Bounding box in global coordinate

[ovaisa]

I want to get element bounding box in global coordinate system. It seems element BBoxLow, BBoxHigh are in local coordinates. I can get origin, yaw, pitch and roll for the element - can someone point me to code that shows how to create a transformation matrix or a function to convert from local to global coordinates.

Thank you!

The bounding box, origin, and orientation define the element's Placement.
Both Placement3d and Placement2d have a calculateRange method that will give you the bounding box in world coordinates.
They can also supply a Transform to world coordinates.

Thank you Paul, it worked! Much appreciate your support.

For benefit of others might need this in future, here is my code snippet

// Reference: frontend-sample-showcase>clash-review-sample>ClashReviewApp.tsx => calcClashCenter{}
{
...
let range: any;
const elemProps = (await iModel.elements.getProps([elementId])) as GeometricElement3dProps[];
if (elemProps.length !== 0) {
elemProps.forEach((prop: GeometricElement3dProps) => {
const placement = Placement3d.fromJSON(prop.placement);
range = placement.calculateRange();
});
}
...
}
