00_Curved walls and ceiling in DIALux evo_irregular shape for walls

Making Curved walls
The fist step is to define the maximum depth or wall thickness  01_Curved walls and ceiling in DIALux evo_irregular shape for walls
You can put the thickness in the wall thickness.

alternately you can modify the wall thickness after creating a room by the following steps

 02_Curved walls and ceiling in DIALux evo_irregular shape for walls
Draw a help line with parallels spaced apart equal to the thickness of the wall

It is better to have it a little bit more like thickness+0,2 meter to be able to put windows.

 03_Curved walls and ceiling in DIALux evo_irregular shape for walls
Go to storey and building constriction tool and move the other wall points to the new location of the line  04_Curved walls and ceiling in DIALux evo_irregular shape for walls
In 3d view of the storey (not the room)

Start a cut-out in the wall to follow the shape you are looking for ,

You can draw it randomly and modify it in the elevation.

 05_Curved walls and ceiling in DIALux evo_irregular shape for walls
Use limit cutting depth to be the same as the wall length.  06_Curved walls and ceiling in DIALux evo_irregular shape for walls
In plan view move the cutout line to the inner line of the wall.

To do this step you have to be in storey (not the room)

And cut out tool should be selected to be able to move the cutout.

 07_Curved walls and ceiling in DIALux evo_irregular shape for walls
The curved wall is made!  08_Curved walls and ceiling in DIALux evo_irregular shape for walls
 you can modify the points by right click of the mouse to delete or add points in the side view 09_Curved walls and ceiling in DIALux evo_irregular shape for walls
You can also create help line to help of the required shape in the elevation and then move the point of the cut-out the to help line.

This could be easier in case of curved line.

 10_Curved walls and ceiling in DIALux evo_irregular shape for walls
The more points you put the smother the curved wall is.

Remember you can only modify the cutout in the cutout tool.

 11_Curved walls and ceiling in DIALux evo_irregular shape for walls
Now you have a curved wall!

remember to have window the thickness has to have more +0,2 meter deep.

 12_Curved walls and ceiling in DIALux evo_irregular shape for walls
Making Curved ceiling
For ceiling insert a ceiling and make the ceiling thickness as the maximum depth for the final shape.  13_Curved walls and ceiling in DIALux evo_irregular shape for ceiling
In the 3d view of the room

This time should be the room not the Storey

Make a random cutout in the ceiling

 14_Curved walls and ceiling in DIALux evo_irregular shape for ceiling
You can modify the shape in the elevation view similar to the wall steps mentioned earlier  15_Curved walls and ceiling in DIALux evo_irregular shape for ceiling
Once you insert lighting it will be placed in the correct height  16_Curved walls and ceiling in DIALux evo_irregular shape for ceiling
Now you have curved ceiling!  16_Curved walls and ceiling in DIALux evo_irregular shape for ceiling

Creating Dropped Ceiling 


 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_05 Make sure you are on constriction mode


DIALux_evo_Ezzat_Baroudi_Tutorrial_4_06 Go to reference line tool
 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_07 Select a line
 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_08 Select a room cad view NOT STORY and make sure you are in Floorplan view

 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_09 Draw a reference line in the room form point 1 to 2 and make the offset line to be 1 m in the PARALLELS SPACED APART.

Tip: if the line is outside the room you can rotate along z axis 180 different than your current angle.


  1. Go to Ceiling Tool
  2. Click inside the room to select the room
  1. Draw new ceiling following points 1,2 (points at the offset reference line) then 3,4 and last right click the mouse and select close polygon.
 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_12 Make sure to put theClearance height = 3.25ceiling thickness=0.75m0.75m of thickness to make it solid without void because you are going to use the cutout tool as you will see later

Creating a recessed track lighting system


 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_13 From reference lines tool draw help reference grid with distance of x,y as 1,1 m above the dropped ceiling




From reference lines draw polygonal reference line in the point shown in the side image.Then right click to close polygon.

 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_15 You can delete the help reference grid, and now you can see polygonal reference line clearly.


