I was in the mood to model with Blender today, so I recreated a typical directional sign found in Future World at EPCOT. What I find interesting about this excercise is that the entire model is basically made out of primitives (cylinders, cubes, etc.) But when put together, the design looks really cool, thanks to the brilliant Disney Imagineers.
There are a few techniques worth mentioning, however. Refer to the figure below.
The outer frame is a cylinder, that was simply extruded around a corner. One end of the cylinder was rotated 45 degrees around the Y-axis, then extruded down the Z-axis.
The lattice work is made up of elongated cubes. All of them originally overhung the outer frame. I couldn’t find any kind of “slicing” operation, so I created another elongated cube to act as my slicing object. I positioned it where I wanted the slice to occur, then performed a Boolean Difference operation with each piece of lattice.
The outer cylinders, that will eventually hold the arrows that point to the associated attractions, are actually made up of three cylinders. I began with the first cylinder and deleted its end faces, so I basically just had a hollow ring. I duplicated the ring, then scaled it down to make an inner ring. On each end of this dual cylinder, I made faces between the inner and outer rings. I then created a third cylinder, kept its faces intact, and scaled it to fit inside the inner ring.
