- In this video we are kicking off a new series looking at the entire process of scanning to part design using a Revopoint Mini2 3D scanner.
We are going to walk through important decisions such as "do you need to scan?", "how do you prepare for scanning?", and "how do you capture good scan data?".
In Part 1 we are going to define the project of scanning a transmission cover for an RC Truck so we can have a scan based design. We will remove the part, set up our scan, spray the part, and capture multiple scans. We will give you tips like how to scan using features and what to do if your scan loses tracking. How do you know if you got good scan data, and how to identify problems before you get stuck in the processing and modeling phases.
Remember that we are a Revopoint affiliate and we have worked out a deal to provide some discounts when purchasing a MIRACO, INSPIRE, or MINI2. Below you will find affiliate links with the discount codes applied for each of those scanners as well as the codes themselves if you would like to manually enter them. The discount will vary at Revopoint's discretion based on their current promotions.

In Part 2 we will be diving into the processing of our scan data. What do we need to do before we bring a scan into CAD and how do we know we have a "Good" result?
In Part 3 we will dive into Fusion and design a new transmission cover for the RC10 truck using our scan data as a template. It is a good workflow using critical features while exploring unique designs. We will print the part, test fit, and conclude the project. - Навчання та стиль
I rarely make comments on videos (which is weird since I’m also a UA-camr), but I’ve been watching your videos for some time now and I wanted to let you know that you have a great channel. No one is doing it like LEAD and I really hope you keep this up, I’ve learned so much from you.
I’ve even picked up a Mini 2 because of you and although I haven’t been able to accomplish what I want from it, just watching you work through the motions actually provides me confidence that I will get there eventually.
By the way, I commend you on your method of not editing out your failed scans, many people try to get it perfect for the viewer but showing us that you too need to a few tries actually installs more confidence than if you’d get everything perfect and in one go.
I look forward to more of your videos! If I can make a request, I’d definitely like to see a video where you scan something medium sized but complex or oddly shaped. I’m especially having issues when the parts are juuust too large to fit in the 3D scanners’ frame, therefore might require multiple scans then stitching).
In any case, keep it up! Great work!!
Thanks for the comment! Yeah its true when you just see a perfect scan it can be easy to think you are doing something wrong and someone else just knows how to work it. With time it will come!
I will certainly be doing more with the mini2. The next video on the list will be looking at the mini2 vs the Miraco a bit more and that is where those larger objects will come into play.
In Part 2 of this series when we process the mesh I do talk about mesh alignment a bit (even though we got it all in a single scan here), but will certainly put something bigger on the list.
I have a revopoint range and a ton of scans, accurate scaling is an interesting point, can't wait for the rest of the series
Great idea Matt
Thanks!
Great video Matt! I love these functional use videos, bringing it all together!
Thanks Austin!!
I picked up a couple valuable tips. Thanks.
Glad it was helpful!
will follow this! this channel is pure gold. I've used baby powder instead of spray before and it works nicely too, I imagine chalk dust too
Thanks! Yeah ive made the baby powder/isopropyl spray before and found that it wasn't nearly as consistent of a surface finish as the true spray. Works for sure.
Again many thanks -this and your previous detailed instructions are extraordinary helpful for me. I just know one guy on you tube who makes also excellent videos in the same unexcited way as you.I am looking forward to the sequel🙏
Thanks :) Not sure how i feel about "unexcited" but ill take it haha.
uh cool
Great video as always but here’s what I really love about it… I just learned that you are a dirtbike guy… Probably riding a KTM 300 so that makes you most likely an off-road dude. And totally an engineer given that 314 is probably your nod to pi. and most likely making good use of a mechanical engineering degree as a young guy having fun in and out of work. I love it. I was that exact guy 20 years ago.😎
Right on most of those points :) im in my 40s so not sure "young" qualifies. and i have a ktm 250xc and a 450 sxf. raced a little supermoto and ride off road and mx when i can.
I was just talking to the wife about buying a 3D scanner.
I'll be looking forward to the rest of these videos. I've got an Einstar that I pretty much gave up on. Getting decent quality scans, especially of smaller parts, is very difficult. It's almost always faster to measure and draw in CAD instead. Ever design anything with OpenSCAD? Some videos on that would be excellent.
Sorry to hear that! The Einstar is a great scanner, but not really for smaller stuff. I think it has .2mm accuracy vs the mini2 at .02. Great for bigger things like cars, but for smaller detailed parts +- .2mm for a 2.5mm hole can be off by a good bit.
I do have some videos on the ExScan software as i did the series with a Pro HD scanner. Shining tweaks the scan software a bit for each scanner but might help with the general settings in the software

