Hi all! Alex from Occipital here - I’m the product manager for Canvas. I wanted to weigh in with a few notes as well as offer to help any time with these or any other issues: simply DM me on the forums and I’ll get back to you ASAP.
First things first: thanks for using Canvas!
Justin is correct that Canvas currently doesn’t have color rendering due to the limitations we have on RAM from the iPad. Room Capture does offer this, but Room Capture also typically only lets you scan a much smaller space (it’s a demo app, after all, and not intended for this use), so the memory limitations are less pronounced. We do colorize the scans after they are uploaded for cloud reprocessing, but that also does cost us some money, so we can’t provide it 100% for free. Definitely something we’d like to make work all on the iPad at some point, but we’ve got a lengthy to do list, so it doesn’t happen overnight
In the meantime, @Justin, if you do just need the colorized scans (which are also enhanced after the reconstruction), we do have a private beta we open up for customers that need it where you can access just the reprocessing pipeline without full Scan To CAD. Just drop me a DM if you’d like to use it and I’ll set you up. Because the scans are reprocessed with more powerful algorithms in the cloud, that also means the measurements should be more accurate, and they also come back to the device for you to use on your iPad, or use in a desktop program with a mouse like MeshLab (a mouse often makes it easier to get precise points).
Otherwise, about the in-app measurement tools themselves — this is definitely something we want to provide better tools for! Measuring the mesh itself inherently requires a certain amount of care and precision, and while the planar measurement tool does help, there are lots of other ideas we have for common measurements you might need to make like door widths, windows, etc. @MontanaKarl, I’m going to reach out to you to get your information and get in touch right away. We do monitor our support email closely, so I’m not sure what would have happened to lead to you not getting a response, but that is definitely not a good experience, and I’ll make sure we rectify it.
I also have a hunch that there might be something to do with scanning technique that is leading to worse scans (the measurement you mention is out of the expected tolerance), and we can probably help. We’ve been working on a tutorial video to help people more quickly learn “ideal” scanning technique, and should be releasing that shortly!
