How to Create a Living Room using Basic Shapes in 3D CAD Software (Part 1)
3D modeling is not only about creating highly detailed and complex objects; sometimes the most effective designs begin with the simplest building blocks. By learning how to combine basic shapes such as cubes, cylinders, and spheres, designers can construct realistic scenes that capture both function and style. SelfCAD, a user-friendly online CAD program, is especially well-suited for this purpose, offering accessible tools that allow beginners and experienced users alike to experiment with digital design.
In this article, we will explore how to create a living room scene in SelfCAD using only basic shapes. This project demonstrates how everyday furniture and interior elements, such as sofas, tables and shelves, can be modeled from simple geometric forms. Through step-by-step instructions, you will discover how scaling, aligning, and grouping shapes can transform simple objects into a cohesive and realistic room layout. The goal is not only to practice fundamental modeling techniques but also to show how imagination and creativity can turn basic geometry into a complete and visually appealing environment.
