Rotating a Section Annotation


Snaps are great in Revit and assist us with aligning many objects, but sometimes get in the way or inadvertently cause us to make an error.  Let’s say for this example we have placed a Section Annotation (Building or Wall) and didn’t quite make it perpendicular to the wall we want to section.  If the view created is not normal to the object being cut, we cannot utilize our tools, such as dimensions, with it.

Non-aligned Section Annotation

One Works, One Doesn't

What do we usually do?  Delete and redraw.  Nothing wrong with that, but it is possible to rotate these objects and “align” them properly when the case calls for it.

Annotation End Points

Annotation End Points

The Section Annotation actually has a couple end points we can utilize, and it is good to note that the annotation can snap to Reference Planes and Structural Grids when first creating them.  I’ll describe the use of a reference plane and those end points to make the rotation dependable.

I use a reference plane because I can specify a snap override to make it perpendicular to a wall (SP shortcut).  I then can “trace” another reference plane over the section annotation by snapping to each of the endpoints found at the tail and head of the section.

Draw Ref Plane Over Annotation

I then move the section and ref plane together snapping nearest to the already created ref plane.

Move To Good Ref Plane

Once there and the two objects selected I can use the Rotate tool and definitely snap the rotation to the “good” ref plane, ensuring its alignment.

Rotate Annotation

It is possible to just use the Rotate tool on the Section Annotation itself and snap to one of the endpoints on the annotation.  You don’t really get a snap alignment with the annotation, but if you pick an arbitrary position near the annotation, you can perceive the automatic snapping perpendicular to the wall as you rotate.  I find that this doesn’t always happen though, based on what, I’m not exactly sure.  So, if I need to do this I prefer the ref planes method.  But at times in Revit, we just need to draw a line, or in this case maybe just delete and redraw the section.
