3D print - Teknologi

3D print - Teknologi: "Ny teknologi gør det muligt at præsentere arkitekters og ingeniørers ideer i form af 3D-modeller.

Rambølls nyindkøbte 3D-printer fremstiller gipsmodeller med udgangspunkt i 3D-modeller udarbejdet i et CAD-system. Den håndterer både farver og materialer, som følger med modellen.

Materialet er gips, som bliver limet sammen med farvet lim, og det er hemmeligheden bagved de billige priser. Printeren læser CAD-modellen lag for lag og giver mulighed for at fremstille de mest komplicerede dobbeltkrumme flader, uden problemer.

Har du modeller, som du gerne vil have printet, kan du sende dem til vurdering og få oplyst pris og leveringstid. Vejledende priser finder du her på siden. Du kan sende din model til Thomas Lundsgaard.

Har du store modeller, som ikke kan sendes pr. mail, kan du bruge vores ProjectWEB til overførsel af filerne.

Creating paper models

Creating paper models: "Creating paper models EDIT: I am working on an automated script for this purpose. You may want to try it - it could save you a hour of work. Link

Blender comes with a script called Unfold. It can easily turn mesh into a flat net, without deforming any faces. What is it good for?

If you use some more tricks around and are not afraid of mat-knife, you can have all your blends staying in front of you on the table. All you need is a printer, a good glue, two hands and blender (blender is almighty!).

I've made three models yet - the Suzanne (topic here), post appocalyptic tank (topic here) (Alltaken made that model, but he released it under CC here) and a spaceship, the topic is here. It is a simple spaceship without any interesting ideas, because I made it mainly for needs of this tutorial.
You can get the .blend file here."

UNFOLD3D Generation 6 User Manual

UNFOLD3D Generation 6 User Manual: "3.1 - Modeling Rules
Unfold3D requires the input mesh to respect a certain number of modeling rules. These rules are generally respected as rules of general modeling hygiene, but they become compulsory to apply Unfold3D's mathematical algorithms:

Rule 1: no edge with 3+ neighboring polygons (see figure). All edges must belong to at most two polygons.

Rule 2: no butterfly point (see figure). A vertice cannot have more than two border edges (ie: edges with only one neighboring polygon) connected to it.

Rule 3: the imported file must comply with OBJ standards, and not use the the ' relative vertex numbering ' mode.

Note that these rules do not limit the possibilities of modeling:
Unfold3D has no problem dealing with holes in the mesh;
the modeling rules are written for triangles, but Unfold3D is perfectly fit to deal with quads or n-gons - Unfold3D will triangulate the mesh anyway, and try to avoid as much as possible the forbidden cases.

Note that non-convex n-gons may cause problems though:"

Dickson Sunbrella - Sunworker M1: "HIGH-PERFORMANCE THERMAL BARRIER
Thanks to its highly regular, perforated micro-structure, the fabric acts as a genuine heat filter. It repels up to 92% of the warmth of the sun’s rays, thus avoiding any greenhouse effect and preventing buildings from overheating in summer. In winter, the process is reversed, thus maintaining heat within the building."

MPanel Software

MPanel Software: "Tensile fabric structure designers can now have a complete set of tools, running in industry standard CAD software, AutoCAD or Rhinoceros®.

MPanel is our flagship product and works inside AutoCAD . MPanel software runs in many older versions of AutoCAD, releases 14 through to 2010, so you don't have to buy the latest AutoCAD version to use our MPanel products!

MPanel-R is the identical product to, MPanel, except that it works as an add on toolbar inside Rhino 4.

MPanel and MPanel-R, incorporate a set of design tools into a user friendly interface to assist tensile fabric structure designers. MPanel works inside AutoCAD or Rhino as a floating tool bar, and manipulates your CAD drawing from the initial relaxation of a mesh to the final production panels for you to send to your plotter or cutter.

