About Creating a 2D or 3D Section or a Live Section View Workflow

Task Comment
Draw a section line The section line defines the extents of the section (its depth height, and length) to extract from the building model for 2D, 3D, and live section views.
Create a 2D or 3D section or a live section view Create a 2D or 3D section by placing the generated section. All objects within the section volume are automatically selected to display in the section result, except for objects that are hidden or are on layers which are frozen or turned off.

Live section views are created from the section line. All objects in the drawing are automatically included.

Make changes to the section line or the building model You can edit the section line and the section object to refine the appearance of the objects.
Update the section Update sections to apply changes you made to the section line, the section object, and the building model. You can also globally update all sections within a project or a specified folder all at once.