 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_16 This is the position of a track light system.Now create offset lines form the four sides of the polygonal reference line in the same way as you did step-3 with an offset value of 0.035 m so you have the width of a track like the next image


 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_17 go to 3d view
DIALux_evo_Ezzat_Baroudi_Tutorrial_4_18 Select cutout toolAnd draw a rectangular cut out in the dropped ceiling
 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_19 Draw a random cutout in the ceiling

Go to plan view and select the cutout you made, if you can’t select it then go to the Cutout tool and select the cutout.

Move the corner points of the cutout to the corner points of the outer reference lines by mouse.

Go to plan view and select the cutout you made, if you can’t select it then go to the Cutout tool and select the cutout.Move the corner points of the cutout to the corner points of the outer reference lines by mouse.
 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_21 While selecting the cutoutActivate the Limit Cutting Depthput 0035 m as depthThis is the depth of a the Track


 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_22 Now go to material tool


 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_23 Select a black color and drag it while pushing the shift key of keyboard and apply the color to the inner surface of the niche.


DIALux_evo_Ezzat_Baroudi_Tutorrial_4_24 Go to plan view and make another ceiling in the corner of the inner reference lines.


Put clearance height as 3.25 and ceiling thickness 0.75


 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_26 Go to color and pick the color that you used by selecting the pick material optionsThen apply it to the four sides’ surface of the new ceiling.

 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_27  DIALux_evo_Ezzat_Baroudi_Tutorrial_4_28 Now you should be having niche in the ceiling similar to a reassessed track lighting system

Of course you could do the above by many different ways like objects and subtraction, but this way is very useful when you place lighting as DIALux detects ceiling and place the ceiling luminaires right at the ceiling!

Inserting furniture and objects


 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_29 Go to furniture and objects tool and select DIALux evo object catalog
  1. Put  in the search box the word 200×80 a legs
  2. Select the object that appears
  3. Click apply and close


DIALux_evo_Ezzat_Baroudi_Tutorrial_4_31 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_32 
select place individual object and place it somewhere in the roomMake the position at x=3,y=2 mHeight =0.35Rotation @Z=90°
 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_33 You can always use the mouse tool of modifying objects, which could be very handy if you have a cad background


Place a standard cube@position x=3m ,y=4.65 mSize L =0.3 ,W=0.3, H=1.3


Repeat the above for another cube with

position x=0.070m, y=2.9 m

size L = 0.140, W=4.2, H= 0.420


Insert another cube with

size L = 0.020, W= 0.800, H= 0.4 somewhere in the room, it doesn’t matter where as you are going to use it to create copies of it and delete it later, but make it near the left wall.


DIALux_evo_Ezzat_Baroudi_Tutorrial_4_35 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_36 Select the last cube and go to copy and arrange tool then select copy along line.If you are not selecting an object you will not see this option as active.

 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_39 Move the green arrow down to center of the cubeTip if you select the triangle then you can move in x,y plane, but if you select the green arrow you will move the object only in y axis.The red arrow will move only in x axis.For this tutorial move only the green arrow.
DIALux_evo_Ezzat_Baroudi_Tutorrial_4_40 After creating this object ungroup the parts


 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_41 Delete the object that was created in step-18 (used to creates these parts witch is selected in the next image)


 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_42 Make sure you are in the Copy and Arrange Tool, Select all the objects near the wall, and select center z to make the smaller objects and the center height of the bigger object.


create the last object which we use it as a painting on the wall

Place a cube with

position x= 0.025m, y= 2.55m, Z=1m

Size L = 0.050, W= 1.100, H= 1.100


Go to floorplan view and while selecting the last object use Ctrl+C and Ctrl+V to copy and paste the last object (you can also copy and paste by mouse right click )

The pasted object will be automatically selected, but should be modified to the following values

Size L = 0.030, W= 1.05, H= 1.05


 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_43 Go to front view  If you don’t see front view then click on the small arrowTip: use shift to select another abject and ctrl to deselect an abject

 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_47 Now you should be having a view like this one.

