Section

Sectioning lets you cull the model to focus on a certain spatial area. This is different than hiding an individual item in the view or turning off the display of a category because only part of the item displays if it falls on the cutting plane. This allows you to see inside of a building without having to manage large lists of hidden items.  You can navigate, turn off individual items or categories as well as use Data Visualizations while a section is enabled. 

Sectioning Tools

There are 4 different sectioning tools that are available:

	Section By Plane	Slices the Model with a 2D Plane. The orientation is determined by the selected surface. The plane can be moved after it is created.
	Section By Element	Slices the Model as a box around the selected element.
	Section By Range	Slices the Model as a box using the selected points as opposing corners of the box.
	Section By Shape	Slices the Model as a box that is manually drawn by the user.
