Categories, or layers, are created in design applications as a means of categorizing and controlling the display of geometry. The Categories and Models tab contains a list of categories and models contained in the i-model. The tab allows you to turn on, off, or invert, the display of categories or models and search for categories or models by name. The Categories and Models tab is available from the File Browser zone on the middle right.
The Categories tab shows all categories by name and description. Use the search bar to filter the list by typing in the name or description. All displayed categories appear as highlighted in blue along with a checkmark icon. Hidden categories are not selected and have an empty checkbox icon next to them. To change the state of a category, select the row and the category changes to its opposite state.
To quickly change large sets of categories, use the tools in the tool bar to Show All categories, Hide All categories or Invert Selection. These tools work on the current list of categories, which means if the list is filtered using the search bar only those categories are affected.
If you would like to control the display of all items associated to a model, also known as a reference, select the model toggle switch from the tool bar. This changes the list to show all models. Changing the display of these models works just like the category list.
