IfcConvert F.A.Q.
Q. How can I output geometry and spaces?
A. IfcConvert excludes spaces and opening elements by default. --include --entities IfcSpace
means "include only spaces". In order to get regular geometry + spaces, use --exclude --entities IfcOpeningElement
.
Q. I'm trying to output SVG (2D floor plan), but the conversion fails
A. SVG output includes only spaces by default so your IFC file is probably missing them. Use e.g. --include --entities IfcWall
to generate output with walls.
Q. Elements are missing from my SVG (2D floor plan) output
A. In addition to the answer above: for SVG output, products are sliced at a horizontal plane 1 meter above the bottom of their bounding box. Only the intersection with this plane is written to the file. If the geometry for a product is less then 1 meter tall no geometry is recorded for this product.
