	Hi Folks Last week I scanned the biggest open space to date and I was very nervous about alignment as I have had issues before. I printed off the april tags from matterport site for assisted alignment before i went onsite, unfortunately it was only when I arrived onsite I noticed that only 27 had printed and not 50. Anyway I started off well and following advice on matterport website, I turned off fast scanning. I scanned the perimeter of the room and when I ran into issues I used the april tags as instructed. These worked well when they were stuck to the wall but not when laid on the floor. Anyway when I eventually got to the centre of the space No matter what I tried I could not get any alignment or it misaligned and put the scan in the wrong place. Then I remembered about Cortex and the conversion of 360 to 3D data. So as you can see in the video. I took a 360 image then I place on the map where it should be located and converted the data to 3D. I had to do this for approximately 15 scans(see image ) and after processing the tour turned out as perfect as it could be the only flaw being some black circles in doll house view where i had done 360 instead of normal scanning Please excuse the language in the video but I was happy to say the least as I had travelled a long distance to scan the property see video of completed tour

	So you use april tag for the perimeter, and after that when you scan from the centre, you take 360 and than convert to 3D. Am I right?
