<div>A bead is a small, decorative object that is formed in a variety of shapes and sizes of a material such as stone, bone, shell, glass, plastic, wood, or pearl and with a small hole for threading or stringing. Beads range in size from under 1 millimetre (0.039 in) to over 1 centimetre (0.39 in) in diameter.</div><div></div><div></div><div>Beads represent some of the earliest forms of jewellery, with a pair of beads made from Nassarius sea snail shells dating to approximately 100,000 years ago thought to be the earliest known example.[1][2] Beadwork is the art or craft of making things with beads. Beads can be woven together with specialized thread, strung onto thread or soft, flexible wire, or adhered to a surface (e.g. fabric, clay).</div><div></div><div></div><div></div><div></div><div></div><div>cst bead lot download</div><div></div><div>DOWNLOAD: https://t.co/f2Ze7FnxyB </div><div></div><div></div><div>Beads can be divided into several types of overlapping categories based on different criteria such as the materials from which they are made, the process used in their manufacturing, the place or period of origin, the patterns on their surface, or their general shape. In some cases, such as millefiori and cloisonn|- beads, multiple categories may overlap in an interdependent fashion.</div><div></div><div></div><div>Beads can be made of many different materials. The earliest beads were made of a variety of natural materials which, after they were gathered, could be readily drilled and shaped. As humans became capable of obtaining and working with more difficult materials, those materials were added to the range of available substances.</div><div></div><div></div><div>The natural organics include bone, coral, horn, ivory, seeds (such as tagua nuts), animal shell, and wood. For most of human history pearls were the ultimate precious beads of natural origin because of their rarity; the modern pearl-culturing process has made them far more common. Amber and jet are also of natural organic origin although both are the result of partial fossilization.</div><div></div><div></div><div>The oldest-surviving synthetic materials used for bead making have generally been ceramics: pottery and glass. Beads were also made from ancient alloys such as bronze and brass, but as those were more vulnerable to oxidation they have generally been less well-preserved at archaeological sites.</div><div></div><div></div><div>Many different subtypes of glass are now used for beadmaking, some of which have their own component-specific names. Lead crystal beads have a high percentage of lead oxide in the glass formula, increasing the refractive index. Most of the other named glass types have their formulations and patterns inseparable from the manufacturing process.</div><div></div><div></div><div>Small, colorful, fusible plastic beads can be placed on a solid plastic-backed peg array to form designs and then melted together with a clothes iron; alternatively, they can be strung into necklaces and bracelets or woven into keychains. Fusible beads come in many colors and degrees of transparency/opacity, including varieties that glow in the dark or have internal glitter; peg boards come in various shapes and several geometric patterns. Plastic toy beads, made by chopping plastic tubes into short pieces, were introduced in 1958 by Munkplast AB in Munka-Ljungby, Sweden. Known as Indian beads, they were originally sewn together to form ribbons. The pegboard for bead designs was invented in the early 1960s (patented 1962, patent granted 1967) by Gunnar Knutsson in V|nllingby, Sweden, as a therapy for elderly homes; the pegboard later gained popularity as a toy for children.[3] The bead designs were glued to cardboard or Masonite boards and used as trivets. Later, when the beads were made of polyethylene, it became possible to fuse them with a flat iron. Hama come in three sizes: mini (diameter 2 mm (0.079 in)), midi (5 mm (0.20 in)) and maxi (10 mm (0.39 in)).[4] Perler beads come in two sizes called classic (5 mm) and biggie (10 mm). Pyssla beads (by IKEA) only come in one size (5 mm).</div><div></div><div></div><div>Modern mass-produced beads are generally shaped by carving or casting, depending on the material and desired effect. In some cases, more specialized metalworking or glassworking techniques may be employed, or a combination of multiple techniques and materials may be used such as in cloisonn|-.</div><div></div><div></div><div></div><div></div><div></div><div></div><div>Most glass beads are pressed glass, mass-produced by preparing a molten batch of glass of the desired color and pouring it into molds to form the desired shape. This is also true of most plastic beads.</div><div></div><div></div><div>A smaller and more expensive subset of glass and lead crystal beads are cut into precise faceted shapes on an individual basis. This was once done by hand but has largely been taken over by precision machinery.</div><div></div><div></div><div>"Fire-polished" faceted beads are a less expensive alternative to hand-cut faceted glass or crystal. They derive their name from the second half of a two-part process: first, the glass batch is poured into round bead molds, then they are faceted with a grinding wheel. The faceted beads are then poured onto a tray and briefly reheated just long enough to melt the surface, "polishing" out any minor surface irregularities from the grinding wheel.