Segmented Point Cloud?

[Jason__M]

We're begining to look at Civil 3d 2016 from 2014.  We've been using PCG Point clouds indexed through Kubit and haven't used ReCap very often.  It looks like we will want to use ReCap more to be able to take advantage of the new features in Civil 3d.  In the Civil 3d 2016 list of new features they describe being able to "infer geometry from a segmented point cloud".  They describe segmenting point data in a point cloud as something that ReCap does.  When I search the ReCap help section for the word segment I get a link to some video that does not describe creating segmented data. 

Does ReCap 2016 segment the point data or do we need ReCap 360 or Recap 360 Ultimate to do this?

Where can I find information about segmenting the point data?

Thank you

Structured laser scans are segmented by default in ReCap. You don't need ReCap360 or Ultimate.

AutoCAD will automatically detected whether segmentation information is available or not in the .rcs files.

Does it make a difference what files are used to create the .rcs files?  When using Kubit, we typically created an .e57 file that we indexed to a .pcg file.  In our tests with ReCap we were indexing the same .e57 files.  As our scan data is captured and registered with FARO Scene, should we be indexing a .fws, or the .lsproj files?

Thanks again,

I would start a new Recap Project, then try the scenario with adding the FWS files. Just Add 2 or 3 files, scip the indexing in the import macro and then save and close the project.
Reopen and take a look at it, when it's good, then import all the other fws files.
It DOES help to speed up things when you copy the fws files and save the Recap Projcet on a local SSD drive.

I see now that my data was segmented (it shows up in the properties in Civil 3d).  I was trying to see Civil 3d 2016's feature extraction (spefically finding the centerline of a cylinder).  It seems like the data I was using was maybe too noisy and that's why it seemed like it wasn't seeing anything working.  Thanks for your help.

Hi Jason

How Were you able to infer centrelines of cylinders?

I too am the same.  Properties shows it is segmented.  However I don't seem to be able to infer.

Thanks

Hey everyone,

I noticed that snaps don't work if the point cloud was unified in Recap or registration software. Works fine on ununified data, just slow to move around on a big data set.
