You can cut through any portion of your model to create a section view. Section views are a great way to see the interior features of your model that you are not able to see from the outside.
To create a section view, you draw a section line through your model in 2D plan view, then click to define the view direction and depth.
To create a section view:
Make sure you are in 2D plan view.
Select View
> Section Views > Create New Section, or click the Section
Views button on the Advanced View Control toolbar and select Create
New Section.
Select two points to draw a line that cuts through your model. This is the line you will be viewing from.
Move your cursor in the direction you want to
view. The more you move away from the section line, the deeper your view
becomes. Once the bounding box is the desired distance and direction from
the section line, click to finish.
Once you’ve defined the section mark, the resulting section view is instantly displayed. It is also added to the Section Views menu and toolbar flyouts for easy access. (By default, the first view you create is called Section1.)
