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.

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 ;-)

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.

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

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).

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?

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.
