Trim levels tool works similarly to trim and extend tool of revit.
Revit 2018 trim roof with plane.
Trim extend level 3d.
Split face divides the face of an element into regions for application of different materials.
For example use cut geometry to cut a column to a certain height or to stop a beam at a wall.
I have actually selected the left hand reference plane you can see that i have also named it roof start.
Revit places a reference plane at the specified offset.
Trim extend to corner trims or extend one or more elements to form a corner.
To raise or lower the roof from the reference level specify a value for offset.
Trim or extend level 3d extents to the reference grid reference plane or detail line as a boundary.

Naming reference planes makes it easier to track their.
Sketch the profile of the roof as an open loop.
Levels 2d extent will switch to.
1 create another named ref plane in plan view so as to draw the roof profile roughly at end of roof image 1 2.
Go to end view of roof elevation face on to new named ref plane select roof by extrusion the select new named ref plane from drop box.
Use the cut geometry tool to cut a structural member with a plane.
Click modify tabgeometry panelcut drop down cut geometry.

Reference plane creates a reference plane using drawing tools.
With it you can easily trim or extend one or more levels to a boundary defined by grid reference plane or detail line.
This method is worth learning so when plane moves everything goes with it.
