Multiple model categories can be assigned to a single model class and a single asset class. However there is a one to one mapping between a model sub category and a CI class.</p> <div class="p"><div class="fig fignone" id="model-hierarchy__fig_esk_x53_tsb"> <img class="image" id="model-hierarchy__image_u52_z53_tsb" src="../image/modelcategory.png" alt="Model category" /> </div> </div> <div class="p">40 base model categories are available for you to choose from. The top tier model categories are as follows: <ul class="ul" id="model-hierarchy__ul_ltq_gsw_fsb"><li class="li">Enterprise</li><li class="li">Construction</li><li class="li">Medical</li><li class="li">Transportation</li><li class="li">Industrial</li><li class="li">Facility</li><li class="li">Retail</li><li class="li">Tactical equipment</li><li class="li">Wearable</li></ul> </div> <p class="p">You can also create your own model categories. However you can't create sub categories within the top tier model categories. For example, if you do not wish to use any of the sub categories provided in the Medical model category, you can use the general Medical-other sub category instead of creating a new sub category.</p> </div> </body></html></div>
