How do I convert an IFC file to STL?

Upload your IFC file, set tessellation options such as chord and angle tolerance, then click Convert. The tool exports an STL mesh of the building geometry. BIM attributes and object names are not carried over.

Why should I convert IFC to STL?

STL is the universal format for 3D printing and is supported by most CAD and slicing tools, while IFC is a BIM schema for architecture and construction. Converting to STL allows you to 3D-print building components, import into generic CAD software, or simplify the model for visualization.

How does the conversion handle IFC geometry and metadata?

IFC geometry is tessellated into triangles, so curved surfaces become faceted based on your tolerance settings. STL stores only geometry, so colors, layers, materials, and BIM metadata are discarded. The resulting mesh preserves the shape within the specified tolerance, but no semantic data is retained.

IFC-TO-STL

Convert IFC building models to STL meshes for 3D printing. Adjustable tessellation preserves exact geometry while dropping BIM semantics.
