Revit Surface

I then divded the surface up and placed a small pillow like component to give it an interesting texture.

I started by creating a wave like reference line and copying it over. I then changed the point heights to vary them and then lofted a surface over them.

22

23

Rhino Surface

Then I created a simple component and used the paneling 3D custom to create my surface.

I started by placing two flat surfaces that I then created a domain of points on so that i can later host geometry between them.

29

In Revit I started by designing my component which I would later array through a form to create my pattern. I wanted to create a frame like component which I started by creating 3 levels of reference planes which I then hosted mid lines. I then created a series of points on each line with the intent of hosting my frame geometry and giving it a smooth transition.

30

I then connected a spline system through the points to create my frame. Then I hosted reference circles on them at a parameritized radius.

31

I then created the pipes of the frame and joined them to create the final frame geometry for my component.

32

I then quickly created a form which I then copied in place to create the same surface twice. I then divided both surfaces which I hosted my component in. I mirrored the second surface to give me a double sided pattern.

35

In Rhino I started with the component which I constructed by created a bounding box that was then used to create 2 sets of splines that when mirrored create a pretty complex component which seems to weave through itself.

37

I then created two varying surfaces and then used the surface domain to break down the surface which I then placed my component into to create my final pattern.

41

I first created three elipses that i scaled and rotated in different ways to loft through an create my form. I then created a surface domain that will later host my frame geometry to rationalize the form created.

42

43

I then used the Paneling 2D diamond pattern to create my frames. I then filled in the gaps with triangular faces that I grouped with the rest of the frames so they could be numbered and layed out together.

44

Then I used the Paneling tool- Unroll faces which lays the frames out on the xy axis and labels them for lazer cutting. I then created a small rectuangular box and used it to measure and apply Planar lips to the forms which act as the glue surface in which to put the form together.

45

I also used a paneling grasshopper definition in which you choose the surface and the definition breaks up the form with triangular frames, numbers them, labels them and lays them out on an adjustable sheet that I then quickly baked to the correct layers and exported them for lazer cutting.

52

53

I started off with an elipse and and outside shape that I copied up and rotated around its center. I then lofted through the splines to create four surfaces that I joined together to create one form.

I changed the amout of divisions of the form into 16 planar surfaces in the xy plane and 7 planar surfaces in the vertical plane.

When put together they form the overall shape of the original form.

I then used a grasshopper definition to brake up this form into waffle like structure and then lays it out flat on the xy plane for lazer cutting.

61

In this assignment I wanted to create a fully paramatric tower form that is able to genereate a waffling system and lay it out for lazer cutting. I then wanted to create panels that would fit the waffles to create a skin for my tower form.

I started off by creating a quick translation vector and scaling control to control the array of a curve. I set the grasshopper deffinition up so that the only thing that the user has to do is draw an elipse and a point and grasshopper would do the rest for you.

62

The grasshopper definition lets you alter and scale the form however you want by the use of different graph mapping sliders in grasshopper. I then pluged the form B-REP into the previously created waffling definition which is also fully parametric allowing the user to alter their final waffling system real time and make many variations with little effort.

63

Once i finished the ribs in grasshopper the way I wanted them to look, I then baked all the forms to their layers in rhino and then I used the split command in rhino to split the outside form with the waffle ribs to create the outside panels.

64

65

I then used the smash tool to flatten the panels and lay them out and label them for lazer cutting.

I then exported the two lazer cutt files to cad and lazer cutt my final model. To be able to connect the pannels to the outside of my waffle form I decided to use a pin connection in each of the intersections of the waffles. To do this I scaled the original panels up a slight amount so that they would overlap and create a fish scale-like effect.
