Why is speed important? First of all, if you had a lot of time, you would not be using a CAD, anyway. After all, real fabric will always be better than simulations. Secondly, you want to be free to experiment with CAD. And we do not want you to grow old while waiting for the screen to refresh. And last, but not least - not everybody has the latest Quad-Core Pentium running at 5 GHz. So users with older hardware will appreciate reasonable speed, while those with new toys will enjoy immediate response time.

In ArahWeave, there is no division between the technical and simulation part of the program. ArahWeave always displays the fabric in the main window.

You have a choice of four views of the fabric:

  • Weave:
ArahWeave
  • Integer view (weave colored in warp/weft colors):
ArahWeave
  • Shaded integer view:
ArahWeave
  • Simulation view: there are 7 simulation quality levels - each level takes two times more to calculate, but it is also more precise:
ArahWeave

Obviously, the simulation view quality 7 is also the slowest: 3 seconds for full screen (1600x1200) redraw on Intel Pentium D 3.00 Ghz. Other views are almost immediate.

Simulation quality levels

The following table of simulations shows you the quality difference between various simulation levels. The advantage of having several simulation levels is that you can set the quality to the lowest level, which still gets you a quality simulation, and it this way you can work at highest speed. Or you work at low quality level at initial stages, and switch to high level for final confirmation.

simulation1 45K simulation2 60K simulation3 65K simulation4 60K simulation5 60K simulation6 60K simulation7 60K


It is also worth noting, that the overall color appearance does not change, as you switch from flat color to shaded or simulation view. Some of the competitive products alter the colors significantly if the fabric is shaded.

ArahWeave works with multiple pop-up windows and you can change

    density
    colors
    yarns
    weave
    thread patterns

and immediately look at the changed simulation.

Simulation is the heart of ArahWeave, and does not occupy any additional memory or disk space. It is always re-calculated for screen or for printout at the appropriate density and quality. There is no need to jump from one program to another and there is no difficult climbing through menu structures.
And most important for you - no additional modules to buy.

Internet integration of ArahWeave is easy to demonstrate: This entire web page is made of simulations saved directly from ArahWeave. GIF and JPEG image formats are the basis of Internet, and you can save screen shots, fabric simulations or weaves in those formats. JPEG is more appropriate for simulations, while GIF is works better for weaves. It is easy to send them as e-mail attachment, and most mailers can display images in those formats without the need of any additional programs of plug-ins.

Graphical industry has already embraced the advantages of Internet communication; it is time that weaving industry does the same.

The consumption calculation is even more "Internet ready", since its results are automatically generated in HTML. They are displayed in HTML in ArahWeave, and they can also be saved to disk in this format. Sample of such calculation is shown below, and every weaver will understand what is it all about. We prefer if the weaving mill adapts to this format, since custom adaptation of calculation is an extra cost add-on. For bigger weaving mills with computer departments which write or adapt their own programs, we also provide output in XML, so they can import design data into production database and costing calculations. This DTD file specifies the structure of Arahne's XML file. If you are looking at this page with a browser capable of displaying XML (like for example IE 5.5 or later), you can also look at the sample XML fabric file. You will be able to look at the structure of the file and expand/collapse it by sections.

In any case, you can see the HTML output below. Note that ArahWeave can also automatically generate the fabric simulation and weave, and include it in the HTML file, like on the example below. With some customers, we have even made an additional step - since ArahWeave runs on Linux, we have a free web server (Apache), and all HTML data is saved at such a location, that web server then displays the technical data. Anyone within a company with computer and a web browser is able check the technical details of the fabric, look at the simulation or at the weave. Of course, this all happens behind a firewall, so unauthorised persons can not access this data. Such a setup works nicely across platforms - Windows, Linux or Mac. Since weaving mills develop several thousand designs each year, we have even developed a web searching interface in Perl, so that they can easily find their the desired fabric design.

printed fabric simulation

printed weave

The weave is the fundamental property of the fabric, it specifies how do the weft threads interlace with warp to make the fabric. Experienced weavers are able to look a the weave in black and white and immediately see what is going on. But everyone can use a little help, and ArahWeave allows you to look at the weave in different ways.

