Topography from point cloud / recap file?!

[atis.sed]

Hi, 

is there a SIMPLE way to create Revit topography from point could (.rcp / .las) ? 

Just spent hour searching and the Autodesk solution is to install Civil3D (which I have available but CMON! to install software just for one function?!) 

Is there a way of getting .csv file from point could ?

Thankyou, but I don't see .XYZ file format in ReCap export settings.. 

[barthbradley]

Export to PTS file. 

[atis.sed]

And how do I import .pts that to Revit Topography points ? 

Even if I rename file extension to .csv, there are no points found when doing the import. 

[barthbradley]

Convert PTS to TXT. Revit can create Toposurface from TXT.

I tried that. If I change .pts extension to .txt, there are more than 3 columns and Revit does not recognize any points.

It also needs to be comma separated. Can't you manually format it in excel (e.g. convert it to CSV and delete extraneous data)?

So, to anyone who are in search for .LAS (with point classifications)  -> RVT topography:

The Autodesk method is to:

1. Install Recap,
2. save points as .rcp
3. Install Civil3D,
4. open .rcp in C3D, 
5. cut your region
6. filter by classification making surface
   1. Export to .dwg
   2. import in RVT.(this did not work for me)
   3. OR
   4. Install Autodesk Desktop Connector
   5. Link Civil 3D topography (which you probably cannot edit RVT because it is linked) (at this point I flipped my table and went with non Autodesk method)

The non Autodesk method:

1. Install free opensource CloudCompare
2. Filter points by classification 
3. cut your region
4. Save as ASCII.txt (comma seperated)
5. Import in Revit Topography Create from import points file.

And now I have fully function Revit topo with one additional software (not three as in Autodesk way (facepalm))

What's was wrong with what you showed in Message #7?  You couldn't extrapolate the x,y,z data? 

This is what I got from it.  Is it correct? I'm curious to know. 

   

[atis.sed]

There was point classification I needed to filter out, in my case ground points. 

Edit: I assume your result is correct but I can't tell for sure as this is small part of point cloud and points are unfiltered.
