      <div class="title_division">Geometry Quality</div>
      <p class="para_division">You should carefully inspect the product model before starting a Mold Wizard project. Producing a good quality mold design requires a good quality product model. Before beginning your mold design project, run Examine Geometry on the product model to locate any problem areas and then correct them. The Examine Geometry function is found under the Analysis menu. </p>
      <p class="para_division">You can also use the Heal Geometry function to improve the quality of imported models. This function is under the NX File &rarr; Export &rarr; Heal Geometry menu.</p>
      <div class="title_division">Solid or Surface Model</div>
      <p class="para_division">The Mold Wizard parting process can use either a solid model or a sewn set of surfaces that do not form a solid. When possible, use a solid product model because it will produce solid cavity and core models. Solid cavity and core models provide some advantages in drafting and CAM processing. Therefore, in most cases, it's worth the additional effort to correct product models with geometry problems and sew them into a solid.</p>
      <div class="title_division">Moldability</div>
      <p class="para_division">Some product models do not have correct draft (mold taper) and/or designs for efficient construction of mold shut-off areas. You should correct the product model to have exactly the geometry that you want in the finished cavity and core. Beginning with a corrected product makes the parting process easier and gives you ready-to-manufacture cavities and cores. A final reason to correct the product model is that adding taper to the cavity, core, or electrodes as an afterthought is far more likely to produce errors.</p>
      <div class="title_division">Molded Part Validation (MPV)</div>
      <p class="para_division">MPV is a useful tool for examining product models and is found under Analysis &rarr; Molded Part Validation. MPV can be used without initializing a Mold Wizard project. To examine a product model using MPV, you open the product model, then select the Analysis menu and click Molded Part Validation.</p>
