Utilizing Coordinates To Link In Point Cloud

Hi all,

 

I am new to the point cloud world and I am trying to link in a point cloud I registered and applied control points to already in Register 360.

Here is my workflow this far:

  1. Revit model has its coordinates established from civil base

  2. I import the point cloud using shared coordinates.

  3. Point cloud aligns in correct location - pin it and save.

  4. When opening the file after exiting the point cloud has disappeared, so I go to my manage tab and reload it and the point cloud has totally shifted from the established coordinates.

 

Has anyone ran into this problem before?

 

As a side note, my .rcp file has be exported twice, once from register 360 as an .e57 file and second export is from recap to export as a recap file to load into Revit - I was told that register 360 cannot export and .RCP file with over a million points so that is why I am double exporting.

 

I appreciate all your help!

I don't see an issue with the workflow.  Should be there upon reopening. 

 

Alternate workflow: instead Linking the PC directly, place the PC in its own RVT and then Link the RVT/PC into the Host and set up Shared Coordinates between the Host and RVT/PC.

I have tried that as well and I am having the same issue of the point cloud disappearing and when reloaded the point cloud has shifted.

 

I think the issue is stemming from exporting as .e57 then importing into Recap to export again. Is there any way around this with your point cloud has over a billion points?

 

With a smaller point cloud I was able to export as an .rcp directly from Register 360 with control applied and the import into Revit was successful. When I reopened the file the point cloud was there and still position in the correct place.

1. You need to split into several scans 

2. You need more than 3 control points (the more the merrier applies in large scans)

3. When we have Xlarge scans we from Recap we import and set out in Autocad before bringing to Revit
