      <div class="title_division">Wrap methods</div>
      <p class="para_division">The lower window of the <b class="uiTerm">Assign Stock</b> dialog box presents additional options if the type of overstock being assigned is <b class="uiTerm">Wrapped</b> (such as tape).
      </p>
      <p class="para_division">If the overstock type is <b class="uiTerm">Wrapped</b>, the first option is <b class="uiTerm">Wrap Type</b>. The options are <b class="uiTerm">Spot</b>, <b class="uiTerm">Overlap Spiral</b> and <b class="uiTerm">Striped Spiral</b>.
      </p>
      <p class="para_division">If the <b class="uiTerm">Wrap Type</b> is <b class="uiTerm">Spot</b>, you may specify Number of Wraps. This is the number of times the overstock wraps around directly on top of itself (usually two or three times). You can use the number of wraps to determine the length of the overstock used (along with the covered diameter and the overstock thickness).
      </p>
      <p class="para_division">If the <b class="uiTerm">Wrap Type</b> is <b class="uiTerm">Overlap Spiral</b>, then you may enter the <b class="uiTerm">Percentage Ovrlap</b> (between 0 and 100). A 50% overlap implies that the overstock covers half of its width with each wrap and leaves half uncovered. A 25% overlap means that is covers just a quarter of the width and three quarters is not covered.
      </p>
      <p class="para_division">If the <b class="uiTerm">Wrap Type</b> is <b class="uiTerm">Striped Spiral</b>, the second entry specifies <b class="uiTerm">Gap Distance</b>. The overstock does not overlap, but leaves a gap between each wrap. The width of the gap between wraps is the gap distance. Note: Use this for overstock length calculation only, and is not reflected in the solid model generated to represent the overstock.

      <p class="para_division">The difference between the manufactured (real) appearance and the displayed appearance for the different wrap methods appears in the image below.</p>

      <div class="title_division">Wrapped overstock length calculations (information only)</div>
      <p class="para_division">Special calculations determine the length of wrapped overstock (spot, overlap spiral and striped spiral). This functionality is set up as a plug&ndash;in to allow custom programming of these calculations with a default algorithm and sample plug&ndash;in provided. For wrapped overstock, the default algorithm computes the length as follows:</p>
      <ul>
         <li>
            <p class="para_item">If the additive is spot wrap, L = C * T</p>
