Stage 1:
Using Revit/Dynamo, I created a covered structure that could be used to provide shade in a park, or as the cover of an amphitheater, while being architecturally interesting. It is defined by 3 lines that are connected using the Surface.ByLoft node. Then, I added the rectangular panels on using the Surface.PointAtParameter node and inputting the 4-point rectangular panel adaptive component from our class folder.
Stage 2:
After completing Stage 2, the structure can now be varied parametrically in several ways. For example, using sliders, you can adjust the thickness of the panels, the coordinates of each of the two points that make up each of the three lines, and the height of the line in the middle (that determines the height of the structure). I used the Math.Sin function in the z-value of the middle/second line to make it more interesting, as you can control the amplitude and offset of the sine function. Overall, these sliders give the designer more control and the ability to play around with the shape and size of the covered structure, which are values that may change depending on the structure’s intended use. For example, if you set some values negative, you can get the structure to be concave up instead of concave down as shown in the image. If the z-value (height) of the lines is set to zero, then you’ll get a flat sheet (not very interesting).
