Is it possible to convert ifc goemetry to mesh format from ifcopenshells python interface directly? Means without the use of subprocess and run the ifcconvert binary.
@bernd it is certainly possible. A very quick and dirty script, although not very robust but for simple geometries seems to work ok, could be something like this:
import ifcopenshell
import ifcopenshell.geom as geom
settings = geom.settings()
settings.set(settings.USE_WORLD_COORDS, True)
f = ifcopenshell.open('/path/to/ifc/file')
for obj in f.by_type('IfcProduct'):
shape = ifcopenshell.geom.create_shape(settings, obj)
geo = shape.geometry
print(geo.verts)
print(geo.edges)
print(geo.faces)
The geo object has a list of vertices and lists of indices for edges and faces.
@bernd if you mean converting IFC to the formats serialised by IfcConvert (e.g. OBJ, DAE, etc), I do not think it is possible yet. However, if the Epic Games application is approved, @aothms would be providing Python access to the SVG serialiser, and maybe that may be the key to the rest.

thanks guys for your suggestions an information.