The Weave editor in ArahWeave has five different view modes:

 

Weave
Yarn colors
Jacquard colors
Decomposed colors
Regulator

 

The Weave view is the default mode of weave editor. Black point indicates warp (vertical thread) above weft (horizontal thread), while white point means that weft goes above warp.
weave editor

Sometimes it is better to view the weave in colors. If you enable the Yarn colors view mode, the weave will be drawn in warp and weft colors. Some simple programs call this "simulation". You can even buy a a book, which will teach you how to do this in PhotoShop with 10 layers and 200 mouse clicks ;-)
weave editor

The Jacquard color view mode displays a jacquard image, from which the weave was developed, over the weave. Use it, when you want to precisely see the transition from one weave effect to another in the jacquard weave.
weave editor

For reference, here is the same fabric in the simulation view in the main ArahWeave's window.
weave editor

Another helper with complicated weaves is the Regulator view. It shows wefts with regulator (black point on the rightmost edge) in colors (yellow for weft up, and blue for weft down). It is much easier to distinguish between ground and extra wefts, especially if you want to draw some regulator controls manually (with mouse).
weave editor

The last view mode is the great tool for composing multilayer weaves, especially for placing the stitching points between the fabric layers. Each layer has different color pair for presenting warp and weft points, which enables faster and more accurate placement of stitching points.
Can you notice points between first warp and second weft?
weave editor

And here?
weave editor

In addition to that, you have two extra toggle buttons in the View menu.

 

Dobby view just enables you to switch dobby card on or off, since sometimes you do not wish to be disturbed by it.

Cross section shows you the the warp and weft cross section on top and right of the weave editor, as shown in the tutorial: Construction of multiple Layers.

ArahWeave software for weaving has a special function for constructing multiple layer (double) weaves; you specify basic weave for each warp against each weft and the program automatically constructs the composite weave. This function is available as a special popup window on in weave editor, named Edit decomposed. If you position your windows properly, you can view fabric simulation, normal weave editor and decomposed editor, all at the same time. And you can also enable the display of horizontal and vertical cross section. Cross section is interactive - it shows you the cut at the current mouse position. Even more - you can draw with mouse and change position of threads, and weave will be modified accordingly.

In the picture below, you have a weave with 1 warp and 3 wefts, with 5-satin on top and 5-satin on back for attachment of second weft, and 10-satin for attachment of third weft. But as a true weaver, you know all this...


multilayered weaves in ArahWeave

The mysterious double interchanging plain weave from density explanation is much more understandable if we view it in the Edit Decomposed window.


double weave in ArahWeave

With the right tools, everything suddenly becomes easy and logical.


double weave decomposed

You can edit even more complicated composed weaves, for instance those with different densities of top and bottom fabrics.

Do not be scared away by the following picture - many experienced weavers would also find it difficult. We have a special double fabric with uneven top and bottom density, plus an extra weft which is hidden in the middle and just links the two fabrics together. The warp layout is simple: 112 (we can write it also as 2a1b)- this means that first two warp ends go in first block, and third warp ends goes into second block. In this way we have two times higher density in warp. Weft is similar, just that we need to repeat the layout until the end, so we can add the third block for extra hidden thread: 8(2a1b)1c. Yes, it is just copy of weft repeat pattern. We enter elongated twill for the top fabric, and regular 2/2 twill for back fabric. The middle weft thread (shown in red) has just two points which link it to the top and to the bottom fabric. We also add a regulator (stop motion) on the middle weft thread, so that it does not disturb the weft density of the fabric. Note that the fabric simulation in the lower left angle does not show any threads from the back (grey) or middle (red), since they are completely covered by the top fabric (black weft and dark blue warp).
double weave in ArahWeave

We have no ambitions to teach you weaving here - if you do not understand it, than you probably do not need this. But if you do, you see that it that design of complex weaves with ArahWeave is very easy. (If you know what you are doing... ;-)

Weave editor handles both jacquard and dobby weaves. If the weave can be woven on dobby, it also shows tie-up and card; otherwise this information is hidden.

   

Maximal weave size 65520x65520 - really, it is not a typing error ;-) If in doubt, download the demo and try it.

   

Maximal number of shafts is 50 (nobody has that many, but can be useful for editing)

   

Weave editor grid is fully customizable, both as grid dimensions in x an y direction, as the line thickening

   

You can enter denting (sley) and regulator (warp beam let-off) and view it in fabric simulation. Empty dents are also supported! Regulator (and denting) can be entered in numerical way or drawn on the side (or top) of the weave.

   

Operations like move up, down, left right, negate clear ... work on selection or full weave. Copy/extend selection to larger area. You can load other weaves into selection - weave patchwork can be drawn in a matter of seconds.

   

Program can control threads reversal: if two (or more) threads are in the same dent with very similar weave, the program will warn you that there is danger of threads reversal.

   

In pattern draft, the lines are drawn (or printed) in gray to permit easy counting of both black and white squares

   

Warp and weft pattern are drawn and printed on the side of the weave, to avoid errors in drafting

   

"left" and "right" dobby cards are supported through program customization

   

Export the dobby card to 3.5" floppy in electronic dobby format Stäubli 1858III, Dornier DoTech and DoStyle format

   

Export the drafting and drawing-in information for VEGA drawing in machines in .VIF format. Empty dents and skipped drafts are supported.

