Last modified: Aug 24, 2018

Installing the Lights Extension will equip CET Designer with many different light sources to pick from, everything from freestanding lamps to ceilings with integrated lights or fluorescent lights.

Below, each section on the Lights component tab is described.

 

Light Settings

  • In the Light Settings dialog, accessed by clicking the button on the Lights Extension tab, you can edit lights and groups of lights, and also set global lights. Which settings and options that are available is determined by which light source you are currently working with. To learn more about Light Settings, please follow the link to the Light Settings article.

 

Enable Realtime Lights

  • Checking the Enable realtime lights option will make lights sources update instantly as you work, letting you preview how they will change when you try out different settings.

 

Lighting Effects

  • Omni Light – a placeable component, a light bulb, that casts light in all directions but isn’t visible in renderings and can be placed anywhere in the drawing.
  • Rectangular Area Light – a placeable component that draws an illuminated rectangular area and can be placed anywhere in the drawing.

 

Ceiling

These two ceiling components have integrated lights, either fluorescent lights or a light wire grid.

To place one of these ceilings, follow these steps:

  1. Pick the desired ceiling component and move the mouse pointer to the drawing area.
  2. Click once to set a starting point.
  3. Start moving the mouse sideways to the desired width, or enter a measurement in the blue input box. Click to confirm the width.
  4. Move the mouse down to the desired depth, or enter a measurement in the blue input box. Click to confirm the depth.
  5. A new ceiling component is now placed on your pointer to keep letting you place more ceilings. If you do not wish to do so, move the mouse pointer outside of the drawing area or hit the Esc key to release the ceiling component.
  6. In the green input box that is now displayed, you can make settings for your ceiling.

In the Ceiling section, there is also a tool to reset the light, and a remover tool.

Selecting the Reset tool and then hovering with the mouse pointer over a ceiling will open a small blue input box in the upper right corner where you can choose to reset an individual light (Single) or all lights in the ceiling (All).

With the Remover tool, you can either click to remove individual lights, or draw a rectangle around a ceiling to remove all lights.

Note:

  • These ceilings default to being solid. This means that all light, including sunlight, is blocked and that the ceiling is solid both from below and above. To change this, select the ceiling and uncheck the Solid option in the green input box. The ceiling is now see-through from above but solid from below.

Custom Ceiling

These are tools that enable you to create a ceiling of any shape you like, with integrated lights and all.

To create a freeform ceiling, follow these steps:

  1. Pick the custom ceiling component and move the mouse pointer to the drawing area.
  2. Click once to set a starting point.
  3. Start drawing up the shape of your ceiling. Each time you click, a new point is added. Make sure to finish by fully closing the shape.
  4. A new custom ceiling component is now placed on your pointer to keep letting you place more ceilings. If you do not wish to do so, move the mouse pointer outside of the drawing area or hit the Esc key to release the custom ceiling component.
  5. In the green input box that is now displayed, you can make settings for your custom ceiling.

In the Custom Ceiling section, there are also tools for editing your ceiling:

LightsExtCustomCeilingAddPoint_70_eng Add point – adds an edit point anywhere along the ceiling’s 2D outline.
LightsExtCustomCeilingRemovePoint_70_eng Remove point – removes selected edit points along the ceiling’s 2D outline.
LightsExtCustomCeilingStraightCurved_70_eng Switch straight/curved – lets you click anywhere between two edit points to switch the line from straight to curved and vice versa.
LightsExtCustomCeilingSliceShape_70_eng Slice shape – lets you draw a line across a custom ceiling in order to divide it into one or more new ceilings.

Fluorescent Lights

The items in the Fluorescent Lights section are used for adding additional lights to ceilings. Therefore, you first need to place a ceiling. You can then go ahead and pick a light type and click it in place in the ceiling.

Other Lights

All other lights – Ceiling lamps, Sconces, Desk lamps and Floor lamps – are all standalone items that you can use as light sources or decoration in your drawings. Below are some examples of lamps that can be found here; some with a changed color or texture.