</div><div></div><div></div><div>If the glass batch is used to create a large massive block instead of pre-shaping it as it cools, the result may then be carved into smaller items in the same manner as stone. Conversely, glass artisans may make beads by lampworking the glass on an individual basis; once formed, the beads undergo little or no further shaping after the layers have been properly annealed.</div><div></div><div></div><div>There are also several ways to fuse many small glass canes together into a multicolored pattern, resulting in millefiori beads or chevron beads (sometimes called "trade beads"). "Furnace glass" beads encase a multicolored core in a transparent exterior layer which is then annealed in a furnace.</div><div></div><div></div><div>More economically, millefiori beads can also be made by limiting the patterning process to long, narrow canes or rods known as murrine. Thin cross-sections, or "decals", can then be cut from the murrine and fused into the surface of a plain glass bead.</div><div></div><div></div><div>This is the most common shape of beads that are strung on wire to create necklaces, and bracelets. The shape of the round beads lay together and are pleasing to the eye. Round beads can be made of glass, stone, ceramic, metal, or wood.</div><div></div><div></div><div>Square beads can be to enhance a necklace design as a spacer however a necklace can be strung with just square beads. The necklaces with square beads are used in Rosary necklaces/prayer necklaces, and wooden or shell ones are made for beachwear.</div><div></div><div></div><div>Elk rib bones were the original material for the long, tubular hair pipe beads.[5] Today these beads are commonly made of bison and water buffalo bones and are popular for breastplates and chokers among Plains Indians. Black variations of these beads are made from the animals' horns.</div><div></div><div></div><div>Seed beads are uniformly shaped spheroidal or tube shaped beads ranging in size from under a millimetre to several millimetres. "Seed bead" is a generic term for any small bead. Usually rounded in shape, seed beads are most commonly used for loom and off-loom bead weaving.</div><div></div><div></div><div>Tibetan Dzi beads and Rudraksha beads are used to make Buddhist and Hindu rosaries (malas). Magatama are traditional Japanese beads, and cinnabar was often used for making beads in China. Wampum are cylindrical white or purple beads made from quahog or North Atlantic channeled whelk shells by northeastern Native American tribes, such as the Wampanoag and Shinnecock.[8] Job's tears are seed beads popular among southeastern Native American tribes. Heishe are beads made of shells or stones by the Kewa Pueblo people of New Mexico.</div><div></div><div></div><div>Beads are thought to be one of the earliest forms of trade between members of the human race. It is believed that bead trading was one of the reasons why humans developed language.[9] Beads are said to have been used and traded for most of human history. The oldest beads found to date were at Blombos Cave, about 72,000 years old, and at Ksar Akil[10] in Lebanon, about 40,000 years old.</div><div></div><div></div><div>After shaping, glass and crystal beads can have their surface appearance enhanced by etching a translucent frosted layer, applying an additional color layer, or both. Aurora Borealis, or AB, is a surface coating that diffuses light into a rainbow. Other surface coatings are vitrail, moonlight, dorado, satin, star shine, and heliotrope.</div><div></div><div></div><div>Faux beads are beads that are made to look like a more expensive original material, especially in the case of fake pearls and simulated rocks, minerals and gemstones. Precious metals and ivory are also imitated.</div><div></div><div></div><div>I want to add a bead to a sheet metal part. It will follow the contour of another feature already placed. I could do a form tool and punch it in the part but I was hoping there is another way. I would like to sketch my trajectory on the part and have a the shape sweep that. But so far I dont see a way.</div><div></div><div></div><div>Looking at other cad packages It looks like they have a feature specifically for beads. I dont see this in Creo. I dont like form features either but since it would take more work to make the feature come out correct without a form tool , and I will be needing a very similar feature in a few other other parts Im afraid the form tool is what I will have to use. PTC reallly needs to add funcitonality for a bead feature. Thanks.</div><div></div><div></div><div>I just made a quick look for beading in other packages; only found it so far in NX NX Sheetmetal 18 BEAD - YouTube and SolidEdge Solid Edge Short: Sheet Metal in Solid Edge ST6 - YouTube courtesy of a compliant that Inventor did not. Overdue Improvements to Inventor Sheet Metal: - Autodesk Community which is a really interesting list of things for sheet metal to do. I did notice that the Solidedge version is unrealistic in its handling of sheet metal - the beads would certainly collapse if they were bent like the model shows.</div><div></div><div></div><div>To recap. I have an irregular shaped cuttout that I wanted a bead around all but one side of it. I did an offset sketch to use as a trajectory. To get the ends of the form to work I did two additional sketches at each end that were normal the original sketch causing the trajectory to go into the z direction. I did a sweep using a surface. Then used the Quilt Form selecting the surface I just created. I did not have to do any surface trimming or merging. Im not great at describing stuff but hope that gets it.</div><div></div><div> 31c5a71286</div>
