Take a hand sketch, for example – how can you get that into a format that can easily be used in AutoCAD or Revit? Some PDFs have vector information, which I have described how to access before. We often have to deal with data that hasn’t always “lived” in our CAD, BIM or Revit world. In Revit, L ink Point Cloud, by Sh ared Coordinates, and choose the un Indexed r aw PCG:.But PCG is a nice reli able cont a iner th at supports colours. For the ASC d at a above, on the import sett ings I used ‘ Adv anced’, and chose the text columns XYZRGB. Import ing the Point Cloud by Sh ared Coordinates You now h ave the right World coordinates, and a project grid rel ationship. L ink the DXF Centre- to-Centre (this is best w ay to de al with huge coordinates).Gett ing the right Sh ared Coordinates in Revit Here is the workflow th at worked for me… I tried gett ing the MG A Sh ared Coordinates right in Revit, and then l ink ing an RCP or RCS from Rec ap ‘by Sh ared Coordinates‘, but I didn’t h ave much joy. I also received a DXF file with the s ame World coordinates, and project rel ated gridl ines so I could rel ate the point cloud to our Revit models. Those XYZ v alues are Metres (or Meters if you are in US) in the MG A 94 coord in ate system. What Revit Wants: Using a DXF to Locate a Point Cloud in Revit with Very Large Coordinates GIS dxf, emeditor, point cloud, recap, Shared Coordinates No Comments Hope this helps you if you face a similar problem ? Now you can Acquire Coordinates from the original DXF and you will have reinstated the ‘world coordinates’, but the Revit point cloud rendering engine is now much happier.You may need to temporarily neutralize coordinates ( here or here), and….Link in the original DXF and align it with the modified temporary DWG we were using.Everything lines up now that the large coordinate shift error has been avoided!.Link the Point Cloud RCP By Shared Coordinates.
Link this modified DWG into Revit, Center-to-Center.Save As – a new DWG file with modified coordinates. Move the objects by the values above (278100, 6121000) towards the origin. Open surveyor DXF file in AutoCAD and manually Move all the geometry.Index a new RCP in Recap using the simplified data.Ok, with the simplified source data in hand, I followed these steps:
