This is the easiest way to do it.
Roof slope arrow revit.
To create a slope for an odd shaped roof like the one below use slope arrow.
Click again to specify its endpoint head.
Using shape editing tools.
Draw the arrow then click it and change the properties to select the right levels and offsets.
Note that only flat roofs are supported by this tool.
You can use slope arrows to create slopes on a roof.
Then draw the arrow to define the slope direction.
Multiple roof slope arrows can be added to a roof and connected to each other.
For more examples and tips see about slope arrows.
This create an uni directional slope parallel to the arrow.
For instructions see creating a sloped surface using a slope arrow.
The roof by footprint tool can be used to detect a chain of external walls and create a pitched roof based on their boundary.
Roof slope arrow is a tool that allows you to modify slopes on roof elements by defining start elevation and slope or end elevation.
For creating complex roof it might be easier if you create separate roof then use join roof tool to join them later.
You can use height or slope value specify the method and the constraint values from properties palette.
The following example shows a roof that you can create in revit lt using a slope arrow.
This is fine if we know what angle we want the roof slope to be at.
Draw the slope arrow in the drawing area.
But what if we want to create a roof based on absolute heights.
Click once to specify its start point tail.
The tail is the low point and the head is the high point.
Click modify create edit boundary draw tab slope arrow.
Use slope arrows to define slopes on a roof such as a 4 sided gable roof.
The default method of creating a sloped roof within revit architecture is to make one or more of the roof boundary lines slope defining.