MPanel was developed to assist tensile fabric structure designers, but works equally well on other projects, such as tents, awnings, exhibition stands, and inflatable structures.From this....
to this.....in just a few clicksThe MPanel add-on toolbar works with AutoCAD and Rhino, so there is no need to learn a complete new CAD environment. We let you leverage your CAD skills, so you are up and running with MPanel in a very short time"

form z vs rhino - Architosh Forums - Mac CAD and 3D Discussion

form z vs rhino - Architosh Forums - Mac CAD and 3D Discussion: "Originally Posted by frem001
It depends what you are planning on doing. I know that Rhino has some powerful scripts that allow you to flatten and label complex 3d shapes so it can be taken to a laser cutter and then assembled by hand. I haven't seen this in formz.

Both Rhino and formZ have the ability to flatten/unfold objects.

Rhino's buildt unfolding features are comparatively primitive, unless you spend $900 on a plug-on called Expander.

A suggestion would be to have a look at TouchCAD, which is built around the combination of 3D modeling and unfolding / fattenting features. It is the only true five-dimensional program, where all 3D panels are dynamically and parametrically linked to the unfolded patterns. These features integrate the production preparation and optimizing the use of material into the design process and generates production ready results very quickly. TouchCAD comes with a very extensive set of unfolding settings, such as split resolution, direction, overlaps/seam allowances, automatic coordinates, panel and point numbering, alignment marks, stretch unfold calculations, image unfolding etc. On the 3D side TouchCAD comes with a full set of modern push-pull tools, which works from any view and direction, dynamic cross sectioning which is absolute must-have for accurate shape control, etc. www.touchcad.com"

Finite element method - Wikipedia, the free encyclopedia

Delaunay triangulation - Wikipedia, the free encyclopedia

Delaunay triangulation - Wikipedia, the free encyclopedia: "In mathematics, and computational geometry, a Delaunay triangulation for a set P of points in the plane is a triangulation DT(P) such that no point in P is inside the circumcircle of any triangle in DT(P).

Delaunay triangulations maximize the minimum angle of all the angles of the triangles in the triangulation; they tend to avoid skinny triangles. The triangulation was invented by Boris Delaunay in 1934[1].


For a set of points on the same line there is no Delaunay triangulation (in fact, the notion of triangulation is undefined for this case). For four points on the same circle (e.g., the vertices of a rectangle) the Delaunay triangulation is not unique: the two possible triangulations that split the quadrangle into two triangles satisfy the 'Delaunay condition', i.e., the requirement that the circumcircles of all triangles have empty interiors.
By considering circumscribed spheres, the notion of Delaunay triangulation extends to three and higher dimensions. Generalizations are possible to metrics other than Euclidean. However in these cases a Delaunay triangulation is not guaranteed to exist or be unique."

Walking in a Triangulation - VoroWiki

Walking in a Triangulation - VoroWiki: "Given the Delaunay triangulation (DT) of a set S of n points and a query point p, the point location problem consists of determining inside which triangle of lies p.

This is a necessary operation for the incremental constructing of a DT, for deleting a vertex from it, and also for different spatial analysis operations.

The method described here is called walking in a triangulation, and does not need any pre-processing or any additional data structures.

The adjacency relationships between the simplices in a DT are used to perform the point location. The algorithm was described in the earliest papers about the construction of the DT in two dimensions (Gold et al., 1977)[1]; Green and Sibson, 1978[2]): in a DT, starting from a triangle τ, we move to one of the neighbours of τ (τ has 3 neighbours; we choose one neighbour such that the query point p and τ are on each side of the triangle shared by τ and its neighbour) until there is no such neighbour, then the triangle containing p is τ. The algorithm is illustrated on the right."

Voronoi Diagrams and Delaunay Triangulation

Voronoi Diagrams and Delaunay Triangulation: "A Voronoi diagram is a geometric structure that represents proximity information about a set of points or objects. Given a set of sites or objects, the plane is partitioned by assigning to each point its nearest site. The points whose nearest site are not unique, form the Voronoi diagram. That is, the points on the Voronoi diagram are equidistant to two or more sites."
