Polypipe Terrain Fuze HDPE

This free collection of Revit content is perfect for modeling drainage systems for waste and sewage, chemicals, hazardous waste and more.

Following up on last week's collection of cast iron no-hub pipe from Charlotte Pipe, this week's collection of free Revit content focuses on another set of drainage piping – Polypipe's Terrain Fuze HDPE pipe.

These Revit families are the byproduct of previous consulting work for Mecserve. They were created in order to address some issues with drainage coordination and proved a very valuable tool. Our Terrain Fuze HDPE collection has all of the fittings required to configure the pipe type's routing preferences in Revit.

While both this collection and the previous Charlotte Pipe collection feature piping content for drainage systems, there are some key differences between the Charlotte no-hub pipe and the Polypipe Terrain Fuze:

CouplingSteel Mechanical JointHDPE Coupling (electrofusion welded)
Drainage UsesBasic waste and sewage Waste and sewage, chemicals, hazardous waste, compressed gases

Nested Couplings

We are in the process of updating all our pipe fittings and pipe types that have any couplings set as flanges. We do this to avoid a problem in Revit where moving the 45 deg horizontal pipe would also move the stack locations. The solution involves having nested couplings in the pipe fittings.

The couplings can be turned off manually to allow coordination of fitting to fitting with a shared coupling.

IsCustom Option

The Terrain Fuze HDPE fittings include the IsCustom option. The IsCustom option allows the Revit user to create piping systems with a more fluid workflow. Whenever there is an incorrect value for angle or nominal diameter (depending on the fitting), Revit will allow the pipe to be drawn but will flag that this is a custom fitting and will color it red.

This pipe range has been given a 2 degree tolerance. For example, the 88 deg bend can produce an 86 - 90 degree bend and still return the correct Polypipe product code.


The reducer fitting is a true Revit reducer, unlike some of the reducers you may find nowadays from the Revit OOTB library. This reducer will work with both JUSTIFY and SLOPE tool in Revit, switching seamlessly between the two.
