If you want the range, use readGltf instead.

RenderGraphic is an intentionally opaque type and it may or may not have any number of branches, etc. Please explain what you are trying to accomplish that leads you to want access to its internal structure. Note, readGltf and readGltfGraphics are designed to produce graphics; they are not intended to parse and return a glTF document. Plenty of libraries for that already exist.

const branch = new GraphicBranch(); branch.add(graphic); graphic = IModelApp.renderSystem.createGraphicBranch(branch, transform) const rangeBox: Range3d = graphic?.branch?.entries[0]?.branch?.entries[0]?.range;

i am trying to access range which is needed to create bounding box
