Create Meshes (Concept)-Autodesk AutoCAD 2008 Users Guide-kxcad

You can create polygonal mesh forms. Because the faces of the mesh are planar, the mesh can only approximate curved surfaces.

You can use meshes if you need hiding, shading, and rendering capabilities that wireframe models cannot provide but do not need the physical properties that solid models provide (mass, volume, center of gravity, moments of inertia, and so on).

You can also use meshes to create geometry with unusual mesh patterns, such as a 3D topographical model of mountainous terrain.

The visual style controls how a mesh is displayed, either wireframe or shaded. (VISUALSTYLES command) You can create several types of meshes.

 3D face. 3DFACE creates a planar mesh with either three or four sides.

• Ruled mesh. RULESURF creates a polygon mesh representing the ruled surface between two lines or curves.
• Tabulated mesh. TABSURF creates a polygon mesh representing a general tabulated surface defined by the extrusion of a line or curve (called a path curve) in a specified direction and distance (called a direction vector). 
• Revolved mesh. REVSURF creates a polygon mesh approximating a surface of revolution by rotating a path curve or profile (lines, circles, arcs, ellipses, elliptical arcs, polylines, or splines, closed polylines, polygons, closed splines, or donuts) about a specified axis.
• Edge-defined mesh. EDGESURF creates a polygon mesh approximating a Coons surface patch mesh from four adjoining edges. A Coons surface patch mesh is a bicubic surface interpolated between four adjoining edges (which can be general space curves). 
• Predefined 3D mesh. 3D creates three-dimensional polygon mesh objects in common geometric shapes, including boxes, cones, spheres, tori, wedges, and pyramids. 
• General meshes. 3DMESH and PFACE create three-dimensional polygon mesh objects in any shape.

3d structures constructed out of identical panels I digital folding | ampula

The purpose of the exercise is to model a paper-like structure in GC, using two different methods.

Both methods should generate 3d structures constructed out of identical panels. Using it in real life is significant price-cutting factor, although there is a possibility of massive prototyping of individual elements nowadays.digital folding ampula

The Chinese invented the paper folding art of origami over 1000 years ago, and they endowed it with the aesthetic principies that are at the heart of their culture. As Peter Engel, an American master of the art, says, "the success of a completed figure depends on the creator's eye for form—is it a mere likeness of the original, or does it delve deeper into the form's essential character?" [Engel, 1988]

Engel points out that origami has been taken up in this country by mathematicians rather than artists. He says: "To the mathematician, the beauty oforigami is its simple geometry. Latent in every pristine piece of paper are undis-closed geometric patterns, combinations of angles, and ratios that per-mit the paper to assume interesting and symmetrical shapes."An origami figure always begins with a single square piece of paper. Only folding, with no cutting or pasting, is permitted.

Shape Grammars of Ice-ray Chinese Lattice Designs : haldane liew

Shape Grammars of Ice-ray Chinese Lattice Designs : haldane liew: "Type II designs approach the generation of the ice-rays in a dynamic manner. The rules essentially bisects any existing polygonal shape into two polygonal shapes. Variations for this grammar typically consist of changing the resultant shape from two shapes to many shapes that create a triangular or rectangular shape towards the center."

Type II : parametric shape grammar rules

Rules and Implementation

Rules:

rule 1 : 3 sided polygon -> 3 sided + 4 sided polygon

rule 2 : 4 sided polygon -> 4 sided + 4 sided polygon

AutoDesSys | formZ Features

The variety of 3D forms that can be created with c-meshes is virtually unlimited. Two examples and the control lines from which they were generated are shown below.

The complete range of curved lines (splines), including NURBS, can also be used in a 3D arrangement to produce curved surfaces called controlled meshes or c-meshes. These objects are stored with their control parameters, and can thus be edited later, through interactive graphic procedures, to change their shapes.

The c-meshes can be either surface or solid objects. When solid, their ends can be rounded, or they can be closed to produce a ring-like object.

Architecture and Structural Engineering, textile roofs: "Generation of Cutting Patterns"

Generation of cutting patterns is the process conceptually analogous to the problem of creating maps of the surface of the earth meaning the creation of planar cloth geometries from doubly-curved form-found surfaces. Obviously, whatever technique is used, introducing distortions is an obligatory step in achieving desired results. However, it is common for more distortion than necessary to be applied, and for the distortion to be badly localized. Preferences should be given to the strategies which, as well as providing the highest quality patterns, enable sophisticated monitoring of the distortions due to the enormous variety of patterning situations.

we dont do retro » Blog Archive » Consumer Adoption of Rapid Manufacturing Technologies – Part 3: "Consumer Adoption of Rapid Manufacturing Technologies – Part 3
08Apr08 by Matt Sinclair"

So far I have looked at ways in which rapid manufacturing technologies might become available to consumers, and the reasons why product design for rapid manufacturing is easier than for mass manufacturing. In the final part of this extended post I want to address the only other remaining hurdle to consumers designing and manufacturing their own products: the tools they will use to design with.




Consumer co-design, sometimes called co-creation, is a topic that’s been written about at length by design researchers. At it’s purest it involves the end user, or typical representatives of end users, entering the design process and creating products or services as part of a design team. In practice though, co-design is often little more than an enhanced customer research exercise. End users might be asked about their needs and desires, encouraged to offer suggestions, and even invited to critique proposed solutions. But there is no doubt it is the designers who are expert, and who make the final decision.



As a designer myself, I confess I find it difficult to break free of this mindset – surely my training and experience mean I am able to understand what a market of consumers will want better than an individual consumer themself might? But the point is, what I think will end up being irrelevant if consumers are able to design their own products. Why should a consumer care that I think their product is crass or crude, if it’s exactly what they want, and they’ve made it? At the moment though, I have one trick up my sleeve – I can use CAD, to design a product and to communicate that design to the means of production, in a way that no non-designer can. All the time designers and design engineers can monopolise the expertise needed to create CAD data, consumer created products will not happen
