Process Overview: Creating a Live Section View
Creating a live section view of a building model entails the following:
Step 1: Draw a section line.
For more information, see “ Drawing a Section Line and Marks ” on page 1772.
Step 2: Switch into a 3D model view.
Step 3: Enable the live section view.
Drawing and Editing Section Lines
The first step in creating a section is to draw a section line through the building model. The section line defines the
extents of the section to extract from the building model.
NOTE You can create vertical sections and horizontal sections.
Creating a Section Object from a Section Line
When you generate a section from a section line, you specify the type of section object that is created.
The result is… When you create…
an orthographic projection from the building model. a 2D section object
the area of the building model defined in the section line. a 3D section object or a live section
Creating a Live Section View from a Section Line
When you create a live section view from a section line, you do not create a new section object but instead switch to
a special view of the 3D building model. You do not select objects to include in the section; the live section view
includes all objects in the drawing. The section line controls how objects are displayed in a live section view. Objects
or parts of objects that are within the bounding box of the section line retain their original display properties. Objects
or parts of objects that are outside of the section line are either not displayed at all or are displayed with a special display
component for the sectioned body.
Viewing the Section Line
In plan view, the section line is displayed as you would expect on a construction document. The section marks point
in the direction that the section is cut.
Viewing the section line and mark in plan view
In an isometric view, the same section line is displayed with a boundary that defines the extents of the section.
