Modify pattern

Since the Draw patterns window draws all the patterns, we can do two equivalent actions: Press the left mouse button on any of the patterns. Write the number (or click side scroll arrows) of the pattern that we wish to modify in the top left box of the screen. We have many values in the left margin . We are going to comment on them: General data Number Each pattern has a …Read More

Patterning between two geodesic

This menu allows you to create a pattern using only two geodesic lines. Therefore, it is a very fast method to generate patterns, but is only valid for those cases in which the perimeter of the membrane does not include other points, because this method does not consider them. If we observe the figure on the left you can see how the patterns located between the geodetic 4-3, 3-2, 1-5, and …Read More

Patterning by perimeter

By defining perimeter of the pattern, we can generate a pattern more comfortably than the “by triangles” method. However, once the pattern is created, it is very important to check the triangularization that WinTess3 proposes in order to avoid incorrect patterns due to an error in data entry or malfunction of the program when it comes to generating these triangles. To define a pattern we start with the furthest point …Read More

Patterning by triangles

This phase involves of drawing triangles on the membrane, using only points on the perimeter and the geodesic lines. WinTess3 supports using any point on the mesh, but is completely inadvisable to do this, because that will possibly lead to erroneous or distorted patterns. It should take into account that these triangles, folded and placed in a plane next to each other, form the pattern.  So it is absolutely necessary the …Read More

Process

Before we begin patterning of a structure we must take various aspects into account: State of the program We have already mentioned that WinTess3 is a program “all-in-one” type suite with very clear three states of the program. In order to make a pattern, it is necessary that the program is in the state of Patterning, so we need to update using the drop-down from top toolbar. If we open a file saved previously, WinTess3 remembers …Read More

Program Modules

The tensile architecture, as any other architecture, passes through a few different design phases. However, these phases tends to clearly differentiate three very different tasks or states: Form finding Calculation of the structure Patterning and detailing It is for this reason that many computer programs that are used in the field of architecture tensioned only serve for any of these tasks. Some of them, such as WinTess3, serve for all three. …Read More

Pattern Types

Patterning is one of the basic tasks of designing tensile membrane structures. It is also one of three modules of WinTess software shown in top bar. The usual way to transform a warped curved surface in flat strips (patterns) is doing by triangulation. It is the easiest and most used way. In another post in this blog (cross compensation) we already discussed triangulation of patterns. Given that membrane is delivered …Read More

Multi-geodesic lines (1)

The most common method of creating patterns on a membrane involves drawing geodesic lines on the membrane.  Justification of the layout of the geodesic lines is beyond the scope of this text . Although the geodesic lines can be drawn freely to form patterns of any shape and position, it is common that the route of the geodesic lines follow some models determined: Geodesic lines more or less parallel to …Read More

Cross compensation

The common way of patterning of a tensile membrane is to break down to triangles which are always flat (see the below figure). This series of adjacent triangles is called as pattern. It is obvious that the triangles are defined by the sides, and these are straight segments while the membrane surface is curved (almost always double curvature). Therefore triangles are always smaller than the area representing membrane. The program …Read More

Modifying patterns

Sometimes we find a membrane to which you have applied a certain design. Everything has been done successfully, but at some point we would slightly change the pattern. The reasons can be different: the pattern does not fit into the width of the fabric by a little while you have enough membrane to compensate on the next pattern. we wish to avoid the seam between patterns pass through a given …Read More
