You can create an aligned section view in a drawing through a model, or portion of a model, that is aligned with a selected section line segment. The aligned section view is similar to a Section View, but the section line for an aligned section comprises two or more lines connected at an angle.
You can pre-select sketch entities that belong to the drawing sheet to create aligned section views. The sketch entities do not have to belong to an existing drawing view.
To create an aligned section view:
Click Aligned Section View 
on
the Drawing toolbar, or click Insert, Drawing View,
Aligned Section.
To create an aligned section view with more than two lines,
you must select the sketched lines before clicking Aligned
Section View . The lines must be connected at an
angle and cannot form multiple contours.
Sketch the section line. The section line should consist of two connected lines at an angle to each other.
If you are in a drawing of an assembly, set options in the
Section
View dialog box.
Set options in the Section View PropertyManager.
As you move the pointer, a preview of the view is displayed if you selected Show contents while dragging view.
You can control the alignment of the view. The view is aligned to the sketch segment that was selected when you created the section line; the cut faces from the other segments are projected into the same plane. For information about changing the alignment of views, see Drawing View Alignment and Display.
The orientation of the view flips if you select Flip direction in the PropertyManager.
You cannot change the angle of the line that you selected
to align the view.
Click to place the view.
