Jed, Stefan thanks for your comments. I have now deleted all data behind windows. I did notice the image turning black in planar view so just re-applied pictures. I'm now wondering whether to remove all glass surface points as well, effectively removing glass altogether to make a hole, because the scanner picks up the surface of the glass only in places which is correct however it looks a mess because it's very patchy.

Actually, in 5.4 (& 5.3 I think), the RAWSCANS folder is created, but is empty if you answer no and then drag the scan folders into your project.
I think under 5.2, the raw scans would get the .fls files from the first save. In 5.3 & 5.4 they go into Revisions\1\Scans if I'm not mistaken.

===============
Caesar, If you use the dialog Scene prompts you with to import scans from SD card when you plug one it, Scene will automatically create a folder called "RAWSCANS" and copy the originals to this directory will they will remain untampered with.
AND from the SCENE user manual "Clicking yes will import new scans from the SD card and create a local copy of the automatic scanner snapshot. The local copy of this automatic scanner snapshot can be found under the folder Scanners in the Structure View of the scanner administration and bears the name of your scanner's serial number."

David,
I totally agree! It's a boring and time consuming way! I like the Recap, Cyclone and CloudCompare tools for cleaning, but I found no way back to SCENE :(

I think, it would be worth to write an app, for cleaning points outside an imported model. Someone interesting in writing one?

Import from SDcard: never tried this, because most time my cards are full with different projects. Never have all projects on my PC or Notebook. And SCENE did not allow to choose the project it should import, it imports the whole card every time. Wished it would remember which was imported earlier (I often move projects from one PC to another and use the SDcards for backup)

Greetings
Stefan

I hope that makes sense :)

Yes it does ! - I am given the scan data to download from an FTP so I need to manage it all manually.
I was always wondering what the RAW SCANS folder was for when you create project. So its good to know I can drop the scans there. What I am gathering is that scene will make a copy of the scans in that folder in order to keep them intact.

I just caught up with all the responses.
Thank you guys.

So from what I am gathering is that as long as I copy the scans into the rawscan folder, scenes know to keep them unaltered and saves copied under revisions. I am going to speculate that when I do a "cleanup" on the project i will delete of the revisions but still keep the original scans.

You guys have been great help.
It funny what a big difference it makes when you understand/know the software and what you are doing versus just hacking it and getting by. I even opened some of the Asus Xtion scans I did which were a mess and I was able to create scan point clouds and use clipping boxes to clean them up. Now if I could only find a way to orient them right side up etc. Can someone with experience in this give a hand ? (I know this is not the right thread )

Hello Cesar,

in SCENE 5.4 / SCENE Process/Capture there is a levelling tool for easy orientation of point clouds that don't have inclinometer information. In older versions I fear you will have to manually play around with the transformations...

Best regards,
Joachim

I don't want to start a new thread but I'm curious how the version 6 handle the workflow ? If I clean the SPC (delete points) and later create the PPC will the data still come from Raw scans ? Does your workflow change (and how if any) within the Scene 6 ?
thanks!

Hi!

Whenever you edit SPCs and save the project, the corresponding (raw) scans will get updated and the SPC re-created. This behavior is the same for SCENE 5 and SCENE 6.
The PPC will then get created from the raw scan with the updated data, but of course you need to save those updates to the scan beforehand.

Best regards,
Joachim
