Every new interior design student asks some version of the same question in their first week: "Which software should I actually learn first?" The honest answer is that it depends on what stage of a project you're solving for — drafting, modelling, or visualisation are three different jobs, and AutoCAD, SketchUp and 3ds Max are each built for one of them.

AutoCAD — for precision and working drawings

AutoCAD is where a design becomes buildable. It's the industry standard for 2D floor plans, elevations, sections and the detailed working drawings a contractor will actually construct from. If you're just starting out, this is almost always the right first tool — it teaches you to think in exact measurements, layers and construction logic, which every other tool assumes you already understand.

SketchUp — for fast 3D thinking

Once a 2D plan exists, SketchUp is where you test whether the idea actually works in three dimensions. It's intentionally simple to learn, which makes it the fastest way to turn a flat plan into a massing model you can walk through, share with a client, or use to catch spatial problems before they become expensive ones.

"AutoCAD tells you if the design is correct. SketchUp tells you if it actually feels right."

3ds Max, V-Ray, Lumion & Enscape — for the final presentation

These are visualisation tools, not design tools — they come after the design decisions are already made. 3ds Max with V-Ray gives you the highest control over photorealistic renders, while Lumion and Enscape are built for speed, producing walkthroughs and real-time views that are ideal for client presentations under tight deadlines.

A simple learning order

Trying to learn all four at once usually backfires — students end up with shallow knowledge of everything instead of real command over one tool at a time. Sequence matters more than speed here.
