| Hi, I wonder what are the most effective workflows to calculate the wall thickness both exterior and interior and draw elevation drawings from Matterport Scan. Some tips on the internet tell you to scan inside and outside and then calculate the wall thickness, is it the only way to do that? For the Elevation drawings, do we need to scan differently from outside (like using long poles) so that Matterport shall have the correct height of the building. Can we calculate it from the regular dollhouse or we need to buy additional data and then process it? Pro 3 shall be used to scan a residential building space. Thanks & Regards, Fakhar |

| How are you planning to get the data for the elevations? MatterPak? E57 File? I’ve struggled with Matterport getting accurate wall thickness even when I scan exterior and interior. My best advice is make sure you scan on both sides of a door threshold. (…but even then, we often just take a quick hand dimension at the door frame.) |

| Im trying to understand the process. I know people converting Scan to CAD file pretty easily so wonder if elevations can also be prepared accurately. I believe it can be generated using point cloud data but trying to avoid that route due to cost constraints. Not sure For wall thickness measurements at all. |

| @rhelling I agree we never were able to get accuracy that was builder grade. For general purpose it was ok, but the architect we worked with wanted hard measurements, which was not that big a deal on average size homes. It became an issue for larger custom homes and or commercial properties. | ||

| @ron0987 so you would do hard measurements manually? | ||

| @fakharimran This was easier done than it sounds, it always dependent on the client, but most commercial work I did was built with steel studs and minimal walls because they were store front and storage space so very few walls. The only time it got time consuming was older custom homes and most architects were not to worried about it but did want us to not it if we saw noticeable or visible difference. In office space we would make a hard measurement when we started and compare to each door and only note it if we found a major difference which would usually be over 1/4" difference. We did this recorded notes and scan points so we could always go back and tag it in the completed scan for the customer. |

| @ron0987 so what are your workflow recommendations? Process pointcloud data to do the task? I checked it further and found the E57 data is the way to go. Any thoughts and recommendations.

I am trying to find an efficient workflow that shall include the Pro3 scan and little manual work complementing it to ensure the correct measurements. |

| If you just need measurements you can use CloudCompare. Despite it being free it has a lot of tool for many scenarios, including bulding elevation profile. The only problem: you can use some tools like measuring but I highly doubt you can take e57 from Matterport and use any tool you want. e57 from Matterport comes with pre-aligned scans but they are unregistered. The most easiest registration tool I know for this task is Recap. It is not hard to learn how to register scans with it but it is a paid app(not expensive though) | ||

| @Wingman Thanks for the headsup, I got E57 file from Matterport and to my surprise it fairly large file of 20GB for a normal 4 bedroom house. Is it normal to get this big a file for such a small structure as even my computer (2 Xeon/196GB/16GB/NVME) is struggling to work on this file when loading in cloudcompare. I also got the Recap trial version but was thinking to give cloudcompare a go first. Is there any good tutorial/videos that you can point working on E57 data as most of the tutorials are using different formats. |

| @fakharimran Sorry for slow response got tied up on projects, yes E57 files can be quite large. I am not sure about your computer setup I run a AMD Ryzen 9 4 core 16 gig ram, 8 Gig video card and have no problems run Cloudcompare, or any of pointclouds. I used Recap for several years it is very intuitive and will pretty much work drag and drop. I always took my scans and dropped them in the program and unless they were way off Recap aligned them and registered them into one model. For file size when I did the comparison of Matterport,Realsee and Faro of my house the Faro scan was about 17 gig of data for 1600 Sqft. Hopefully that helps |

Quote:Originally Posted by fakharimran e57 from matterport not only comes with point cloud data but it also includes all panorama for every scan. Even though 20GB file size may be a bit abnormal for a regular 4 bed house considering there can be a few dozens of 134mp panos in it it may not really that big. As for computer, you really need something with a good GPU. Look at those that have RTX 3060 with 12GB of Vram. I cannot open most point clouds or 3D models on my old Lenovo s30 with just 2GB of Vram. However on a dedicated 3D desktop with RTX 3060 that's not a problem at all.

| @Wingman Thanks a lot. I was having some performance issues with cloudcompare besides my 16G vram and in the end I got e57 file working in Recap (trial version) and it worked like a breeze. The auto register process was quick and also trimming was very fast. I exported the file with 10mm point difference which dramatically reduced the pointcloud file size. Thanks a lot for all helping me out and stay blessed. |