Importing 3ds and m3d files to DIALux evo


 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_48 In similar way to Step-3 ,draw 2 reference lines with an offset of 0.35 m form the table.the reference line will be the the edge of the table and the PARALLELS SPACED APART=0.35 outside the table.use rotation if the offset line is inside the table.Draw two lines, one for each sidefor each one like the next image, to place you can use this for imported chair in these locations.


Vitra Organic Chair  will be used in this tutorial


Vitra provide 3ds files for most of their products which could be imported easily into DIALux 4 and DIALux evo, however the file size should remain small in size with not too many surfaces, as rule of thumb try not to include a file more than 1 Mb,

This file has 208 KB which should be ok for most computers but if your computer specification is low then try to use lighter file, or use DIALux standard furniture.

The direct link to download the 3ds file for this chair is


you can also download form the following website


 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_50 go to DIALux Furniture and Objects tool and select DIALux object Catalog
 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_51 Once the catalog opens click on import button which is located at bottom left of the catalog
 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_52 Now click on add files and browse to the downloaded file of vita organic chair
 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_53 You Have To Select All Files While Importing 3ds files for version evo1, otherwise  you won’t be able to see the 3ds file


 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_54 Select the 3ds of the downloaded file


 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_55 Go back to the catalog (if the catalog is minimized then maximize it)

  1. Select the object in the right window by mouse.
  2. click assign
  3. click import


 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_56 Now in the search box of the catalog white organic, select the file and then apply, or double click on the object.


 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_157 Make sure the chair appears in the furniture and objects window.Select Draw line arrangment
 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_57 draw the line arrangement form point 1 to point 2.if you draw it from line 2 to 1 then you have to rotate it later(anti-clockwise)
 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_58 Put the quantity 2 and distance as 2


Repeat the line arrangement for chair for the lower reference line then Put the quantity 2 and distance as 2 for the second line.


 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_60 Move both arrangements to the center of the reference line, by selecting the red arrow


 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_61 If you select one of the chairs you select the arrangement where you can modify that arrangement, if you click another time on the same chair you activate selection of only that chair, then you can modify the object properties.
 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_62 Now select any chair twice to activate object properties and then select all other chair and modify the height to 0.675 m

If you feel your computer get slow in calculation download a liter chair form vita called Tom Vac, this chair has only 61.1 KB

The direct link is



 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_63 To replace all chair at one command select all chairs and then click on Replace selected objects, and then select the new object. Of course you have to import the new 3ds file first.


Go to http://archive3d.net to download flowers, this is a good website that has a lot of 3ds files, some of them could be used in DIALux which has small size and not too surfaces.

The direct link for the selected flowers for this tutorial is



Unlike Vitra 3ds made in meters which is perfect for DIALux, you find a lot of files in this website in different dimensions e.g. (mm, inches and feet)


 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_65 The current version of DIALux evo 1 doesn’t yet have an automatic scaling tool so you can use DIALux 4 to import and scale 3ds file and then save the file in m3d format.Open DIALux 4 and create a room of any size then go to file, import and edit 3d models.
 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_66 Select the downloaded 3ds flower file (Flower N171208) and then click next and select millimeters.Click next twice and finish.


 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_67 select the object and right click the mouse and select save objectSave object to a convenient location, let’s make it desktop and name it as Flower T4.


In a similar way to step-26 go to DIALux evo Furniture and Objects tool and open DIALux furniture catalog and import the files as you did in importing Vitra chair.

After importing write in the search box of the catalog the word Flower T, selected and apply, similar to step-17


 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_68 Go to 3d view and place the flower somewhere on the table, you can do this by dragging the flower by mouse to the table or by using place individual object and then selecting the location.


 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_69 Keep the flowers selected and go to copy and arrange tool, click shift and select the table so you have both objects selected.Click on center x, center y to make the flower vase center on table.


 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_70 let’s place the last object for this tutorial, go to furniture and object and select a sphere and make segments as 24 and diameter as 0.3


 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_71 Place it on the column created earlier


 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_72 Go to plan view and select the corner of the sphere to the corner of the column, this is a very easy way to move objects corners


 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_73 go to front view and move the z arrow of the sphere up to be at top of the column
 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_74 Now your project should look like the following image

Applying materials and colors


 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_75 Time to color your project so go to Materials tool

 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_81 Go to 3d view and Drag and drop theGrey+06 to the floorPalisander to table top and paining on wallGrass to the green color of flowers


 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_83 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_82
Make sure you are still in the materials tool and select the top surface of the table and rotate the surface by 90°.You can move scale and rotate the material as you wish.


 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_84 let’s import an image for the paining, this is the selected one for this tutorials.

 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_85 You can download then to Material tool, click on CREATE TEXTURE MATERIAL and browse to the image you want to import


 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_86 Select apply material and apply it to the front face of the painting object (alternately drag it while holding shift key down)


 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_87 Select the material on the painting and scale it to cover the whole painting.The points marked in red to scale.The point marked in green to rotate.The point marked in blue to move.


 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_88 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_89 let’s apply color to the rest of the surfaces by toing to Material Tool and selecting Create Color Material

  1. Adjust saturation to left so you can get a white color.
  2. Red, green and blue to high values
  3. Select Material type to be painted.
  4. Put reflection factor as 80%.

Note: 80% is very high don’t use this values for walls unless you are really sure as this value affect the calculation drastically

The default values in practice is 70% for ceiling, 50% for walls and 20% for floor


Apply this color to the ceiling 3 parts, walls, column, sphere and the 6 parts of low cabinet under the paining.
DIALux_evo_Ezzat_Baroudi_Tutorrial_4_91  DIALux_evo_Ezzat_Baroudi_Tutorrial_4_92  DIALux_evo_Ezzat_Baroudi_Tutorrial_4_93  DIALux_evo_Ezzat_Baroudi_Tutorrial_4_94

Light Calculation


DIALux_evo_Ezzat_Baroudi_Tutorrial_4_133 Time to calculate your project, so go to calculation mode


 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_134 You can start calculation right away but for this tutorial you will learn how to modify control groups and light scenes Go to Light Scene Tool in the CALCULATION MODE


 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_135 DIALux evo create by default each arrangement as control group, but you can change this anyway.Select the first control Group; it will be the RGBW wallwasherIf you canot see the control group click on the arrow heighted in Green box.The orange box shows you how many you have of this luminaire.You can click inside the red box and change the nameYou have four values as this luminaire has four color of RGBW (Red, Green, blue and warm white). You can dim any value from 100% to 0% before or after calculation.


 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_136 Keep this control group as it is and keep the group of 6 downlight as it is as well, but delete all other groups by clicking on the x on top right corner of control group window.


 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_137  DIALux_evo_Ezzat_Baroudi_Tutorrial_4_138 Go to Light scenes Actions and select Create new luminaire group and select the new luminaire group which should have 0 luminaire.Select all track spotlights then click on + icon on control group window to add those light to this control group.If you want to remove any of them you can select any spotlight and click on – icon which will be activated only if you select an added luminaire to the group.


 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_139 Name you light scene to be all Light on


 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_140  DIALux_evo_Ezzat_Baroudi_Tutorrial_4_141 Duplicate light scene form actions of light scene tool then name the new scene asWall washer Cyan ,50% Downlight


 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_142 Activate Wall washer Cyan, 50% Downlight scene by double clicking on the scene, if you wish activate Generate outputs for this light scene tosee values and results in the output.


 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_143 After selecting Wall washer Cyan ,50% Downlight scene, modify the scene to haveRGBW wallwasher Group Red=0,Green=100,Blue=100,Warm White=0Downlight Group=50%

Now you have 2 light scene, Remember you can modify these values after calculation, however if you would like to generate different results in the output then you have to create the scene you want.

Note: If you want to speed up the calculation time, then keep only one scene as we have furniture with many surfaces.


 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_144 Before you start calculation save the project in another name so you can have a backup file.Go to Calculation tool in the CALCULATION MODE and start calculation


 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_145  DIALux_evo_Ezzat_Baroudi_Tutorrial_4_146 You can show the different light scene by clicking on show once calculation finishes or form the top right corner select the required scene form the drop down menu and click on right icon to show it.


