The machine is for Santiago Perez's Fab Lab at the Fay Jones School of Architecture at the University of Arkansas

Some of Santiago's work with students can be seen here:

  The large Z axis allows for a variety of adaptive uses from utilizing the 5 axis for router carving of wood or foam masses as well as for plasma cutting large steel sections like I-beams and large tubes

Right:  Early model in AutoCad prior to switching to Rhino3d.

Right (next 4 images) :  Early model in AutoCad prior to switching  Rhino3d.  The geometry and configuration remained basically the same but was refined as fabrication progressed and issues were worked out.  The nice thing about ACAD was its powerful block tech.  It could essentially create your material/component lists with as much information as you wanted to input.  In the end, Grasshopper for Rhino works far beyond the block tech.

Right:  View of Rhino Model--wire frame view has its advantages.

Right:  View of Rhino Model--most modeling I do in ghosted mode.
