Prepare the pipe ends
Position pipe cylinders so their relevant ends are near the fitting location. Check axes, diameters and orientation before creating additional solids.
Create a reducer
- Run
3DPreducer. - Select the two pipes of different diameters in either order.
- The nearest end of each cylinder is identified automatically.
- Circular profiles are created perpendicular to each axis and lofted into the reducer.
- The source pipes remain in the drawing.
Collinear axes produce a concentric reducer. Offset axes produce an eccentric loft, so confirm that the model arrangement matches the intended fitting.
Video placeholderCreate concentric and eccentric reducersUse the same pair of diameters and clearly show the axis difference.
Add a flange
Run 3DPFlange and select a pipe cylinder. The flange is created as a disc perpendicular to the pipe axis at the cylinder base. The current command derives its size from the selected pipe radius.

Model checks
- Confirm the selected end is the intended fitting location.
- Check reducer axes and transitions in more than one view.
- Verify flange dimensions against the project standard before fabrication use.
- Keep fittings as separate solids when later editing or scheduling is expected.
