IFC is the open, vendor-neutral file format (ISO 16739) that lets different BIM tools share one coordinated model. Here's what IFC and openBIM mean, how they work, and why they protect your project data long-term.
Level of Development (LOD) is a shared language for how detailed and reliable a model element is. Here's LOD 100 to 500 (plus 350) explained simply, and why agreeing it up front saves projects from costly misunderstandings.
4D, 5D, 6D, 7D — the dimensions of BIM are layers of information added to the 3D model, not extra geometric axes. Here's what each one means, plus an honest note on where definitions stop being standardized.
CAD is about drawings; BIM is about information. A clear breakdown of the real differences between BIM and CAD, how their workflows diverge, and when to use each on a construction project.
A plain-English introduction to Building Information Modeling — what BIM actually is, how it differs from CAD, and why it has become the backbone of modern construction projects.
