Cant see pointcloud in revit

Hi guys,

 

I need some help inserting a point cloud. 

 

I have received a Geo-referenced Point Cloud in RCP format. With the real world coordinates.

 

When i insert into Revit, of course i want to use origin to origin. However, when i do this the pointcloud is inserted very far, and i cannot find it.

 

If i use center to center then i can see it, but the coordinates are wrong, and i dont want to have to update them everytime. 

In autocad it zooms to the cloud, but in revit i cannot find the solution...

 

Can anyone help me find my pointcloud!!

 

Thanks!!!

Geodetic coordinates are great for surveying and civil work, but not for mechanical design - even with large buildings.  Have the surveyor re-register the point cloud to coordinates you provide.  Provide them with a set of drawings, site photos, and whatever else makes your intentions clear.  Mark them up with several locations clearly marked with coordinate values you want to use.  Pick points that are both easy find in a point cloud (like the corner of a foundation) and that are critical to your design.  You'll want to provide at *least* 3 points, preferably at 90 degrees to each other, and spaced as far apart as possible.  With that information the surveyor can transform the point cloud in both scale, position, and orientation to those points while minimizing error.

 

Its usually a good thing to indicate this when requesting the scan.  Not only does it minimize the back-and-forth ("You didn't say you wanted that" "Well, how was I supposed to know?" "OK but I'll need to charge extra" yadda yadda...) but its helpful for the surveyor to know critical areas that *must* be scanned so they don't have to go back to site.

I'm having the same problem. We're currently in the process of moving from AutoCAD to Revit. I am shocked at how badly Revit handles point clouds...
