After TRB software realizes 3D view, users can view the 3D shape of the whole floor directly, and show/hide some elements by controlling layers. However, if you want to view some detailed structure and the layout of a room separately or intersecting nodes, etc., you need to use the function Area 3D. This function enables users to view 3D structure of some entities and check the detailed structure of a building.
Area 3D can be used only in the 2D status.
1. Area 3D supports drag-selecting and polyline-selecting, which means that all selected entities will be shown in 3D.
2. Area 3D supports to switch layers with shortcut keys.
3. Area 3D supports to display rebar 3D at the same time.
4. In the area 3D status, if you perform operations such as switching layers, drawing and summary calculation, the software will quit area 3D.
