The following types of views are available in ETABS.
Three-dimensional (3-d), with button
Plan, with button
Elevation, with button
Perspective Toggle, with button
in a Plan View. When this button is clicked in a plan view, the view switches to a 3D perspective view.
If the plan view is of a story level, the 3D perspective view shows only the objects that are associated with that story level. Objects associated with other story levels are not shown.
If the plan view is of a reference plane, the perspective view shows only the objects associated with the story level with which the reference plane is associated.
in an Elevation View. When this button is clicked in an elevation view, the view switches to a 3D perspective view of the entire structure. The initial direction of the 3D perspective view is looking directly at the elevation that was displayed, with the elevation angle set to 0 degrees and the aperture angle set to 60 degrees. If the elevation displayed is a developed elevation, the initial direction of the 3D perspective view is looking directly at the first segment of the developed elevation.
in a Three-Dimensional View. When this button is clicked in a three dimensional window, the view switches from a perspective view to an isometric view. In other words, the aperture angle is toggled to 0 degrees.
Note: As the name indicates, the Perspective Toggle button is a toggle switch. Thus, it can be used once in a plan view or elevation view to switch to a perspective view of a story level, or in a 3D view to switch to an isometric view of structure. If the Perspective Toggle button is clicked again in this same view, ETABS will switch back to the original plan, elevation, or 3D view. While in the perspective view (plan, elevation), the Rotate 3D View button, , is active and can be used to adjust the view direction.
