How to create a cove light detail In this tutorial you will learn the following commands.

1. Using help lines 2. Using ceiling. 3. Using cutout 4. Using Boolean operation 5. Some other command

There are two types of cove light in terms of light distribution inside a room

Outside cove light that distribute lighting to the walls Inside cove light witch distribute lighting to the room

Outside cove Inside cove

How to create an outside cove


2

Using help lines For this tutorial let’s say that we don’t have a cad drawing, but you know the offset form the wall of the cove which is 500 mm all around the room.

1. Make sure you are on construction mode

2. Go to help line tool (2). 3. Select line command (3) 4. Draw the line at the boundary of

the room form one corner to another (4)

5. Set the offset as 0.5 m form parallels spaced apart (5). You can make many lines but for this tutorial we need to keep it 1.

6. If the second line is place outside the room rotate the line to be inside the room, alternately make the offset value in minus (-0.500 m).

7. Repeat the previous steps to have 4 lines around the room. Tips:

You can also you grid help line and set x,y to 0.5 m each.

If the cove is round you can select a circle help line.


3

Now the boundary of the cove is created by the help line the next step is to create the cove Creating the cove Go to ceiling tool and then click the left button of the mouse in the room to select the room, and then select draw new ceiling command as illustrated below


4

Draw the ceiling by click the left mouse on the four corners of the cove boundary and then right click to select CLOSE POLYGON

Now a new property window will appear while the ceiling is selected

For this tutorial, the value of the false ceiling will be same as default values; however the side offset will be 0.25 where we can use this space for luminaires.


5

Tip: use the CTRL+T to open a new tap where you can keep one tab for plan another for side view and may be another for 3d view.

Now the cove is created as you could see form the side view

We are missing the edge of the cove. Creating the edge To create the edge you can place a cube and scale it to the required diminution

Select the depth to be around 15 mm (0.015 m), the height is 150 mm (0.15 m). For the length you can put it directly or use the scale tool


6

Now align the four edges to the cove

1. Go to copy and arrange tool. 2. Select the edges and the cove. 3. Align to top. 4. Align to bottom. Tip: If you align to bottom without the step 3 then the cove will get to lower level.

Adding cove lighting.

Go to LIGHT mode Select the luminaire and then select a line draw the line form one point to another


7

Put the quantity as required to keep the luminaries in a continuous arrangements. Tips

You can click on the arrows to see more options of position and rotations.

ARRAIGNMENT: allow you to choose the distance to be between center to center or edge to edge etc.

ROTATE: allow you to quickly and easily rotate the luminaires.

Go to DISPLAY OPTIONS in the right corner of the software interface and activate Show Light Distributions Curves. Select the luminaire to see if the light is going up to the ceiling or down.


8

It the light is going to the floor rotate the light by clicking on the arrow of rotation and rotate 180 degree on x or y

After rotation make sure the light destruction is changed to ceiling.

Move the luminaires to be inside the cove up. Tip: Select the blue arrow to move the luminaires only in z direction. If you select the green triangle then the luminaires will move in more than one axis.

Copy this line to the other area and modify the quantity as required Changing the color temperature


9

1. Make sure you are in the LIGHT mode.

2. Go to lamps and select all the luminaires you want to change.

3. Go to correct and click on the word CORRECT.

4. Select the lamp type of the color temperature.

5. Select the value of the color temperature.

It is VERY IMPORTANT to click on apply otherwise nothing will be changed

Start calculation

Creating inside cove

Go to ceiling tool and then click the left button of the mouse in the room to select the room, and then select draw new ceiling command as illustrated below

Keep the same value as default.


12

In the plan view create a grid help line with 1x1 meter; draw the grid form point 1, point 2 and finally point three as illustrated below.

You can always rotate the grid after you finish it. Form the property window in the upper right, but now you don’t need to rotate if you draw in the order shown above.


13

In the 3d view go to cutout tool and select rectangular cutout and draw in the false ceiling in 3d view as illustrated below

Go to plan view and edit the cut out move the cutout to be 2x3 using the grid help lines


14

Go to 3d view and see the shape it should be similar to the one below

Tips

If you the cutout selected you cannot see the details change the tool to a different tool to be able to see clearly.

Change the color for the apper part to see the details.

Now you have a cut out but no edges


15

Creating the edges

Insert cube and scale it to cover the cut out area, make the height 0.15 m which is the height of the edge.

Copy the cube or insert a new cube and make it bigger by 30 mm in x and y 30 mm to allow for 15 mm which is the thickness of the edge.

1. Select both objects and go to copy and arrange tool

2. Click on subtract tab 3. Select the object to

remain. 4. Look at the view the

object to remain should be in dark red

Click on subtract button.


16

Insert anther cube with a dimension bigger than the cutout opening by 250 mm form each side, the x,y of the cube will be 3.5, 2.5 m respectively, the height should be 0.3 m

Create another cube bigger than the last cube by some value, it dosent matter the value but should be bigger thencut the last two cubes to keep the bigger one as a boundary, make sure the red is the outer one

Now you have the edge and the back boundery of the luminaires as in the next image


17

You can combine both objects by copy and arrange tool and then combine tab combine

Move the combined object to the ceiling

You can align the object to false ceiling by using align command in the copy and arrange tool.


18

Add the luminaires as explained in the outside cove and start calculation.
