Guide to Create Revit Topography from Point Cloud Data using Civil3D as a middle man

Luke Johnson

Mark Cronin has put together a nice guide describing how to clean up point cloud data in Civil3D, make a surface and then import that into Revit for topography creation.  This is an alternative to using ScanToBIM for topography creation from point data, and if you already have Civil3D it might be the better route.

SketchUp Pro 2014, IFC and BIM – what are the implications?

Luke Johnson

Some thought-provoking stuff from the shoegnome blog: 
“SketchUp was a disruptive force when it appeared so many years ago. It democratized and simplified 3D modeling. Anyone could model anything in SketchUp. And now there are 3.5 MILLION models in the 3D warehouse. SketchUp can now attach IFC data to elements. Connect those dots.
…
In 2014 SketchUp became BIM. And I think we’re all in for a whole new thing.”

ScanToBIM alternative for Sketchup Users? Trimble Scan Explorer Extension now available

Luke Johnson

The Trimble Scan Explorer Extension dramatically reduces the time required to generate a SketchUp Pro 3D model from scan data. Streamlined tools and one-touch features allow users to quickly extract construction points and lines that are used as a guide to simplify and expedite the modeling process. Automated plane extraction tools further increase modeling efficiency, particularly when modeling building interiors and facades.

Revit Zero is not the same as Project Base Point

Luke Johnson

Often, it is.  But if Project Base Point has ever moved in the life of the Revit project, then it probably won’t be.  Revit Zero (sometimes called the Internal Origin) affects things like FBX and NWC export (IFC too) when using Project Coordinates.

One way to find it is to make a DWG file with a couple of lines at 0,0,0 and link in Auto – Origin to Origin.  Another way is to make a Spot Coordinate that reports based on the “Relative” option.

You can theoretically  have 3 different coordinate records for a single geometric point, as this image shows:
