Create light strips quickly and easily

You can now place the luminaires either by the number of luminaires in X and Y direction of the field, or by the distance between the luminaires. Light strips can thus be created very easily and conveniently, and there is no need to use a pocket calculator to recalculate. At the beginning of your planning, the number of luminaires is determined as the planning objective using the light output ratio method, with the minimum illuminance levels required in the room profile Three options are available for the start position of the first and last luminaire:

  • Half the distance from the edge of the field to the first luminaire for a symmetrical distribution within the field
  • The first luminaire at the edge of the field
  • The first luminaire in the middle of the field edge

You can adjust all field parameters before, during and after drawing. 

The size of the field arrangement, the distances between the luminaires and the angles within the field arrangement are displayed directly in the CAD. The dimensioning between the luminaires is carried out either from luminaire edge to luminaire edge or from luminaire centre to luminaire centre.

All grid lines can be moved manually and adapted to the conditions. Individual or all grid lines can be fixed in position.

When you draw a field arrangement, the alignment of the field is determined dynamically. It is therefore no longer dependent on the character sequence. While you are drawing, a preview of the luminaires and grid lines is displayed so that you can get an immediate impression of the placed luminaires.

 


Planning luminaire fields also on slopes

We have also worked on making it easier to use guide lines for luminaires that are oriented towards sloping room boundaries. On the one hand, the guide lines are now activated separately, so that confusion with the field polygon is no longer possible. Furthermore, the guide lines can now be placed freely in the CAD. This allows you to align the lights on any edges or lines. It is now also possible to exchange individual luminaires within the arrangement in order to place mixed luminaire fields or to use luminaires with special properties at individual points. Several field arrangements can be edited together, for example to change the luminaire distance at several positions in the project together.
 

Patch

—  You can apply textures to 3ds objects again
—  Lights and furniture can be selected together again (and now also grouped)
—  An error in the GR calculation was fixed
—  We have reduced the standard quality for images in the PDF export from 100% to 80% to reduce the file size without visible quality loss
—  The project-wide luminaire parts list is back
—  Also for GR-areas you get now again charts in the documentation
—  Fixed some problems with the DWG import
—  Header and Footer can be set as standard for future projects
—  In the street documentation, decimal places are no longer incorrectly always given as 00
—  A bug in the OpenGL shader was fixed
—  Various other bug fixes and improvements in geometry generation, project loading and documentation


New output design


The documentation of the project will have a completely new design with a new layout: 

—>  The font will be larger, and images and cover pages will be visually more attractive
—>  Contact details are on a separate page
—>  The disclaimer and the imprint can also be edited individually by the user

Furthermore there will be a complete room overview in the documentation listing all the rooms with their respective luminaires and energy data, it is no longer necessary to create outputs for each individual room.

 

New calculation method: Faster calculation and better visualization of complex objects


The previous calculation method (photon shooter) is enhanced by a process which takes detailed objects into special account. This is not only of benefit for the calculation speed and subsequent adjustments of light scenes but also leads to a general improvement in the presentation of detailed objects with many surfaces in CAD. Unlike the results achieved with the setting »Simplified illumination of furniture and objects«, with this enhanced method the lighting effect on the object surfaces should be displayed as realistically as possible.


Revised luminaire placement and snap function


We have revised the light lines and the snap mechanism for you. This will save you a lot of time with your light placement. We have added the following new features: - In the CAD you can see dimensions, the construction direction and a visualization of the luminaires to be placed - Luminaires can be distributed along the line either by number or by distance - We have revised the snap function for you, new features include the length grid and the angle snap.


Simplification for planning light in outdoor spaces


Previously there was no specific information in the navigation bar for outdoor spaces only and no specific view for these in CAD. This will change with the new version. We extended the navigation bar with a view for outdoor spaces. In addition it is also possible to visualize the contours of indoor and outdoor spaces during your work.
