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:

• Integer view (weave colored in warp/weft colors):

• Shaded integer view:

• Simulation view: there are 7 simulation quality levels - each level takes two times more to calculate, but it is also more precise:

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.

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

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.
