✅ Drag, push, pull → Create 3D objects in seconds.
✅ Pre-built models → Download sofas, lamps, cars, plants directly from the 3D Warehouse.
✅ Cross-industry use → Architecture, interior design, furniture design, urban planning, landscaping, even gaming.

💡 In simple words: SketchUp turns your imagination into 3D reality.

• For DIY/Homeowners → Plan your dream kitchen, balcony, or bedroom before spending money.

• For Students → Easy to learn for school/college projects, portfolio-ready.
