# How to Design Brainvita Using 3D CAD Software **How to Design Brainvita Using 3D CAD Software** Brainvita, also known as Peg Solitaire, is a popular single-player board game that challenges logical thinking and problem-solving skills. Designing a 3D model of Brainvita requires precision in creating the board and the pegs while maintaining an optimized structure for digital or physical use. SelfCAD, a user-friendly [3D modeling software](https://www.selfcad.com/), provides an efficient platform to design such models with ease. In this article, we will explore the step-by-step process of designing Brainvita using SelfCAD. From creating the circular board to placing the pegs accurately, this guide will cover essential tools and techniques to achieve a well-structured low poly model. Whether you're a beginner or an experienced designer, mastering these skills in SelfCAD can enhance your ability to create functional and visually appealing 3D models.
