How to create Form- Finding of parametric shell in architecture?
We begin with three different plans, using the xz plan component, plugin xz plan to plane component with defining the values x and y, this step gives us one surface plan with xy values in xz direction Fig. 6.7. We copy this xz plane twice in the y direction, to get three surfaces’ planes after that we have to reparametrize the surface, this step allows us to pick one point on the first surface which is on direction xz. Creating three different points on the xz geometry plan as surface number one, the first point is going to be on the bottom plane xz, the next point is going to be in the middle of the upper chord edge of plan xz, and the third point is going to be on the right side on the bottom corner of the xz surface plan. This step allows us to move freely all three points on xz surface plan, Then we get three different designs, after that, we interpolate the curves during this step we get the arch curve on each of the three surface planes, lofting all three arches together we get subsurface then we use hexagon component, with this component we can create a wireframe into subdivision u,v, then we use pipe component to define the dimensions of hexagon wireframe.
