Lofting Wires

In this short tutorial, Matas Ubarevičius walks you through the most important aspects of the loft command in Rete editor, which generates free-form surfaces from multiple wires. This powerful algorithm allows you to create smooth, complex geometry quickly.

Matas demonstrates several corner cases to highlight the command’s limitations and various options. You'll work with different cross-section shapes—starting with ellipses and moving on to rounded star shapes. An important requirement is that the wires must contain the same number of edges for the loft to generate a correct and visually appealing result.

Additionally, you'll learn how to convert the lofted surfaces into solid objects. By the end of this tutorial, you'll have a solid understanding of how to use the loft command effectively in your 3D modeling workflow.

Approximate Time Required: 49 minutes

Decompose Solid

Approx. time required: 10 min.

In this tutorial, we’ll take a reverse approach to understanding OCCT (OpenCascade) solid composition by breaking it down into its core components. Sometimes the best way to learn how things are created is by decomposing them into consistent parts.

Wires To Points

Approx. time required: 8 min.

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.

Lofting Wires

Approx. time required: 15 min.

In this short tutorial, Matas Ubarevičius walks you through the most important aspects of the loft command in Rete editor, which generates free-form surfaces from multiple wires. This powerful algorithm allows you to create smooth, complex geometry quickly.

Extrude Shapes

Approx. time required: 8 min.

In this tutorial, you'll learn how to extrude different types of shapes using the OCCT category in the Rete editor on the Bitbybit platform. Matas Ubarevicius will guide you through the key steps for extruding various shapes and explain how different inputs affect the output.

Variable Radius Fillets

Approx. time required: 8 min.

In this short tutorial, you'll learn how to apply variable radius fillets to the edges of an OCCT shape. You'll use JSON editors and other advanced components from our Rete editor to accomplish this.
