SCRUG 9/21/2017 Making Money with Revit, Delivering the Promise of BIM

Sam Keville of Architects Orange was our master of ceremonies. A. Jay Holland had other matters to attend to.
Thank you to our sponsors... Kelar Pacific, Microdesk, & U.S. CAD. They provided pizza from Sgt Pepperonis Pizza, Cookies and drinks. 
Thank you to Little Diversified Architectural Consulting for providing the venue, hot drinks, wine and chilled water.
After introductions of new people, Ed Tallmage showed off the latest in tech from Leica Geosystems. His was one of  40 delivered thus far. This model connects wirelessly to the Apple Ipad Pro. It is lightweight and fast. Each scan taking two to three minutes based on whether you want hi res or low res. 
Sam jumped into the meat of his presentation. It was a throwback to the early days of #SCRUG when we had everyone exploring new features and sharing how to get things done.
With so many new comers he had to review some of the basics.

SCRUG 2/2/2017 LODPlanner

Through the miracles of changing schedules, I was able to attend this month's SCRUG meeting - the first in a long while. I estimate that about 60 people showed up.

It was announced on LinkedIn.
It was announced on Meetup.
It was detailed on the SCRUG blog.

After introductions & pizza, it went like this...
The main speaker Clive Jordan gave a bit of personal and BIMhistory.

In essence models progress over time. Like a painting that starts with one stroke & then becomes recognizable as more are added, a BIM begins with little geometry, accuracy, & information & becomes recognizable as a building information model.

Clive described how the terminology of BIM formed. Some familiar terms like... Level of *. Where the * could be any number of terms. Development, Definition, Information, Accuracy. While this LOD was meant to help in understanding, the splintering of terms has scattered meaning.

BIM=Data
The goal of BIM and LEAN construction is to get information where it is…
