      </table><br><p class="para_topic"><b class="uiTerm">Global Parameters</b> are parameters that you can set for the entire part. These parameters affect formable sheet metal features such as the flange, inset flange, general flange, bend, and bridge. These parameters also affect the <b class="uiTerm">Flat Pattern</b> application. Once turned on, any formable feature will create with a reference to this global parameter. For example, once you have set up a global bend allowance formula in this dialog box, any flange feature you create will reference the global formula. In addition, if you change your global parameter, any feature created referencing that parameter will be updated to reflect the change.

      <p class="para_topic">The dialog box of a feature that uses global parameters will change when you turn on a global parameter. For example, if you turn on a global bend allowance formula, you will find that the <b class="uiTerm">Flange</b> dialog box no longer has a <b class="uiTerm">Bend Allowance Formula</b> button on it. This is because the <b class="uiTerm">Flange</b> feature will use the bend allowance formula you set up on the <b class="uiTerm">Global Parameters</b> dialog box. By defining these global parameters, you can make the feature dialog boxes quite simple.
      </p>
      <p class="para_topic">On the <b class="uiTerm">Options</b> dialog box of a feature that uses global parameters, you will find option buttons to temporarily disable the global parameters while creating or editing one feature. In other words, if you have created a global bend allowance formula, but want to create one flange using a different formula, you can click on the <b class="uiTerm">Options</b> button on the <b class="uiTerm">Flange</b> dialog box and then turn off the global bend allowance formula button. This one <b class="uiTerm">Flange</b> feature will ignore the global parameter and use the bend allowance formula you set up by clicking on the <b class="uiTerm">Bend Allowance Formula</b> button on the <b class="uiTerm">Flange</b>'s main dialog box. You can also edit a feature and change it to use a global parameter or change it to use its own parameter instead of the global parameter.
      </p>
      <div class="title_division">Global thickness</div>
      <p class="para_division">When you turn on the <b class="uiTerm">Use Global</b> option, you are setting the thickness for the entire part. This means that the feature dialog boxes and application dialog boxes that use a thickness expression or infer their thickness from a selected face or edge will no longer have any thickness widgets. Instead, the feature or application will simply use the thickness you have defined here.
      </p>
      <p class="para_division">You can also tell flange features to always infer their thickness by turning on the <b class="uiTerm">Infer Flange Thickness</b> option.
      </p>
      <div class="title_division">Global radius</div>
      <p class="para_division">When you turn on the <b class="uiTerm">Use Global</b> option, you are setting the radius for the entire part. This means that the feature dialog boxes and application dialog boxes that use a radius expression will no longer have any radius widgets. Instead, the feature or application will simply use the radius you have defined here.
      </p>
      <p class="para_division">You can decide whether the radius value represents an inside or outside radius by simply selecting the appropriate radio button.</p>
