Edificio Geometry EditorEdificio is the VISAC geometry editor. It is designed for use with BRL-CAD models of buildings and facilities. It has several modes for differing tasks, such as editing the geometry or components of buildings or selecting blast points and regions for VISAC incidents.
This page is intended to give just the basics of Edificio for use in running VISAC projects. For a full description of Edificio and its vast editing capabilities, see the VISAC Help page, Edifico Help Table of Contents. The focus here will be Edificio's Cross-Hair mode and Blast Region mode.
The window consists of the viewing canvas, several tools on the left hand side, and several buttons just below the menus. Most of the tools and buttons concern the editing capabilities and will not be discussed here.

In the canvas, the facility is shown from an overhead view. Each building is shown with a different color and all of the walls from each floor are visible. One of the boxes on the left-hand side of the Edificio window is the 'Navigator'. This shows where the current view is in relationship to the full extent of the facility. Users can change which portion of the facility is shown on the canvas by moving the scrollbars of the canvas or by grabbing and moving the black rectangle in the 'Navigator' box. Also on the left-hand side of the window is information listing the groundlevel elevation of the facility. One floor of a particular building can be shown by first selecting the building (by clicking on it) and then adjusting the 'Floor Level' slider bar. Note that the lower portion of the left-hand side of the window now displays some information for the selected building. |

When a floor of building is showing, a new window pops up listing all of the critical components contained on that floor. The two windows work together - selecting a component in one window will highlight the component in the other. This is useful in identifying components. To look at another building, first either set the 'Floor Level' slider of the current building back to floor '0' or close the critical component window. Then select another building by clicking on it. The critical component window also shows a red bar, representing how much vertical space a component takes up relative to the distance between the floor and the ceiling.
Zooming can be done by first clicking on the zoom tool,
. The cursor will change into
a magnifying glass. Place the cursor where you wish to zoom and then click
the left mouse button to zoom in or the right mouse button to zoom out.
When done zooming, reset the cursor to the arrow by clicking on the
arrow tool icon 
.
The walls of each building can be toggled on/off with the tools
and
when no building is selected
or the selected building is at floor 0.
While navigating, the tools
and
can be used to
show the center of the facility and resize the drawing area.
These are useful, for example, if you zoom in too far and get lost.
These features are also available through the options of the 'Edit' menu.
Selecting a Region - Blast Region ModeEdificio can be used to select a circular region of one floor of one building for a VISAC Region Damage incident. First select the building by clicking on it. Next, select the floor using the 'Floor Level' slider.
Now select the 'Set a Blast' icon

Selecting a Blast Point - Cross-Hair Mode
Edificio can be used to pick a blast point for a QuickBlast incident.
A location can be picked
outside of any building or on a floor of a building. For an interior point,
first select the building by clicking on it. Next, select
the floor using the 'Floor Level' slider. For interior or exterior points,
now select the crosshair tool A small dialog box will appear to set the elevation of the blast (feet above sea level). Set the elevation and select 'Commit' to send this point back to QuickBlast or select 'Cancel' to select another blast location. |
