To export part of a 3D view, use a section box to define the part of the 3D view to export. By applying a section box, you are limiting the amount of the model that is exported. Elements that are completely outside the section box are not included in the export file.
The section box is particularly useful for large models. For example, for an interior rendering of a conference room in an office building, use a section box to export the conference room and omit the rest of the building.
To create a duplicate view
Add a section box
Export the 3D view defined by the section box
The duplicate view displays in the drawing area. In the Project Browser, the duplicate view is named Copy of <View Name>.
This is the 3D view that you will export. Saving the view allows you to easily export it again later if you make revisions to the model.
The section box displays in the drawing area.
It may be easier to control the size, shape, and position of the section box from another view (such as a floor plan), as follows:
