Frequently asked questions about DIALux
DIALux evo is a 3D CAD application. You basically profit from
powerful CPU and graphics card, and a sufficiently large main memory
(RAM). The main memory should be at least 4 GB. We recommend 8 to 16 GB for
the professional use. A standard multi-core CPU should be available in your
The requirements for the graphics card are mainly a support of OpenGL 3.0.
A large memory is also useful here: at least 1 GB, 2 GB or more is recommended
we to you. Furthermore, your graphics card should have "own memory" and not
have a "shared memory".
Our experience is that there are often problems with (new) drivers of Intel graphics cards so we would recommend a graphics card from Nvdia or AMD. Please hold your drivers as up-to-date as possible.
The following operating systems are supported:
Windows 7 (32/64 Bit) / Windows 8 (32/64 Bit) / Windows 8.1 (32/64 Bit) / Windows 10 (32/64 bit). Please understand that we cannot name a specific computer system.
If there are problems with your graphics card during the installation of DIALux evo we recommend that you first perform a driver update. The installation program for this, loads from the graphics card manufacturer's website.
If you are still experiencing problems after the driver update, please check if more Then one graphic card is installed on your computer system (Optimus System). If this is the case, you have to switch from the graphics card integrated in the CPU to the desired graphics card.
The following links from our DIALux evo forum assist you in doing this:
It is no problem at all to install both of our lighting design products on a computer at the same time. You can in fact even work with both programmes at the same time.
You can import DIALux 4 files into DIALux evo. This works with files that
have been created from version DIALux 22.214.171.124 onwards. But we only import the
Interior planning, this is not possible for exterior planning.
DIALux 4 and also DIALux evo should be installed on your computer. You can use the DIALux 4 file in DIALux evo 32Bit (x86) and import it. Then save the file
and the result as a DIALux evo file. You can also use this file with the 64Bit version from DIALux evo and edit it there.
The answer is yes! DIALux evo is the successor of DIALux 4. The development of
DIALux evo is our daily business. In the version DIALux evo 8.2 all
functions of the predecessor software DIALux 126.96.36.199 are implemented, with the exception emergency lighting, lighting of sports complexes and the creation of videos. We will add the missing functions for you in DIALux evo .
You can choose between "Standard" and "Fast" in the calculation settings. With Standard the whole project with all its light scenes is calculated.
After switching to "Fast" DIALux evo always calculates only your selected
Light scene. In addition, the calculation is limited to the view that you can see in the navigation selected. If you see a room, only this room will be calculated.
If you are currently in a floor view, this floor will be calculated. Have you selected the exterior space in CAD, DIALux evo only calculates the lighting outside and ignores all the interior space.
We recommend you to use these settings to save time for larger projects.
DIALux evo is developed for Windows.
We know from some Mac users that it is possible to run DIALux evo on a Mac to
install and use. These users use virtualization software such as
Parallels or Fusion to set up a Windows guest system. A search engine can help you for more information.
Please understand that we do not provide support for problems on Mac systems.
To log in to DIALux Mobile for the first time, it is necessary that you confirm your e-mail address. After you have completed the registration you will receive a confirmation link by e-mail, which you have to click once. Without this confirmation you will receive the error message "Invalid Login" when logging in.
Please note: Depending on the region, it may take a few minutes or longer before the e-mail with the confirmation link can be delivered. Please also check your spam folder.
The current version of DIALux Mobile is free of charge for users and is funded by advertising and license fees from manufacturers who make their products available for planning.
DIALux Mobile is available for iOS and Android and can be installed on both smartphones and tablets.
As with DIALux evo, you plan with real products from leading manufacturers in DIALux Mobile. An online database with a convenient search function and over 250,000 products is available for product selection. Import of local photometry files (ULD, LDT, IES) is not possible.
In certain cases, manufacturers or products may be available for planning in DIALux evo, but may not be available in DIALux Mobile. This is a decision of the manufacturer. In this case, please contact the manufacturer directly.
An internet connection is required to perform a product search. The calculation and the generation of result graphics also take place on our server. This preserves the battery life of your device. As long as you are offline you can only open existing projects.
You can access your projects on another device if you sign in there with the same username and password.
It is not yet possible to hand over projects to DIALux evo, but this is one of the features we want to offer in one of the upcoming versions.
DIALux Mobile uses the zonal cavity method as its calculation method. This method is suitable for an approximate calculation and the determination of the required number of luminaires for an average illuminance. DIALux evo delivers a much more precise result because it uses a point-to-point calculation method.
We still have many ideas for DIALux Mobile, e.g. we are planning professional functions such as a point-to-point calculation that enables more precise results, a statement on the uniformity of illuminance or a visualisation of isolines. We would also like to make it possible to output the results as a PDF or to hand them over to DIALux evo. However, there is no timetable for these features yet.
