      <div class="title_division">Solids Modeling</div>
      <p class="para_division">This general modeling application supports the creation of 2D and 3D wireframe models, swept and revolved bodies, Boolean operations, and basic associative editing. Solids Modeling is the prerequisite for both Features Modeling and Free Form Modeling.</p>
      <div class="title_division">Features Modeling</div>
      <p class="para_division">This feature-based modeling application supports the creation and associative edit of standard design features such as holes, slots, and pockets. It allows you to hollow out solid models and create thin walled objects. A feature can be located relative to any other feature or object and can be instanced to establish associative sets of features. Solids Modeling is a prerequisite for this application.</p>
      <div class="title_division">Free-Form Modeling</div>
      <p class="para_division">This complex-shape modeling application supports the creation of complex surface and solid models. Some of the available techniques are general sweeps along curves; proportionally developed shapes using 1, 2 and 3 rail methods; lofted shapes using standard conic methods; and meshes of points and curves. Solids Modeling is a prerequisite for this application.</p>
      <div class="title_division">Sheet Metal Feature Modeling</div>
      <p class="para_division">This feature-based modeling application supports the creation of sheet metal specific features such as flanges, ribs and cutouts that conform to the shape of their underlying surfaces. These features can then be manipulated in the Sheet Metal Design application to simulate forming and unforming the part. This practice allows you to incorporate design for manufacturing concepts into your parts at design time. Solids Modeling and Sheet Metal Design are prerequisites for this application.</p>
      <div class="title_division">User-Defined Features</div>
      <p class="para_division">This application provides an interactive means to capture and store families of parts for easy retrieval and editing using the concept of a user-defined feature (UDF). It allows you to take an existing associative solid model, created using the standard NX modeling tools, and establish relationships between parameters, define feature variables, set default values, and decide the general form the feature will take when started. Existing UDFs reside in a library that can be accessed by anyone using the Features Modeling application.</p>
