Converting a 3D model into an IFC format

Converting a 3D model into an IFC format

Here is a practical example showing how easy it is to convert a 3D model made with SketchUp into an IFC format

How to convert a 3D file made with sketchup (or another BIM software) into an IFC file? In this article I’ll explain how to use a free IFC viewer!

A BIM methodology typically integrates all the useful information into a single model during the design stage, combining architectural, structural, plant and technical installation system aspects.

The BIM methodology is, in fact, based on the collaboration between different figures involved in different phases of an asset’s life cycle.

The information exchange takes place thanks to the IFC: a special open data and non-proprietary format that enables collaboration between the various figures involved in the construction process. Therefore facilitating the information exchange, without any risk of data loss.

The IFC file then becomes, a means of communication between professionals using different software..

How to convert a 3D model into IFC using a software

Using a free IFC viewer you have numerous features, including the ability to convert and export to IFC format, files such as: AutoCAD® (.dwg) 3D model, SketchUp (.skp), 3D Studio Max® (.3ds) and many others.
In this short example we will see how simple and immediate it is to convert a SketchUp object (.skp) into an IFC format using usBIM.viewer+.

  • From the usBIM.viewer + menu create a new document and upload a 3D model.



  • Name the entity, indicate the model’s unit of measurement and then assign it to the relevant IFC class.



  • Start the conversion and insert the object into the model


We have seen how easy it is to convert a sketchUp file into IFC format with a few simple steps.

Moreover, thanks to usBIM.viewer+ you can export in 2x3IFC file format. Having therefore the possibility to add properties to the IFC files. Thus enriching existing information with further technical, commercial, structural, technical system installation, estimating and many other data. Particularly without the need of a BIM authoring software.
