Daylight Visualiser

At the moment I am contemplating putting a small extension on the back of my house. As you can imagine I modelled this in Revit, it would have been wrong to develop it in anything less. :-) But whilst I was looking for a Velux Revit window family I came across this….

BTW the families on the Velux website are very poor; instead go to the BIMstore you will find some very good Velux families which actually work rather than a dodgy DWG import. Why do manufacturers still continue to do that?

Anyway, to better understand lighting I tried the Velux Daylight Visualiser. Daylight Visualiser works for Mac & PC. I created a separate export 3d view in Revit, limited just the geometry I needed & exported as a DWG 2007.

imageI was then able to import this into Daylight Visualiser, setup the location, apply some simple materials, setup the time of day & render away. It works well, its reasonable quick & quality is good. So after a few hours of rendering I managed to knock a animated lighting analysis which was good enough to understand the lighting impact on the extension.

What happened to Project & Shared

Paul Woddy & I picked up this when we were at AU2012, whilst helping out in a labs class, it seemed to elude us & maybe a few others as well. It relates to the naming protocol of Elevation Base parameter in Revit 2013. As far as we could both remember, up until Revit 2013 your  Elevation Base constraint parameter was either Project or Shared. The image below is from Revit 2012.


The Revit 2012 help describes Elevation Base as follows.

If the elevation base value is set to Project, the elevation reported on a level is with respect to the project origin. If the base value is set to Shared, then the elevation reported is with respect to the shared origin. To change the shared origin, you can relocate the project.

Now lets see what appeared in Revit 2013! For some reason the Elevation Base Point parameter names have changed. I can see why this has happened, maybe for consistency with the away you approach shared coordinates & levels, Neither  the less naming is confusing! Why point? When architects talk about a height, typically we talk about a level, not necessarily a point.


The Revit 2013 helps describes Elevation Base as follows:-

If the elevation base value is set to Project Base Point, the elevation reported on a level is with respect to the project origin.

If the base value is set to Survey Point, then the elevation reported is with respect to the fixed survey point.

At the end of the day, its not a big deal, but these minor changes need to be watched for.

So today CASE Inc in collaboration with SOM launched AEC-APPs. Think of it as a social community driven site for the AEC industry to share technology tools & solutions. Its free to sign up, upload your favourite apps, rate them, rate others, discover what others are using. A one stop shop for the AEC professional looking to expand there BIM capabilities through the use of new technology.

AU2012 video + sound

AU2012 is over for another year, the key take homes included formit, BIM360, Fusion360, Cloud, BIM, more BIM & more Cloud. So rather than boring you with stuff you can find else where, find below a nice video of the trek from the room I was sharing with Don Rudder at Luxor to the Mandalay Bay AU2012 catering facilities! :-)
