Offset bending

From input to answer.

Open All Tools → Bending. Choose Offset.
Select conduit material and size, then a matching bender setup. Confirm its centreline radius and any tool-specific reference values.
Enter centreline rise, bend angle and your end/finished-length arrangement. Read the layout and any warnings.
Switch between 2D layout and 3D explore to inspect the run. Use Guide me through this offset, review the checks and advance through the steps.

WORKED EXAMPLE

A 6-inch offset at 30°

Enter

For a geometry check, use 6 in centreline rise, 30° bends and a 4.625 in centreline radius. Conduit outside diameter is 0.706 in.

Read the result

The curved bends leave about 9.52 in of straight between their tangencies. Bend-centre spacing is about 11.94 in, with about 1.49 in geometric shrink across the offset. These are geometry values, not universal shoe-arrow marks.

Get more from it.

Measure rise between conduit centre lines. Obstruction height alone may omit required clearance.
Use the bender and conduit combination you actually have. A trade size is not the outside diameter.
In 3D, inspect direction and orientation before bending. The guide’s reference labels matter as much as the numbers.

Know the limits.

Finite-radius geometry can differ from a simple rise × multiplier table. Very small rises may not fit the chosen radius and angle.
Tool calibration, grip, springback, floor position and real obstruction clearance still need independent checks. A rendered shape does not prove it can be bent on your equipment.

Common questions.

Is the basic offset included in the free app?

Yes, including its 2D/3D views and build guide. Other bend types require Premium.

Can I try the calculation online?

Yes. The online offset calculator covers the core geometry; the app adds the equipment workflow and build guide.
