Settings are High Accuracy mode, both remove markers and Remove noise are turned completely off. have also tried fast fusion and does the same thing. And yet, when i fuse, detail is constantly being deleted on the last two cylinders. Actually I noticed no difference when fusing with and without Denoise option checked. The last two ports on this engine scan are always deleted and i have no idea why Anyone else experienced this ? is there any workaround i really need this data lol ![image](https://canada1.discourse-cdn.com/flex029/uploads/revopoint3d/original/3X/a/f/af4b31cfa402bf37935bd415e420e239562c2835.jpeg) ![image](https://canada1.discourse-cdn.com/flex029/uploads/revopoint3d/original/3X/2/2/220a0afe20eb4e7c3d80f05391951e3bfcc884b1.jpeg) ![image](https://canada1.discourse-cdn.com/flex029/uploads/revopoint3d/original/3X/6/1/61d9ce022d2b417eca4b242ce2cdba6060567c93.jpeg) ![image](https://canada1.discourse-cdn.com/flex029/uploads/revopoint3d/original/3X/d/f/dfb3cebe91d7ca6380e72f37fb0e1848112ee22b.jpeg) Fast fusion shown below, also nuking these areas. ![image](https://canada1.discourse-cdn.com/flex029/uploads/revopoint3d/original/3X/8/8/8849a9849728eefb559ade904b36969b6e329527.jpeg) ---

Hi @bxp The fusion will delete every area if the scan that are not connected to the base scan , that probably what is going on here. I propose you add the area to the already scanned scan and capture the missing points to avoid the software to remove it. Also how lower the fusion settings how more lose points are deleted , scan of this caliber are usually scanned in section to capture the all angles correctly making sure the whole area is connected to the main scan. Before there was a raw standard fusing function to fuse the scan but it created so much notices that it was removed. I can’t see exactly the parts but you can zip the project and send it to the technician for evaluation [customer@revopoint3d.com](mailto:customer@revopoint3d.com) ---

The car has already been scanned and this is no longer possible. this option has to change because for very tight areas its not possible to see everything. so now im kind of How can i just do a raw fusing or somehow recover that data ---

you could make a copy of that file, then cut away everything but that area and a bit of the surrounding. Fuse, then merge. Ghetto I know, but worth a shot ---

Sadly the case was about people being complaining about too many noises and they had no time cleaning it. That are always the lazy users that suggesting stuff that break other thing up in the process ---

Ghetto I know, but worth a shot Yes that is a very good suggestion Just copy the project multiple times and change the project name , then load it up , cut half of the scan and fuse , it should help preserving the areas , later everything can be merged back to the original scan . ---

that sounds like a complete waste of my time. Can you recommend which version of revometro to download which has the “raw” feature? ---

> [@Nickluvin](#): > > you could make a copy of that file, then cut away everything but that area and a bit of the surrounding. Fuse, then merge. Ghetto I know, but worth a shot Can you even do that with a laser scan? The trimming part, I mean. > [@bxp](#): > > that sounds like a complete waste of my time. Can you recommend which version of revometro to download which has the “raw” feature? For autoturntable stuff, I had to go all the way back to 5.6.2 (and that’s RevoScan5 for MetroX, not Revo Metro) to get a demonstrably different point cloud after fusion that restores a lot of the smaller details (especially in undercuts) that are scrubbed away in current versions. For laser scans, I couldn’t see any meaningful differences. The only thing that made a difference is to never go smaller than 0.15 point distance in HQ fusion (fast fusion seems to lose data no matter what). Oddly enough, 0.15 is the original minimum setting for the MetroX in laser scanning mode, which is either coincidence or conspiracy. ---

Well I’m shocked. Revo Metro 5.8.8: " 6. Adds an option to remove isolated items during point cloud fusion." Seems to work as advertised. ---

Stay shocked then. Its not an option because there its not optional, its forced on every fuse. ---

Sorry, I wasn’t very clear. New version 5.8.8 is available to download. ![Screenshot 2026-09-17 040919](https://canada1.discourse-cdn.com/flex029/uploads/revopoint3d/original/3X/c/0/c0a7bf029ee3734db18e8c43674877b7153e2c8c.png) Quick testing shows turning the “Remove Isolated Points” option off retains the scan data that was previously removed. At least on laser scans. The option exists for structured light scans but doesn’t seem to do much of anything differently. Again these are quick tests. ---

I didn’t get the update until last night. You are right. And for me, this option added did also retain those missing parts so im happy.
