Charles Francis Annesley Voysey’s Homestead is consisted of second floor with various gable roofs. Even though floor plans are simple, creating gable roofs were a little bit complex. At first, by using floor plans from a phaidon book, I adjusted scale. After that, I imported dwg files from auto cad at every floor and a site plan. After creating walls, floors, and ceiling, I created gable roofs by using roof by footprint, roof by extrusion, join and join roof.
The picture in Figure 1 shows the outcomes of Charles Francis Annesley Voysey’s Homestead. Generally, it has “L” formation and a tilted roof. As a BIM-based parametric model that we have studied at class such as baluster, I tried to make a parametric window. There are many windows that have different dimension horizontally, which will be very helpful for me to understand BIM-based parametric model as well as to learn basic knowledge about the Revit program.
In the window parametric family, I calculated the number of mullion by using an array with variable, count_WidMullion. I assigned width and depth by using some variables such as Frame_HT, Frame_WT, Mullion_width, and so on. Also, I made some paterials such as Frame_M, Glass_M and Mullion_M which enables them to change after loading into the project. I made some formulas such as “W1=Width-Frame_WT” and “H1=Heignt/2-Frame_HT”.
The parametric design diagram and formulas can be seen from Figure 3.
