Understanding Threads and Width or Length in the Assembly Tree
When designing the Assembly Tree, thread counts and generated widths/lengths are calculated automatically. Warp uses ends per inch and Weft uses picks per inch as defined in the Project Information: Project Information-Planning-Setup
In the following example showing a Weft Section Assembly Tree, Group Example A is collapsed. The heading shows 38 Threads (picks) with a Length of 1.9 inches (the draft has 20 picks per inch).
The next Group Example B is repeated 2 times and is made up from the following sections and sub-groups:
Section 1 - 14 threads
Group B1 - 25 threads repeated twice for a total of 50 picks
Section 1 - 14 threads
The above adds up to 78 threads (picks). The Group Example B is repeated twice, meaning that there are a total of 156 picks defined by that area in the Assembly Tree accounting for 7.8" woven length.
When designing, it's easy to change the repeats at any level and not only see the impact.
