Patch 2
Version: 5.12.0.5620 | Released: 23/11/2023
Fixed were among others:
- RUG calculation
- Problems in the documentation
- Number of grid points in the street could not be changed
- Security updates (Chromium and .NET)
- SilentSetup did not work if .NET 6 was not already installed
Patch 1
Version: 5.12.0.5586 | Released: 26/10/2023
- Even if the luminaire catalogues are open in the background, projects can be saved again.
- If Thai is set as the language, older projects can be loaded again.
- For our test infrastructure, we implemented something in the luminaire list that made it extremely slow to open. The luminaire list should open quickly again.
- We have solved connection problems from DIALux to our online services. This affected users who had configured a proxy server.
- We use software libraries from other suppliers for DIALux. Due to an update of such a library, luminaires were incorrectly oriented during the DWG export. This should be fixed with this patch.
- We have fixed issues when combining objects.
- The numbering of the luminaires in the luminaire layout plan are now sorted in ascending order per arrangement.
- Various translation corrections.
DIALux evo 12
Version: 5.12.0.5527 | Released: 20/09/2023
IFC Import
DIALux now supports the complete IFC structure in the form of a tree diagram. You can now decide which IFC objects to import into DIALux. This version supports the formats IFC 4.0 and IFC 4.1, including the geometry descriptions of version 2x3. In the future we also plan to support newer IFC geometry formats.
We have introduced a new tool called "IFC Model" under the "Construction" menu to work with the new IFC objects. When you select them, you get detailed information including global ID, IFC type, name and description. These IFC objects can be removed from the scene using the tool.
For example, to save calculation time, you can decide to exclude the new IFC objects from the calculation or to simply illuminate them. DIALux treats the new IFC objects similarly to furniture, especially if no furniture and no IFC objects are present.
The new IFC objects are also the content of plans in the documentation. The objects can be selected and deselected from the page settings.
At the end of the design, you can export the lighting model as a separate IFC file. In this release we limit the file format to IFC 2x3 and you can specify whether the IFC file should be compressed at the same time or saved as IFC XML for web applications. Such a partial model can be returned to the BIM process to extend a common building model. The alternative: The partial model can be used as input for other Open BIM-enabled CAD programs.
Scope of the IFC export
DIALux takes the building structure such as terrain, buildings and floors from the IFC building model. All luminaires are drawn into this building structure with their correct 3D geometry and coordinates (WYSIWYG). The export takes the length unit from the building model. Articulated luminaires are exported as a fixed model in their fully aligned state.
In addition, each drawn IFC luminaire has the following properties:
- Item name
- Item number
- Item description
- Manufacturer
- Mounting type
- Reference surface (floor, wall, ceiling)
- Emergency lighting operation possible (yes/no) Product feature
- Total system connected load (sum of all Leos)
GLDF
With DIALux evo 12.0 you can import luminaire data in GLDF format. GLDF (Global Lighting Data Format) is a new, modular lighting data format with a clear XML structure that describes simple to complex luminaires and sensors. It is an open and freely available data format. More information is available at gldf.io.
Luminaires from DIALux members can be imported in the usual way using drag and drop or the import function. In addition, GLDF data can contain different product variants that differ in terms of electrical, photometric or appearance. The variant is selected during import. GLDF data from non-members can also be imported, but will be subject to the previous restrictions.
GLDF also supports the new L3D geometry model. The new L3D editor makes it easy to create luminaire models from OBJ data.
Changes to familiar functions
- As part of the Open BIM development, the contour recognition of rooms from IFC building models has been improved. This allows DIALux to now process IFC models that were previously unable to be loaded
- The Solid Modeler Library (SMLib) has been updated, various errors have been fixed, and improvements have been made to the Solid Modeler
- The IFC import feature has become more tolerant. If IFC objects cannot be loaded, DIALux will attempt to skip them instead of aborting the import process
- The processing of standard daylight control systems has been slightly accelerated, as well as the calculation of potential energy assessments
Bugfixes
- Issues with loading projects
- Errors when generating outputs and when creating calculation surfaces
- Errors in charting on the calculated road
- Adjustments to tooltips for forward/backward navigation
- Correction of translation errors
- Error in the number of placed windows
- Performance improvement when loading daylight systems
- Resolution of an issue where deleting the last luminaire group also deleted the lighting scene
- Renaming option for the emergency lighting scene and improvement in documentation presentation to display location information above the heading on image pages as well