Really really looking forward to the subsequent parts. I figured out the scanning part, but i really feel like there HAS to be a better 3D Scan mesh clean-up to fusion 360 to solid workflow that i must be missing.....
Still editing but they will be coming out soon! The workflow is tough sadly but there are a few ways, which we have covered in other videos. You are either trying to replicate the part you scanned, create a new version based on the scan, or designing a part to fit the scan. Once you have that narrowed down then it comes to forms based design or solid/surfaces.
The big thing still missing from Revoscan to Fusion is an alignment..... One trick is that the first frame of your scan IS your alignment so if it could be at a certain orientation that makes sense you can do that. There is also a workflow where you can sent the points from revoscan to meshlab, work on it there, then back into revoscan. but the alignment is still the trick sadly.
The RC part has a flat plane on bottom and some straight edges which help, and we use mesh section sketches as parallel references for this part. I wish there was a one size fits all. Paid software like Geomagic have nice alignment tools and preprocessing options but even essentials is $$$. hard to justify when you are talking about $500-$1500 scanner prices.
Very helpful... This will save a lot of people time and nerves.
Would it be beneficial to have a softbox / photo booth with more defused light?
Not really. So in Part 2 when we get to process the scan data I actually rescanned with the lights off. I have Hexlights on my garage ceiling and they are great but a little bit less light certainly helps. Basically what happens is the surfaces of the scans just are a little bit "fuzzy". Revoscan can still average it out but if you are trying to get as accurate as possible you just want to be mindful of how much ambient light you have in your area.
Great but I need the part 2 please
Same bro! Need to see how you work on fusion to make it a solid!
In Part 2 we process the scan and part 3 we design. We are using the scan data as a starting point and don't make the scan solid fyi. We use mesh section sketches to get references for edges and use that as a starting point.
Great , hope to see the next parts soon 👍💕
@@LearnEverythingAboutDesign then I’ll wait for part 😁 but yeah I’ll definitely watch part 2 😜
If possible for the next part can you compare Fusion with Plasticity?
Well the series is already filmed and mostly edited so sadly no. Plasticity doesn't have a way to use a mesh file yet so it really doesn't fit this application yet. You can import a mesh but its just a reference. In the future when we have tools to snap to a mesh 100% I will make a video on it :)
Thank you for the great video Iwill follow this series 🙂 do you know what is the minimum processor ,graphic card and ram on the laptop/pc you need for prossesing the scan so you dont need to wait a couple of hours😅
Yeah I will say that capturing to my laptop, even an old one, is fine, but as soon as you start processing you really do want a bit more power. Revopoint says at minimum 16GB ram, a dedicated Gcard and at least an i7 chipset. You "could" still work with 7gb and a i5 processor but i find that a better gcard, 32gb+ and a processor that can boost around 5ghz really helps. My laptop is an older i7 with 64gb ram and a quadro p4000 card, but the system is tired and i prefer to work on a newer desktop. My current desktop is running an i7-10700k cpu which is 3.8ghz but has the "boost" which helps during processing. Running 32gb ram and an Nvidia RTX A4000. I haven't had much trouble processing with that system.
the zeiss software is not accesible anymore sadly. How can I align my scans to the XYZ axes?
Wow that is a bummer! Technically you can "align" in MeshMixer. This was an autodesk supported program but they dropped it in 2021. You can still download it and use it but there are no patches/updates since then. meshmixer.com/
Shining3D mesh software exscan has xyz alignmen as do tools like Geomagic. What i have done in fusion is generate planes off the mesh and measure how far it is off and rotate/move. You can do this with mesh section sketches to get the center of a revolved section as well. Not a great solution but workable.

What about scanning for those of us who don't have or want to spend $1000 on a scanner and accessories?
what types of things do you want to scan? There are a lot of scanners on the market. If you are looking to get rough approximations of objects you can do it with a lot of tools, but generally the money spent buys you speed and accuracy. Something like Lidar on your phone might be good for +- .5 to 1mm on an object the size of a mug. Scanners in the few hundred dollar range (INSPIRE and POP series are are in the $400-$500 range). will generally get you around .05mm. The mini2 gets you around .02mm accuracy.
You can take a bunch of pictures and upload them to a photogrammetry site/app but aside from a rough approximation you won't be designing any parts off it.
@@LearnEverythingAboutDesign I'm personally interested in more the "negative" scan side of what you're working on. i.e. scan a portion of an engine bay to design a part that fits a specific cavity or space. I was mostly curious about no-to-low cost options to get started with before fully committing to a dedicated scan tool.
@@Pags222 Yeah that is tough. If you want to try a free option first then you can try photogrammetry or lidar on a phone. You aren't going to get accurate motor mount locations but that might get you close enough to say see if a motor fits or to design something like intercooler piping and placement.
One big snag you will run into is what colors scan best. When scanning something that is either absorbing light or reflecting light you pretty much get trash back. Some lower end scanners can do ok with colors like the CR scan ferret, but offer much lower detail and you are still are looking to spend several hundred dollars.
So yeah id look at free photogrammetry tools first and see what might work for you before buying a scanner.
