Using a DXF to Locate a Point Cloud in Revit with Very Large Coordinates
Using a DXF to Locate a Point Cloud in Revit with Very Large Coordinates I thought that most of this was easy and solved now, but it was more of a challenge than I expected. I received a ASC file from a survey in XYZRGB format, which looks like this: Those XYZ values are Metres (or Meters if you are in US) in the MGA 94 coordinate system. I also received a DXF file with the same World coordinates, and project related gridlines so I could relate the point cloud to our Revit models. I tried getting the MGA Shared Coordinates right in Revit, and then linking an RCP or RCS from Recap by Shared Coordinates, but I didnt have much joy. Here is the workflow that worked for me... Getting the right Shared Coordinates in Revit Start a new, blank Revit model Link the DXF Centre-to-Centre (this is best way to deal with huge coordinates) Acquire Coordinates from it Save your Revit file. You now have the right World coordinates, and a project grid relationship. Importing the Point Cloud by Shared Coo...
