Parametric Truss Issue

Truss A Create Driving Surfaces 1 Create Planar Triangle Faces 2 Draw Offset Curves and Fillet 3 Offset Curves by Area 4 Create Planar Surfaces and Render- Area Gradient 5

Here is my development of the Truss Assignment. First, the truss demo is different from the file that we got on class. I try to change the process of Grasshopper so it looks the same to the demo. But for some reason I don’t understand why the Rhino projection of the inside triangle are not in a void, it looks that is a complete surface instead?? Can some one help and tell me what I did wrong?

Round Two

In the second round of Grasshopping, I was able to control four drivers for the Chair One design:

1. Thickness of each rib
2. Degree of filleting between the ribs
3. Chair height
4. Seat tilt (I wasn’t able to separate the tilt of the seat from the tilt of the back of the chair so the whole bucket seat unit tilts independent of the legs)

Round One

Round One

I’m a little behind on my blog posting … These are images from my first round of Grasshopping to drive the Chair One design in different directions.

I was able to vary the rib thickness and the degree of filleting between the ribs, but my Grasshopper file looked (and smelled) like a mess …
