Changes and improvements of known features

  • The DIALux Start splashscreen has a new layout and shows the progress of loading DIALux


  • Fixed CAD display issues and crashes related to AMD Vega GPUs
  • A change to the energy tool no longer leads to a change in the utilisation profile of the area
  • Isolines can be saved again with a resolution higher than 1lx
  • Crashes during the calculation of some complex projects could be solved
  • Utilisation profiles for indoor and outdoor areas can now only be assigned to the appropriate areas
  • Correction of ULR calculation in road planning

  • Some translation errors have been corrected

DIALux evo 8.1

Version:     |     Released: 2018-11-29

New features

  • Integrated message window with useful hints and information for support in working with evo
  • Two additonal standard objects: hemisphere and cone (truncated cone)
  • Allocation of luminaires that are located in more than one space can be changed to a particular one for documentation purposes
  • Japanese maintenance factor method according JIEG-001
  • Import wizard for DWG/DXF files (similar to image import wizard)

Changes and improvements of existing features

  • Multiselection of single objects with line, field and circle arrangements
  • Image plans that are imported once can be rescaled via import wizard again
  • Change the sorting of road scene results
  • Images can now be deleted in documentation directly
  • Description of objects in project tree is more expressive
  • Speed improvements in working with luminaires and calculation surfaces
  • Speed improvements in loading sophisticated projects
  • Speed improvemtens in exporting DWG files (depends on project size)
  • Speed improvements in rendering documentation
  • Speed improvements in rendering false colours and isolines
  • When creating an object in the scene the allocation (storey, indoor or outdoor) depends no longer on the view that is currently active. The allocation dependends now on object's position itself


      • Documentation of surface results objects is sometimes to small
      • Documentation template "All" is extended by luminaire parts list for exterior area too
      • Issue during visualization of results after combining light scenes
      • Issue during calculation of maintenance factors for luminaires which were not assigned to spaces
      • Issue during loading Evo files greater than 7GB
      • Improved import behaviour for IFC, JPEG and Dialux 4 files
      • Improved import behaviour for SAT models
      • Improved undo behaviour for evo road
      • Issue calculating G* classes in evo road according EN 13201:2015
      • Issue during Drag & Drop of skylights
      • Issue duirng Drag & Drop of luminaires
      • Issue during dimensioning of windows
      • Issue during scaling of ASR calculation surfaces
      • Issue during visualization for element rotation
      • Duplicating a road geometry copies arrangements name too
      • Improved translation

      DIALux evo 8

      Version:     |     Released: 2018-03-15


      • An error has been fixed in the alignment of objects when copying along a line or a curve
      • Typing values in the polygonal line table using »Enter« now works as expected. The focus is now set to the next field
      • An error when moving rotated columns has been fixed
      • An error in scaling of beams has been fixed
      • An error has been fixed for daylight-relevant windows inside of a building
      • The room description is now also included in the outputs of the simple indoor planning

      New functions

          • Using of images as planning basis. Supported are * .jpg, * .bmp and * .png files
          • Support also of several raster graphics as planning basis in one project
          • Import Wizard to specify origin and matching size
          • Import of images via drag & drop
          • Import of images from the Windows clipboard, e.g. via the Windows snipping tool
          • The project start »empty rectangular room« has been replaced by the new function »Room planning«, which allows the creation of any room shape
          • Rooms can now be drawn directly into the CAD. The outer contours are generated automatically
          • When outer contours of different rooms touch, a new outer contour is automatically generated
          • When entering polygonal lines, the lengths of the individual line is now displayed as well as the angle between the lines
          • Lengths and angles of polygonal lines can be entered directly via the TAB-key
          • Entered values are blocked for mouse input, which is indicated by a small lock-symbol
          • When scaling objects the new lengths can be entered directly via the TAB-key
          • All objects can be set to the center of a room or an area via the context menu
          • Each room, floor, building and terrain view has its own coordinate system
          • These coordinate systems can be positioned and oriented by the user
          • All positions and rotations of objects are related to these coordinate systems
          • In the luminaire tool the luminaire efficiency and the luminous efficacy are additionally specified for the lighting data
          • In the luminaire tool a summary of the photometric data is displayed for luminaires with more than one light emitting surface
          • The north orientation is displayed in 3D and 2D with a small preview at the bottom right for each room, floor, building and terrain view
          • The appearance of the north orientation can be shown or hidden in the view options

          Improvements of existing features

              • The standard database was updated to EN 12464-1: 2011 and EN 12464-2: 2014
              • The point grid for calculation areas has been revised.  Each raster  is calculated strictly according to EN 12464-1 and -2
              • The manual is no longer available for DIALux evo. Alternatively there are more up-to-date online resources for this
              • The nodes in the output tree with the room names are sorted alphabetically
              • The drawing of a coordinate system is available on the top of the CAD window
              • The behaviour of polygonal lines and building contours has been revised
              • The behaviour of the table for polygonal lines has been revised
              • The minimum size of calculation areas has been adjusted
              • Measurement files from daylight-guided-light systems (DDLS) can now be send to DIALux evo by drag & drop
              • Luminaires in the road-lighting can now also be deleted via the context menu
              • In the planning results of the road-lighting, in addition to the main arrangement, the secondary arrangements are displayed
