Laser Scanning and Revit - What you NEED to Know

On this episode of BIM After Dark Live I am excited to have Matt Stachoni on as a special guest to talk about laser scanning!

I tend to get quite a few emails about either the process of laser scanning and creating a model from it or the process of using a point cloud in Revit. Matt is an expert in the area of laser scanning and is overseeing the scanning of a $1.5 billion airport project here in the Northeast... Yeah, that's a lot of scanning...

Whether you are interested in getting into scanning yourself or find yourself using scans, this will be a must watch episode!

Some of the topics we will discuss (on top of your own questions!):

Laser scanning basics:
- Quick description of technology
- Typical classes of scanning hardware
- Resolution settings
- Targets / Registration

Use Cases:
- Historical Preservation
- Construction

Budget / Planning:
- Laser Scanning Execution Plan
- Scanners, People, Computers
- Typical Scanning Workstation Needs
