Suppose that the IFC to be modified is the result of the federation of three models (structural, architectural, plant engineering) produced with different BIM authoring.
The IFC file is the 'digital twin' of an existing building that has undergone changes over time (e.g. boiler replacement and demolition of a partition).
Normally, in order to update the model and make it conform to the state of the art, you would have to edit the 3 models individually (using 3 different BIM authoring!) and federate again.
With usBIM.editor you can work directly on the federated model and make the necessary changes, optimising costs and working time.
To make changes to the IFC file, follow these simple steps:
- open usBIM.editor
- click on "New" and choose your "IFC document"
- select the IFC file to work on
- from the "Drawing" section, select the drop-down menu and choose the "3D Model" option
- in the Properties window, under Features, then Model, open the BIM object library and choose the desired model (in this case, we’ll insert a boiler with the same characteristics as the existing model)
- position the object at a certain point
- choose the "IFC editor" environment
- delete unwanted elements (in this case the old boiler and the partition wall) use the "Delete" key on the keyboard
- once your changes are completed, click the "Export to IFC" button to export your modified file
