![]() Here you can see the segments of the edge of the 3D cone and the flat pattern match as one would hope. Breech pieces Prisms Pyramids Right cone frustums Right cone truncations Pipe to cone branches. I would match things up with whatever number of sides you used when you made the cone. Unfold shapes, create 2D templates for fabrication. Note I used 24 sides for my circles and the arcs because that’s what you used. First, we initiated the git clone command. by the unfolded path as described and visualized in reference 5. A conformal cone parameterization is equivalent to flattening a smooth surface, like the sphere, over a polyhedron, which can then be cut and unfolded into. Syntax The command for this operation should look like this: git clone repo-url path/to/the/directory Here’s what we did. For my first example the only difference is there’s no need for the smaller circle. The mGGA results confirm the existence of the Dirac cone in an ideal AG previously. Next I used the Arc tool (not 2-Point Arc) to draw arc with 24 segments through 200.26° at the two radii and I connected their ends to get the face which I moved over to the right. (the line at the 3:00 o’clock position on the center circle.) I made a component of this geometry so the next geometry wouldn’t stick to it. The unfolding algorithm is smart and highly optimized for papercraft to minimize your effort in further editing. The application can generate 2D patches for your 3D models in a single drag-and-drop. Cones is a series of poufs by Jule Waibel, a German designer now based in London and in Stuttgart. Then I used the Protractor tool to place a guideline at 200.26° from the starting point. Unfolder is a 3D model unfolding tool for creating papercraft. Then I got the circumference of the larger circle (62.2) and did the following math. I drew a circle with a radius of 9.9 and the circle for the hole at 2.7 to match your truncated cone’s lower and upper circles. You also need the circumference at the bottom edge which you can get from Entity Info. You need the length of the side of the cone from the apex to the edge. Put in a radius r, angle, height y, and slant height, s. ![]() Draw lines from the ends of your arc to the arc center and that's your flat pattern. ![]() The length of that arc should the circumference you calculated. The length of the side will be the radius of an arc. I used the same method for yours with the added step of the center hole. Procedure First, draw the x, y-coordinate axes, then draw the cone, as shown in the featured image. Calculate the circumference of the cone's base and the length (not height) of the side.
