OCCT Operations

The OCCT operations that turn flat profiles into three-dimensional solids in Bitbybit - extruding, lofting, offsetting and thickening. This is where a sketch becomes a shape: extrude a wire along a direction, loft through a series of profiles to get a smoothly changing form, revolve a profile around an axis, or offset a face outward to give it wall thickness. These pages cover each operation and its inputs, simple and advanced lofting, rotated extrusions, offsetting single and multiple wires, and building thick solids from complex faces.

📄️Simple Loft Tutorial

Learn how to create a surface by lofting between several wire shapes.

📄️Advanced Loft Tutorial

Learn how to create a surface by lofting between several wire shapes and use various advanced options that help you make more intricate shapes.

📄️Offset Operations

Learn how to create offset shapes using various offset operations in OCCT - from simple wire and face offsets to advanced thick solids.

📄️Extrude Wire And Face

Learn how to create a 3D shape by extruding a 2D wire profile or face.

📄️Thick Solids

Learn how to create thick solids from complex lofted surfaces using OCCT operations - from curved wire interpolation to volumetric solid creation.

📄️Rotated Extrusion

Learn how to create 3D spiral or helical shapes by extruding a 2D wire profile along an axis while rotating it.

📄️Wire Offset Multiple

Learn how to create multiple parallel offsets from a single open wire using OCCT operations for various design and manufacturing applications.

📄️Sections and Slices

Cutting OCCT shapes for drawings and fabrication - slicing a solid into layers, cutting it with planes or frames, splitting it with other shapes, the outline where two shapes meet, and hidden-line views for technical drawings - with an example in Rete, Blockly and TypeScript.

📄️Pipes and Sweeps

Sweeping a profile along a path with OCCT - round tubes and polygon bars along any wire, your own profiles with pipe, profiles that grow or shrink on the way, and mouldings that follow a flat outline - with an example in Rete, Blockly and TypeScript.
