When I attach a point cloud in Revit (2017), this message appears: The coordinates of the points in the point cloud file(s) you are trying to import are larger than 30000. When I perform a search for this message, nothing's found. Would be handy to know how to fix this. So my first attempt was to retrieve the origin of the point cloud. So I opened it in ReCap and there's a grid showing the origin. But there are no numbers. I.e. I can't get the coordinates of the origin. Next thing is loading the point cloud in AutoCAD. AutoCAD doesn't show a grid nor origin. So I just picked a point and noted it's coordinates. Then in Revit, I changed the coordinates for both Base and Survey point to reflect those I had looked up in AutoCAD. Next step is again linking the point cloud in the Revit project, using 'Auto - Origin to Origin'. Same message appears and the point cloud is nowhere to be seen. I ran out of ideas?

Hi @Simon_Weel
Did you check for the point cloud in the 3D view (zoom extents ZA)?
Does the model appear loaded in your status column in your manage links?
This issue happens due to minor scaling issues from the origin. Modifying the scale value is suggested if units of the source data have not been correctly determined during import of the point cloud file.
Let us know if you were able to resolve the issue.

Ah, that explains the scale factor. I wondered where that came from. Anyway, the point cloud is visible, although tiny - I thought it was a speck on the screen 🙂
But now for the real problem - does this message need resolving, or is it just a message?

Hi @Simon_Weel
Glad to hear that your point cloud is finally visible
If you can share a file (on the forum or through a private link) I can troubleshoot further. Let me know.

Hi @Simon_Weel
I just wanted to follow up here, any progress on this issue?
I've tested a point cloud in AutoCAD and was able to acquire the coordinates and imported back to Revit using origin to origin.
As mentioned before, if you can send us your model, we will be happy to test it for you. You can send the file through a box drive or post it here.Let us know if you have privacy issues with regard to sending your file.

What I did is what you suggested. I linked the point cloud in a new project, using "Auto - Origin to Origin". This places the point cloud about 400 km away from the project base point. Saved this project and linked it into the project used for modelling. Then moved this link to somewhere around the Project Base Point and aligned it with the model. This seems to work - more or less. Weird things happen though. It seems like the Point cloud has a mind of it's own, moving around without user intervention. I'm trying to figure out what's going on....

Hi @Simon_Weel
Good to know that you were able to align the point cloud with your model.
Can you elaborate on the weird things, do you get error messages or these are graphic glitches or the file is missing elements?
Looking forward to your reply update.

With the point cloud linked in a galaxy far, far away, it disappears from time to time. It's linked, but just not visible all the time. There's a message about weird graphic behavior when linking, so I guess this is one of those things.
I decided to try a different way. Modify the Revit Base Point to reflect the coordinates of the point cloud. After some digging, I managed to get those coordinates. At least, that's what I thought. A ReCap .rcp file is a ZIPfile containing a couple of bitmaps and an xml file. That xml file holds, among other things, the position of all .rcp files in the ReCap project. And it contains the camera location coordinates. There's a tag called <AutoCamCamera> and <AutoCamHomeCamera> of which I thought displayed the center coordinates of the 20x20 grid that's visible in ReCap. In this case, they actually did, but in a different point cloud they did not. Bummer.
So while the problem is solved for this project, I still wonder how to get the center coordinates of the grid displayed in ReCap as they define the insertion point of the point cloud in Revit.
