Hi Wesley,

 

this file contains 4 components that are no part of the standard set:

 

Analysis Points

DIVA analysis

Material

Solar Vector

 

I do not have these installed and therefore those 4 components fail to load. If you don't have this component library anymore then you won't be able to open the file correctly. Re-install the library and you should be fine.

 

The "Object reference not set to an instance of an object." errors, are not a big problem. These errors will disappear once the solution is all hooked up again. They shouldn't have happened to begin with, but they are symptoms, not causes.

It's DIVA  - I can confirm that the definition opens fine as long as you have DIVA installed.

Hi Andrew,

 

Out of interest what's DIVA when its at home? I cannot find any mention of it on Food4Rhino or the Add-ins page here.

 

EDIT: Never mind Google has all the answers.

Hi Danny,

 

DIVA is a GH plugin by Jeff Niemasz linking it with Radiance.

Radiance is a free daylight analysis software which is known to be more reliable than Ecotect (heard this from an engineer in the field).

It is not an easy plugin as you need a specific grid to output to Radiance, please let me know if you manage to make it work. I ended up exporting manually to radiance during this workshop.

 

Hope that was more personal than google!

Thanks Arthur.

 

I realise that some people are going to be reading these posts after translation and hopefully I can prevent them going mad by way of explanation of certain colloquial phrases and at the same time broaden the horizons of others :)

How can you tell what the missing components are?  This would be super helpful since I seem to get this error a lot when opening scripts...
