How 3D Models Transform Construction

3D modelling is essential across films, architecture, interior design, and animation. The fundamental purpose is to accumulate geometry, scene, appearance, and animation data in accessible formats.

Common 3D File Formats

SLDPRT (Solidworks) — Complex CAD designs for engineering and manufacturing.

STEP — Neutral format supporting all 3D modelling software.

F3D (Fusion 360) — Comprises scenes, attributes, and complete 3D model data.

BLEND (Blender) — Stores textures, colours, scenes, and animations.

3DS (3ds Max) — Autodesk’s format for animations and design data.

SKP (SketchUp) — Accessible format ideal for beginners.

IGS — Neutral format compatible across 3D modelling applications.

3DM (Rhino) — Industry standard for parametric surfaces.

IPT (Inventor) — High-quality format compatible with 2D files.

AR and VR Ready Formats

glTF — Adopted by Google for Android AR applications.

USDZ — Created by Pixar; Apple’s standard for iOS VR/AR via Quick Look.

Benefits of Real-Time 3D

See designs before construction, make changes before costly mistakes, optimise utilisation, handle large projects effectively, and create compelling client presentations.

FAQ

Common questions, answered.

What is the difference between STEP and SLDPRT?

SLDPRT is Solidworks' native format for complex CAD designs. STEP is neutral, compatible across multiple software, ideal for manufacturing handoffs.

Which formats are best for AR/VR?

glTF for Google's Android Scene Viewer; USDZ created by Pixar and adopted by Apple for iOS Quick Look.

What are real-time rendering advantages?

Designers catch mistakes during development, visualise designs in detail, and enable faster iteration.
