You can use the Element Details section in the Weave tool to change the length of the weave bars, but the Numeric Design Tab will be disabled after colorways have been added in Colorist. The length of the bars can be edited and the thread count can be changed. You can delete out bars and redraw them with the Add Element tool, however you cannot use the Copy to Warp/Weft button as this will break the colorways. Any new color bars should be added to the colorways by selecting the bars and clicking the Add button on the Colorways tab in Colorist. For further assistance please email contact@aquariodesign.com
