3d scanning

[juberafab]

3d scanning seems to be a common practice now of days. It has always been something that I have been interested in and would like to get into. The days of reverse engineering seems to be a thing of the past with modern technology. I will be building two similar truck in the near future and would love to design them completely in CAD. I would prefer to invest the money into a scanner rather than pay someone and not learn. I have other smaller project that I plan to test with first. Is anyone on here currently using a 3d scanner or have any advice i am all ears.

Thanks,
Ryan

my company does... but in way bigger scale than you need. lol But if you want to measure a building... let me know.

This one was recommended to me by a guy I’ve used for solid modeling help. He said it’s a really good bang for the buck. The raptor/raptor pro ones.
They’ve gotten so much cheaper in the last few years.

I have the shining Einstar and it with well. It’s really helpful for designing plate to tubes that are off axis

You’ll need a computer that’s really up to snuff. It takes. A lot of processing even for small files

Thanks for the reply Brandon and Bodj. I have a workshop computer that I tun SW on so I should be good there. So what the process? Scanning, convert, scale, then convert to a solid model? Is there software for the scanners etc. Might be time for youtube university. lol

So when you going to come over and scan the wife and sons cab.

Hopefully the shop computer is up for it. Modeling takes a ton of processing power.

For me it is: scan as many times as needed to get the features I need, then mesh it all together (converts the file from billions of dots in space to triangles that show the topography as an infinitely thin, hollow shell of what you scanned. From there I actually like Fusion360 for modeling. If you convert it to a solid then you get something with a ton of lumps and bumps and no reference data. So you need to create planes on features you want, then sketch a shape of what that feature is. Like if you scan an upright, you’ll need to create a plane on the end of the snout, sketch a circle, and then extrude the circle to make a perfect spindle. It’s pretty time consuming. You’ll do that for all of the features you want/need, and basically reverse engineer the part that way. When I get to my computer I’ll send you some YouTube videos I found really helpful.

Oh, no need to scale anything. That is done while you scan.

Got ya. So i amno computer person but my buddy that built my computer said it was a good one. Has like 5 water coolers in it and 6 or 7 fans with 1 terabytes for storage and another ssd for the operating system. At least that is what I remember. Probably wrong on the terminology. It's strictly my designing computer

I do.have fuzion on a lap top buy it doubt that computer can do it. That makes sense. So are the better scanners more accurate or what sets a more expensive scanner apart.

I’m not sure of the benefits of a better scanner. Probably the mesh software that comes with it and ability to get more data in each scan without losing tracking. I’ll sometimes have to do like 5 scans and then use the software to combine them to one scan. It’s pretty crazy how good it works.

I have the limited low budget version of SW so my mesh stuff is limited. If you have the full thing I’d imagine it would be better. I really like the ability to do a “mesh section sketch” in fusion, where you create a plane and it creates sketch data on the plane anywhere the mesh intersects. So if you have a bolt hole on a tab, create a plane on the tab, use mesh section sketch, and it will give you a rough shape of the bolt hole (real surfaces aren’t 100% flat so the whole circle may not intersect the plane), and then you can draw a circle of your known/defined diameter and place it over the hole more accurately.

I have tomorrow afternoon free if you want to call me I can FaceTime you and show you my setup

We have the Einscan Shining Pro HD at work and I'm sure I'm doing something wrong, but I haven't had much success with it. I occasionally will try to get the hang of it, and then get frustrated and leave it for another 6 months. Last time I tried it the scan looked good, but it was way out of scale, and I had just calibrated it so I'm not sure why. I have to reacquaint myself with the software and try again.

Also a cordless scanner would be a lot nicer.