   

Weave can be displayed in standard black (warp) & white (weft) notation, or in current warp/weft colors

   

You can insert or delete any number of warp or weft threads anywhere in the weave

   

It is also possible to edit the weave by clicking directly on fabric simulation.

   

If you develop the weaves for the dobby loom, you will appreciate that you can save or load individual weave elements, like just the card or just the drafting. In this way, you can have the fixed warp and drafting and just load different cards. If you find something interesting, you have created a new design at almost zero cost.

And if you are looking for new weave ideas, we have a library of 10039 (ten thousand thirtynine!) weaves, sold separately as an option. You can browse them with incredible ease. Even the weaves which you will create during your work with ArahWeave will be automatically browsable. So if you know how your weave looks, you will be able to find it, even if you forget its filename.

Furthermore, you can sort them by:

  • name
  • number of shafts
  • warp float length
  • weft float length
  • date
  • size
  • effect (relative % of warp points)
  • warp consumption
  • weft consumption

You can view all these weaves in colors of warp/weft to discover interesting raye effects. ArahWeave is a nice program - it allows you to resize the window and it will display more data. The weave display grid is customizable. And to load a weave just double click it. What could be simpler than this?

But it doesn't end here. If you enable Color button, you can browse the weaves in actual warp/weft colors and view the simulations in real density. You will discover many new possibilities. Using the same warp, you can make many new designs with almost zero cost!

It goes without saying, that ArahWeave will optimize the number of shafts or redraw draing-in to desired number of shafts. But what if the number of weave shafts is bigger than the number of shafts on your loom? We have a cure for this, too. Mergers of companies are very fashionable nowadays, and you can use it on your shafts. ArahWeave will find the two most similar shafts, and identify the differences. It is then up to you to remove the differences, so that they can be merged.

merging shafts with ArahWeave

You can also print out the complete weave, including selvedges. Printout is customizable, and you can switch off individual elements which you do not need.

To make our software easy and natural for both experienced textile designers, as creative designers not too familiar with weaving, we provide two ways of entering warp and weft pattern. Creative designers will click on the the yarn with mouse and draw the pattern directly in the fabric simulation. An experienced designer will prefer to write the warp/weft pattern in numerical way since he/she has precise ideas about what he/she wants to do and will not want to lose time by accurate mouse clicking (although zoom is available).

   

Up to 25 different yarns in warp and 25 in weft can be used simultaneously.

   

You can easily design patterns with up to 65520 threads.

   

Besides drawing warp/weft pattern with mouse, you can also insert or delete threads anywhere in the pattern with mouse.

   

If the user is drawing the warp/weft pattern with mouse, the program automatically rewrites the numerical warp/weft pattern.

If the warp/weft is written in numerical way, it can be written as number of threads (2A 4B 2A 6C) or as length in millimeters (0.5A 1B 0.5A 1.5C) or sixteenths of inch. Conversion from number of threads to millimeters (inch/16) and vice versa is automatic.

Two types of parenthesis are supported for entry of repeating patterns: 2a 10(1b 2c) - repeat 1b 2c 10 times; and 2a 10[1b 2c] - repeat 1b 2c until you use 10 threads. Nesting of parenthesis is allowed.

   

Conversion of fabric from one density to another, and keeping the same repeat size is automatic

Generation of a square design (e.g. tartan) with different density in warp and in weft is automatic

It is possible to move warp/weft pattern by 1 or 8 threads in any direction, or to mirror it

Fringe option permits view and print out edge of just warp (bottom) and weft (left) besides design, just like in real fabric. It looks like this.

Sort option will rewrite the pattern so that it starts with yarn A, followed by B, etc., as this is required by production department of many mills.

A special function enables you to split (or merge) weft across several weft selectors.

Support for design of fabrics with two warp beams

Double weft insertion support

Loading, graphical browsing and saving warp or weft patterns

Tools: editing decomposed, the Pattern generator, resizing warp/weft pattern, remapping yarns

 

This is how the warp and weft pattern editor looks:

Centering of the the warp or weft pattern according to total number of threads in the fabric width, or blanket width. You can center it manually or automatically.

The Editing decomposed function opens a whole new world to the "complicated" warp or weft patterns. It enables to divide the pattern by different criteria (custom, denting, two warp), which drastically reduced the time needed for writing a new pattern, or changing already created pattern.
Double face fabrics? No problem.
The following picture shows double layer weave in the Weave editor. We want to have one plaid fabric with twill weave on the top, and a different one on the back.
decomposed editing of weave with ArahWeave

So, how to write a pattern for both sides, face and back? Open the Edit decomposed window from the Tools menu of the Edit warp and weft pattern window. You need to write pattern for the face fabric, and then pattern for the back fabric; both are quite simple. Program will automatically combine both patterns into one warp pattern. Of course, you also need to do this for the weft.
