How to model a gutter on a sloping roof edge – Revit

Last updated July 29, 2026

Problem: Revit ‘Roof: Gutter’ tool only works on horizontal edges. How do I model a gutter on a sloping roof edge? For example a skillion roof with a 45 degree edge.
Applies to: Revit 2014. but probably applies to all previous versions too.
Solution: Use ‘Model In-Place’ with a sweep and use “Pick 3D Edges”.
Step-by-step guide:

 

Revit 3D view of a skillion roof, shown in blue, sloping over brown walls with a 45 degree edge - the roof this gutter will be added to
Step 1: Model your roof, in this example a skillion roof with 45 degree edge

 

Revit Architecture ribbon with the Component drop-down open, showing Place a Component and Model In-Place, and the Model In-Place tooltip explaining it creates a component unique to the project
Step 2: Architecture Ribbon > Component > Model In-Place

 

Revit Family Category and Parameters dialog with Roofs selected in the category list
Step 3: Select ‘Roofs’ category

 

Revit Name dialog with Gutter typed into the name field
Step 4: Type ‘Gutter’

 

Revit in-place editor Create ribbon with the Sweep tool hovered, tooltip reading Solid Sweep - creates a 3D shape by sweeping a 2D profile along a path
Step 5: Create Ribbon > Sweep

 

Revit Modify Sweep ribbon with Pick Path hovered, tooltip explaining you can select edges of 3D geometry in multiple work planes to define the sweep path
Step 6: Modify Sweep Ribbon > Pick Path

 

Revit Modify Sweep, Pick Path ribbon with Pick 3D Edges hovered, tooltip explaining it locks sketch lines to the selected geometry so a 3D path can be sketched
Step 7: Modify Sweep Ribbon > Pick Path > Pick 3D Edges

 

The sloping roof edge highlighted in Revit with the status tip reading Roofs: Basic Roof: ROOF SHEETING: Edge, showing the edge being picked for the gutter path
Step 8: Pick the edge of your roof where gutter to be located
Revit Modify Sweep, Pick Path ribbon with the green tick hovered, tooltip reading Finish Edit Mode, and the picked roof edge highlighted along the eave
Step 9: Click green tick

Step 13: Click green tick
