What a header parse can tell us before the full file parse (issue #301).

interface ModelInfo {
    byteLength?: number;
    fileName?: string;
    originatingSystem?: string;
    preprocessorVersion?: string;
    schema?: string;
}

Properties

byteLength?: number
fileName?: string
originatingSystem?: string
preprocessorVersion?: string
schema?: string

e.g. 'IFC4', 'AP214', or a non-STEP format tag like 'GLB' / 'FBX'.
