Import a gbXML file as a scene

Kurt Bieri

The Green Building XML format (gbXML) has been designed as an open data format. 

GbXML allows you to easily transfer building data (building hierarchy, geometry, daylight openings, doors, etc.) 

from Building Information Models (BIM) to engineering or analysis software.

Currently, GbXML is being integrated into a variety of CAD programs and Engineering Tools and supported by leading 3D BIM vendors.

The new ReluxDesktop 2017 - provides, like the CAD Import - two different possibilities of importing gbXML files. 

The first option involves selecting the option “Project Import” in the Start menu of ReluxDesktop and creating several new scenes using an imported gbXML file. 

In this, any existing doors or windows are placed at the same time. 

The second option is to import more gbXML data into an existing project. 

Follow the “New project -> Interior with 3D information”.

Clicking on the option “Interior with 3D information” opens up as usual the input window for the project data.

Dialog window “Enter Project data”

As early as the next step, a gbXML file can be imported in the menu “Import Room”.

Other preparations or creating the building hierarchy (Building -> Floor -> Scene) is not necessary 

because all scenes are already assigned logically to their floors when importing.

Furthermore, in the plan view all the scenes are placed in their correct positions, allowing the user a rapid overview of all floors along with the scenes. 

In this regard, the current version of ReluxDesktop differs considerably from previous versions.

So as to start planning lights and lighting systems for individual scenes, it is necessary to move from the floor overview into a single scene. 

By double-clicking a room enclosing wall switch into the desired scene and enable the editing mode. 

As usual, working with ReluxDesktop is convenient despite a possibly large number of scenes. 

The newly-named menu group “Project” (see Figure below) allows you to switch back into the floor overview if necessary.

Menu group “Project”

In the menu group “Project”, as usual, a so-called combo is located in the middle. 

On clicking, the list of all available levels is displayed and, slightly indented, also the list of all available scenes. 

Here, you can select individual rooms, or switch between the floors of a building.

The following two figures show the view of a ground plan in the floor overview, and then in the editing mode of a scene.

A double-click on the room enclosing wall a currently active scene (editing mode) opens up as usual the dialog “Properties”

In the four different tabs, various parameters such as name, location, and northern angle, target values, measuring surfaces, structure and reflectance 

can be viewed and changed if necessary (see following five figures).
