is matched with the "sunshadeangle parameter". This way, when I select the single panel in the Curtain Grid I can modify the angle in the Properties.

The panel is ready. (I know it seems I make a redundant step making a family only for the array but without this in the final curtain wall the dimension were not respected!)
