Saving a DWG file is done in DIALux evo 5 in five steps.

  • Change to the export mode and open the DWG export
  • Selection of light scene and matching 2D or 3D view
  • Configuration of the DWG layers, layer colors, etc.
  • Selection of the calculation areas for isolines and value graphics.
  • Saving DWG file

Step 1:

Change to the export mode and open the DWG export:

To export a DWG file you have to select the export mode and activate the third tool (see image Export_Overview(1)).
From here you can start configuring the DWG.


Step 2:

Selection of light scene and matching 2D or 3D view:

Basically, evo 5 gives the option to save results in addition to the geometry in the form of value graphics and isolines as own layers.
But as results depend on a light scene, evo delivers such results always for the currently selected ligt scene (see image Export_Overview(2), circled in red ).
If you want to export the results of multiple lighting scenes, so you have to switch to the desired light scene and save another DWG file.
So evo supports one DWG file per light scene.


Evo operates on the principle: What you see will also be exported.
In the example below (see image Export_SetScope3D) the storey "Ground floor" is selected for the 3D view.
The DWG export will save a DWG file for the floor as a 3D DWG in this case. For example, select the view of a room, so a DWG file is saved only for this room.

If you want to save the lighting design for an entire building to a DWG file, evo will approach level by level when exporting.
This means you get every floor exported in its own layer.


But, if you select a 2D view, for example, the plan view will be saved as a 2D DWG file (see image Export_setScope2D).

Step 3:

Configuration of DWG layer, layer colors, etc.


After chosing a light scene and a view, you can configurate the DWG on the left side (see image Export_Configuration(1))

Export_Configuration (1)

On the left you can see the contents which can be saved for the selected view later in the DWG file.
Through the ticks you have the option to select and deselect content and therefor DWG layer.
You can see directly that the objects are shown or hidden in the CAD view.
Further you have the option to select a color for the DWG layer over the color selction dialog (see image Export_Configuration(2)).

Export_Configuration (2)

In the example shown above, the isolines and their layer would all be red.
In the table below you can see a list of all possible DWG layer.
Especially for the lights, the isolines and the graphic values you can make a finer adjustment using the sub-sections.


  • All luminaires of the view are stored in a single DWG layer (Default)
  • For each type of luminaire (product) a DWG layer is crated and the same types of luminaire can be found on a layer.
  • For each luminaire arrangement, you have created during your lighting design, a layer is created on which only the luminaire of this arrangement can be found.


  • There is one layer created per photometric unit and the isolines created on this.
Evo determines here initially how many different lighting units are available in the visible CAD calculation surfaces (Default).

In one view, there are three calculation surfaces which provide two horizontal illuminance and one hemispherical illuminance as a result.
Evo will create two layer. One for the results of the horizontal illuminance and another for the results of the hemispherical illuminance.
Then the isoline graphics for each calculation surface are created on the appropriate layers.

For every result of a photometric quantity an own layer is produced, in which only one isoline graphic for one result is shown.

A word of advice:

The isoline and values graphics need some time to generate. If you select the tick for isolines and value graphics, 

you will notice no change in the CAD view. These are created later when saving the DWG file.

Value graphics:

The settings are similar to those of the isolines, only with the difference that values graphics and isoline graphics
should always be disconnected and can not be exported on a layer together.

Step 4:

Selection of calculation areas for isolines and values graphics

The DWG export will basically save all visible calculation surfaces in the DWG file.
There is the option to exclude individual surfaces from the export on the results overview. Hereby you have the option to choose exactly for which areas results will be exported. To do this first open the result overview (see image 

Export_Configuration (3))

Export_Configuration (3)

Via the eye icon you can individual show or hide calculation surfaces. 

Showing and hiding the calculation areas also appears directly in the CAD.
For surfaces that are visible, results, isolines and values graphics are generated.
For areas that are not visible, no results are saved in the DWG file (see image Exort_Configuration(4)).


Step 5:

Saving DWG file

After configuring the DWG contents you can save the file by calling the action "Export to new file",
assign a file name and then press the "save" button (see image Export_Final).
Depending on the complexity of the project, it may take a little time now.
The status bar shows a progress bar and a message appears when the DWG file was saved.

Description of the DWG layer shortcuts 

The DWG layers exported by DIALux all begin with the shortcut DLX_.
DIALux evo automatically numbers the layer for buildings BLD0_ ....BLD3_ and floors FL0_...FL2_ if it is more than one building, more than one floor per building designed.
