Learn How to Extract Points from Wires in OpenCascade OCCT Components Using Rete Visual Programming

This tutorial is part of the OCCT IN RETE series

In this short beginner-friendly tutorial, you will learn how to divide wires into multiple points using the powerful OCCT (OpenCascade) components available in the Rete visual programming editor on the Bit by bit developers 3D platform (bitbybit.dev). Guided by Matas Ubarevicius, this tutorial offers a step-by-step approach to working with wires, making it ideal for those new to visual programming or looking to enhance their 3D modeling skills.

We’ll begin by introducing some of the most useful OCCT components that allow you to divide a wire based on parameters. You’ll learn how to divide a wire by equal distances or place points along it based on specific lengths. This tutorial will also cover more advanced methods, including using length patterns for point extraction, which gives you greater control and precision in your designs.

Throughout the tutorial, we’ll explore key techniques such as how to extract points at given lengths along a wire and how to make use of various wire division strategies to customize your workflow. Whether you’re working on 3D models for engineering, design, or architecture, these tools will be invaluable.

By the end of the video, you’ll have a strong understanding of wired point extraction within the Rete editor. You’ll also gain access to example scripts that you can find in the public projects section of the platform, enabling you to experiment and build upon what you’ve learned. This tutorial is perfect for both beginners and more experienced users looking to deepen their knowledge of OpenCascade in visual programming.

Be sure to watch through to the end to fully master these techniques and bring your wire-based 3D projects to life!
