YBC Tube Bending Export — Inventor Tube & Pipe

Export tube bending data from Autodesk Inventor Tube & Pipe assemblies into standard YBC format compatible with CNC tube bending machines. YBC format defines each tube as a sequence of: • Y — Straight length before the bend (mm) • B — Rotation angle between bends (degrees, signed) • C — Bend angle (degrees) This iLogic tool automatically: • Scans your assembly for all tube routes • Extracts 3D sweep path geometry from each tube • Calculates precise YBC values using vector math (cross products, signed rotation angles) • Detects bend radius from tube type designation • Computes developed length for each tube • Exports everything to a clean CSV file on your Desktop Handles multiple tubes across multiple routes in a single run. Includes edge case handling for straight tubes, nearly collinear segments, and complex multi-bend routes. Import the CSV directly into your CNC tube bender software. Eliminates manual measurement and calculation of bend sequences.
