I’m doing Isolation and Overlap detection after fusing and sometimes Revoscan wants to delete something I don’t want to delete.
Is there a way to deselect areas in the these tools?
Not really , the lose points removing everything what is lose and not attached to the main scan . You can lower the size fragment to 1 % if still not working just go with the overlapping detection and after meshing you can remove again the lose points.
Overlapping detection removing only overlapped points not scan fragment
Lose points detection removing lose fragments.
Sometimes when I scan objects that are not really connected to each other I skip lose points detection and after meshing remove things manually.

What I’m finding is that the latest version of the software has fusion removing large chunks of the part. Like buttons that may not totally connect, Fusion is removing them prior to doing any isolating or overlap detection. I don’t remember it doing this in prior versions. Really annoying when something I have a good scan gets removed.

Yes that is really annoying when it remove them thinking it is a marker , just algorithms. I will forward it to the team and we see if they can improve it .
I just came up against this issue too. There’s an isolated floating element that I do want to include in one scan. The next scan will ‘join it up’ to the main object when I align them. But there’s no way, even at 1% isolation rate, to only have RevoScan not select it. I only want to get rid of the loose points. I hope that modifying a selection done with isolation and overlap in RevoScan can be made possible.
Hi @tomg isolation removing everything that is not attached to the main scan at specific %, use instead overlapped points .
This function is not actually designed to selecting single points , overlapping function is dealing with single points only.
Lose points are lose fragments
Also when fusing and using marker remover it will also remove lose points fragments , so should not be selected if your need the full capture .
It is easier to remove lose points after the scan is fused or meshed , by using the brush tool and select the parts that you want to get rid off but manually .
You can select them multiple and reverse selection to get rid of all noises
Thanks for clarifying - all tips gratefully received 
I’m new to RevoScan but an ‘old hand’ with 3D scanning and photogrammetry.
I’m scanning in feature mode using a Range 1 and fusing at 0.3mm using the advanced fusing method. The isolation tool selects 95% of what I need to remove, but I just need to deselect that 5% and it would still be really useful to just be able to do that with a lasso or similar (or protect it in advance with a mask brush).
In the example where I first noticed it there was an island of points that were isolated, so I understand why they were detected and selected by the tool but this particular island was important as my second scan contained the other side of the feature which connected it to the main body of the object I was scanning. I got around it by using CloudCompare, which is my usual tool, but I do like where RevoScan is heading.
The overlap tool is great for also dealing with noise.
Thanks again for the workflow tips!
I totally understand and agree , however the isolation feature is not a tool , it is based on algorithms and can’t be mixed together in combination with tools from the right side of the screen.
The isolation tool brush you can find on the right side of the screen as well and select more precise what you want to get rid off and much faster than using isolation feature itself .
Just select with the brush what you want to keep after fusing , then reverse the selection and done. Same function but much faster and fully manual .
I do use Cloud Compare in difficult situations as well .

Also using Advance mode for fusing , it will also clean up a lot more than when fusing using the Standard raw mode , so if you need to keep as much as possible of the raw scan , use standard mode and clean manually.
