IFC-compliant creation of model in Allplan

In accordance with the specifications defined by buildingSMART international, there are a number of essential mandatory planning rules to be observed when creating an IFC-compliant business model.

The basic rule is that only objects and elements modeled in 3D can be part of the IFC-compliant building model: Texts, line drawings, dimensions and so on are not therefore included. The same applies to 3D lines and surfaces, which are not planning objects in terms of IFC.

Consequently, if you want to add information to a component or object, you must include these pieces of information in the geometry of the component or object. As an alternative, you can also define an (additional) attribute and assign it to the component or object. This also applies to values and data you receive from other project participants, for example, the structural engineer.

In addition, the data structure within the model and thus within the whole project must be in compliance with IFC specifications. To achieve this, you must use a building structure in Allplan. In addition, you can only use specific structural levels within this building structure.

Check these rules time and again, doing so at regular intervals while you create and edit your models.

• All elements and components of the building model in 3D are created using the appropriate Allplan tools (if appropriate tools are available).
• Define any details and values of the components and objects together with their geometry or attach them as attributes (parameters, properties) to the components and objects.
• Use a BIM-compliant building structure to structure the data. Place the data of the model in drawing files, which you assign to the required structural levels within the building structure.
