# Section Assembly Quick Summary

The **Section Assembly** options are located on the **Design** menu, as shown above. The **Section Marker** is a drawing tool used to define sections of a draft. Selecting **Section Assembly** opens a panel that provides controls for grouping and repeating these sections to generate a new weaving draft. Both **warp** and **weft** sections can be marked. Once marked, sections may be grouped and repeated in any order. In addition, groups and individual sections can be copied and nested, allowing for rapid prototyping and easy resizing of drafts. It's recommended that *Ends Per Inch (EPI)* and *Picks Per Inch (PPI), or Ends and Picks per Centimeter, a*re updated in **Project Information** so that you can see the widths and lengths that the section definitions are defining. If you forget to update the SETT before starting, simply change the Sett, then use the Refresh button on the Section Assembly panels for warp and weft to recalculate. When you are ready to generate a draft from the section assembly instructions, click the Generate Button with the Checkmark button; it's available on each tab, so it doesn't matter where you click it. TempoWeave will create a new WIF file based on your Section Assembly selections. You may close the generated WIF to make further adjustments and regenerate it, or save it if the result meets your needs. When working with Section Assembly, it is recommended that you save both the file containing the marked sections and the generated WIF. It is common practice to keep multiple versions of Section Assembly drafts (those with section markers and grouping instructions) so you can easily reproduce a generated draft or make future modifications. The following documents explain how to use Section Assembly in more detail.
