IFC object type, IFC object subtype

IFC object type and IFC object subtype are important for BIM experts. In earlier versions, 40 IFC object types were available for selection. This selection was fixed and could not be changed. Now the most commonly used 21 IFC elements are predefined. Using a dropdown list, you can add as many IFC elements as you need to this selection.

You can use IFC object subtypes independently of IFC object types. A lot of IFC classes have subtypes so that you can specify the classes more precisely. In most cases, the program assigns the subtype automatically during export. Using subtypes, you can specify the objects more precisely. This is particularly useful in conjunction with IFC object types.

Using IFC object types and IFC object subtypes, you can transfer meaningful and detailed IFC files to your planning partners.

You can find detailed information on IFC object types and IFC object subtypes in the Allplan BIM compendium, which you can download as a PDF file from the Allplan home page.
