I create a line along the edge of the lower hexagon sides, and then use the Divide tool with 3 segments. + +I then create a rectangle plane, and align it to the 2/3d's segement, and do another boolean. + +I chose 22" as the height of the finished object, which fits onto a single sheet of 4' x 8' ply. + +To make it easier to work with the form, I draw guidelines at the base and the top so I know where center is. These intersections are the reference point for moving and scaling the object. + +Move the object to the origin, and draw a 22" inch line from 0 on the Y axis. We'll use this line to scale to. + +Then, I make trace all the edges, do 3pt orients, and align them to the cutting plane. + + + +## Creating Thickness + +We need to: +1. Offset mesh by .75 +2. Convert mesh to surfaces +3. Dup border edge to find curves +4. Loft inner curve to outer curve + +you only need to do this for each individual piece, and then duplicate them. + + + +## Measuring the Mitre Angles + +We need to draw some guidlines for measuring perpendicular to the edge of the face. + +[mitre angle edge measure] + +Then we measure the angle between the faces by typing "angle" in the command line, and selecting the beginning and ending of both lines. Then we find the mitre angle by dividing in half. + +For Support A, the hexagon-to-hexagon mating edge: +70.529 +/ 2 +35.2645 + +And for Support B, the hexagon-to-triangle edges: +109.471 +/ 2 +54.7355 + +We're going to use these angles to make some internal support triangle blocks. + + +You can create thes any way you like. I navigate inside my object and just build them in relation to the form. I also add notches in the side of the triangle that won't be mated, so there's no puzzle-piece confusing when we assemble. + +We'll need to make 18 of each. Duplicate them so we have 18 each, and lay them out for our cut. You can be as precise as you like in laying out your cutfile. I typically try to be conservative with the material. + +[cutfile image] + +Now, we lasercut! + + +[Metabeam Cutting Awesomeness] + +Now that the shapes are cut, we can mitre the edges. + +Using masking tape, I mark all the angles and lay them out. + +I'm using a 1HP Bosche Trim Router with a tilt add-on. + +This is an analog method of setting the angle, I typically error on the side of cutting more material away, because it's easier to fix a gap on the inside of the form, rather than the edges. + +[photos of setting the router angle] + +I cut all the edges one angle before setting the tool again. + +[cutting angles A] + +Now set the router to our additional angle + +[cutting angles B] + +We have one more special angle to cut, for the parts of the form that rest on the ground. + +[photo of cutting foot angle] + +We're done cutting! + + ## Assembly We'll work upside down, and build the form up.
