Hello,
We have recently finished a project scanning a factory, with a 120 stations.
Our customer wants to have pointcloud form each level from this factory. Each level is say about 20 stations.
Does anyone know a method to extract pointcloud from selections several stations ? (for example 1 to 20 stations from a total of 120) Before extract all the data.
Selecting more than 1 station in the scan explorer of Realworks won’t work.
The solutions i have come with is:
- Make a slice extraction with the scan explorer. This will give een extracting with the height of te level. Down side is that this solution, you can not control which stations you want to extract.
- Load all points of the project. Then go to registration and select the group with scans 1 to 20 and export. This solution is not very practical because we have to extract al the data.
With kind regards,

Re: Extract pointcloud
There are a few ways to do this that I can think of.
If there is no overlap of point clouds between each level, you could treat each level as a separate RW project and then export the project cloud as a whole.
If everything has to be in one project, then rather than exporting data from selected stations, I'd suggest that you segment the registered and unified point cloud to create a series of point clouds, one for each level, these can then be individually exported.
Hope that helps.

Re: Extract pointcloud
Hi,
Thank you for the answer. We thought about that same options you mentioned. Eventually the best option for us (and our customer) is to export a .E57 from each station in "Registration mode" (sampling = 2 step). After this we load each station file into Recap. Our customer has than the ability to select every station he wants in Recap and can use it in ACAD or REVIT.
When we directy export to .e57 in REG mode, we dont have to extract cloud from the scan explorer (which will be a huge dataset in HiRes)
Thanks for your help.
With kind regards.