 DIALux_evo_Ezzat_Baroudi_Tutorrial_4_147 If the color appearance of the light looks unnatural, go to display options at the right upper corner and select white balance as manual.The white balance The warmer the color you select (values towards 2000) the cooler the appearance of the room you get and vice versa.Many people get confused thinking that 2000 should make the room very warm like the lamp values, that is not true 2000 means you are seeing the room too warm and software will take that factor to make it cooler.For this tutorial select a value of 4000K.

the tweets up to dates are

today the result DIALux Followers on twitter 164 Relux Followers on twitter 22

form Google trends-> people have searched for DIALux three times more than relux

I found Relux Has better library for 3d furniture and objects

in my opinion DIALux is much more intuitive



how many people liked the software on Facebook DIALux.support Page 6461 ReluxSuite Page 552

Relux has a very nice plugin for AutoCAD to create a room following poly lines


ReluxTunnel can easily calculate Tunnel DIALux doesn’t have any special calc for Tunnel

in a poll in my weblog most people (76%) preferred DIALux see details

As of today DIALux has 157 Partnershttp://www.dial.de/DIAL/de/dialux/pluginskataloge.html

the difference between DIALux evo and DIALux 4.10

DIALux evo beta has been released since a week  and many people are asking

Is generation 5 “evo” better than generation 4?

Actually DIALux evo is much more faster with better rendering, better handling of complex model and has different concept of construction, applying material, light and making the calculation.

Is DIALux evo ready to replace the current generation 4?

DIALux evo have not yet had all functions of DIALux 4

Daylight calculation, emergency lighting, street light and sport complex could only be done by DIALux 4.10 at the moment but will be implemented if future version of DIALux evo

if you want to see the result of  DIALux evo you can see my other post

My second complete project with DIALux evo Indoor and outdoor Project

My first project in DIALux evo 1

My second complete project with DIALux evo Indoor and outdoor Project

My second complete project with DIALux evo Indoor and outdoor Project

In this project I started to understand evo better, and I started to know what could cause the software to crash more than before which is very important for complex project with many surfaces and 3ds file

In the following project I used some 3ds files

  1. BMW X5
  2. Palm Tree
  3. Flowers
  4. Sphere to simulate ERCO Object “The square stele with sphere”

All other objects and materials have been completely made by DIALux evo, no other software has been used for modeling or final rendering.

Here are some tips for complex projects

  1. Try to minimize the control grope which are generated automatically by DIALux evo, you can reduces the number of control groups by going to calculation area and changing the control group.
  2. Try to minimize the light scene as well.
  3. Use low mesh 3ds files less than 1 MB  and you can first imported to DIALux 4.10 to change the size and converted to M3d then imported to DIALux evo.
  4. Save the DIALux evo file different times with deferent names e.g. 01, 02, 03…etc, to avoid losing the file and its data, DIALux evo will create a BAK file but this is a safer way to do it.
  5. Finally my advice to you , start with small project to understand the software before you start with a complex onet , remember that DIALux evo is completely deferent form DIALux 4.x.

here are some links that are useful to get some 3ds files and convert it to m3d files (m3d is a 3d furniture file format for DIALux 4.x and DIALux evo)

My first project in DIALux evo 1

My first project in DIALux evo 1

till the date of whiting this post DIALux evo 1 is still as beta version for some designers and I was lucky to be a beta tester for DIALux evo 1

Here is my experience,

My first impression was not very good about the new software as I didn’t know how to use it the way I used DIALux 4, and I was frustrated because it used to crash all the times and that was because I had my set up for the graphic system in cad  as openGL but when I changed it to Direct3D, most of my problems have gone, but still some bugs which I think hopefully will be gone in the future too.

Now I really find it great!! and start enjoying working in the new DIALux evo 1 a lot.

In my first project which is simple architecture for a small residence I made one complete story with 7 different spaces.

The result of the first room could be seen in the following images where I imported 3ds files (flower, planter,iPad, TV…etc) with texture and I made a cove light in the ceiling for ambient light and I used accent lighting as well.

The calculation is extremely fast compared to DIALux 4.10 with same complexity as it reduces the time from hours to only minutes!

Also the rendering is super fast compared to POV-Ray with fantastic result!

Hope you will like my first project
