At the time I submitted the abstract, I was also wondering if in fact groups were the best solution for my purposes, and part of my research preparing for the conference was to test alternatives. Before I started the research, I wondered if my presentation might end up being about something other than groups – something along the lines of, these are all the things I found wrong with groups, so use assemblies!
As you will see from the slidedeck this was not the case. Whilst groups are error prone and seem to have a lot of bugs (Autodesk are you reading?), they are still the best available solution within revit for collecting together repetitive sets of objects.
The presentation is essentially structured to be your guide to many aspects of using and troubleshooting groups. I see it as a great training resource for all levels of revit users from fairly new to experienced. The slidedeck explores many different ways of using groups, exploring the full functionality of exporting, importing and detailed annotation groups (which is incredibly powerful), how to vary and schedule groups and how to deal with errors. I spent over 6 months gathering screen clips and trying to solve various group errors, and along the way found many to share.
However, even I found something new to learn about groups at the RTC. Aaron Maller, who in my opinion is the guru if groups (I learnt much of what I know reading Aaron’s blog and forum posts) – was also presenting a session on groups. Whilst we covered some of the same topics, there was a lot of different tips from his presentation. In particular, I don’t use face based families, and it seems there are a lot of issues with face based families and groups. If you want to know more about errors mirroring, flipping and rotating groups check out Aaron’s presentation (if you went to RTC it’s on the app). Apparently you can’t rotate a group with face based objects 90 degrees, 87 then 3 is fine though!!!
Another great RTC is over (it was the sixth time I have attended), but I’m not quite done with RTC for the year yet – today I fly to the USA where I will be presenting at RTCNA in Chicago (19-21 June). I am part of the “BIMinions” lineup and we are presenting a session entitled BIMx: Big ideas around big data. My own presentation is called Big data at the intersection of building analytics and people analytics. Hope to see you there – 2.30 on Saturday afternoon. You can also keep up to date with all my RTC tweets @BIMinions.
See you again in early July when I will share my Chicago talk – which is a very interesting mix of workplace design issues intersecting with BIM – I have had a lot of fun researching it, and look forward to sharing it with you soon.
