Description
Describe the bug 📝
This may not be a bug and more an issue of understanding how to accomplish exporting a BufferGeometry. In my understanding I should be able to create a BufferGeometry, add it to a ClayObject and than add that to a site. Exporting this should result in an IFC that has that BufferGeometry. This is not the case:
const model = new Model();
await model.init();
const project = new Project(model);
const site = new Site(model, project);
/* add pyramid */
var geometry = new THREE.BufferGeometry();
const vertices = new Float32Array([
// Base square (two triangles)
-1, 0, -1, 1, 0, -1, 1, 0, 1, // First triangle of the base
-1, 0, -1, 1, 0, 1, -1, 0, 1, // Second triangle of the base
// Four triangles for the sides
-1, 0, -1, 1, 0, -1, 0, 1.5, 0, // Front face
1, 0, -1, 1, 0, 1, 0, 1.5, 0, // Right face
1, 0, 1, -1, 0, 1, 0, 1.5, 0, // Back face
-1, 0, 1, -1, 0, -1, 0, 1.5, 0, // Left face
]);
geometry.setAttribute('position', new THREE.BufferAttribute(vertices, 3));
const furnitureType = new SimpleFurnitureType(model);
furnitureType.body.baseGeometry = geometry;
furnitureType.update(true);
const furniture = furnitureType.addInstance();
site.children.add(furniture.attributes.expressID);
/* write to file */
fs.writeFileSync('test3.ifc', model.ifcAPI.SaveModel(model.modelID));
console.log('test3.ifc successfully created!');
I've written something very close to this using ifcopenshell, although it needed more relationships. It is not clear to me how I would add those within Clay. Is this the wrong approach?
I do have the same issue when I try to do it with the Demo (https://thatopen.github.io/engine_web-ifc/demo/)
