Heres a good example the first pics is the whole design the second is a part of it saved on its own then added as you can see the size changes
Without a video or model there isn't much I can do here.
At least now I think I know what was going on, at least partially.
If you could export the model I could try your problem workflow, which seems to be "insert mesh, save file, open file = mesh wrong size" is that correct?
I could tell better by looking at the model.
Thanks,
Yes but I do not do any business on FB.
For what it's worth - I was racking my brain over this very same issue. I would set the units to mm in the file *before* I imported the mesh (this file was started from something I uploaded to the workspace), I would even pick the correct size in the mesh but no matter what I would do it would still come in too large.
I then created a new design - set the units to mm and then like before I picked insert mesh, picked the file - set the units to mm and all was well.
It seems like if you are starting a file from an existing file there is some embedded scale that can't be changed no matter what you pick in the part browser.

The browser units do two things. Display and input units, and export units for mesh. The browser units do not affect import of mesh.
Mesh is does not carry specific units, it just gives a relative size to what it calls 1 unit, depending on the measurement scale of the application used to create it.
So, if the application that created the mesh was counting "1 unit = 1 mm", then when you insert into Fusion you picked millimeter units, you get consistent results.
If the application that created the mesh was counting "1 unit = 1 mm", then when you insert into Fusion you picked inch units, you get a model that is 25.4X too big. (1 in = 25.4 mm)
When you upload to the data panel, there is no way to pick the units. The cloud translation assumes "1 unit = 1 cm". This will likely force you to scale the mesh body to get the size right. This is why we suggest that you insert mesh into your files using Insert from the toolbar instead, so you can control the units as you import it.
Please let me know if you have any more questions.
Regards,
Yep that makes sense as to the problem. But why use CM as the default size when nearly every software including your own 123D uses mm as default.
Actually the core unit in Inventor and Fusion, and I'm guessing 123d is actually CM. This is the unit the modeling engine uses. My guess is the translation team picked CM for this reason. The way to solve it is to have a unit picker for inserting files, which Fusion has. We need to improve the upload/translation dialog to include units, but just haven't gotten to it yet.
Translation units and default units are different concepts. Default units can be changed to inch, meter, foot, etc, at any time.
How are you exporting and importing? If you use File > Export > STL, and then Insert > Mesh, what is the result? (do it all from within the Fusion modeling window and command set)
Thanks,
Okay thanks for the clarification.
I think this should be a new thread in the CAM or support forum. It doesn't sound like you are encountering the same problem that this thread addresses, especially because you are using the CAM space.
It's also still unclear what the actual problem is from your description. Can you use Autodesk Screencast to show us the problem in a video? It's the quickest way to understand what is going on and help your workflow.
Thanks,
FOUR YEARS LATER and this is still not fixed.
I tried uploading this file from Thingiverse (https://www.thingiverse.com/thing:2781529) and it always comes in 10 times the correct size. I tried the various suggestions to import a mesh and whatnot and I have not figured out any way to get it to the correct size.
I'm a Fusion 360 newbie so I don't have a lot of experience with doing anything complicated. I wish there was some sort of manual / consistency with this. It's a neat package, but sort of frustrating to use when I'm constantly getting side-tracked by problems in the software.
@Anonymous How big is it supposed to be, when I open it it's about 27x63mm.
If all you are going to work with are meshes not sure Fusion's the correct program by the way.

It's inserted at the correct size for me. The pins are 2.54mm apart.

Sorry to hear it's still a confusing experience. We actually did fix this. The fix for this situation is to allow you to pick units as you insert your mesh files.
Here's the help page for it:

Help topics can be searched using the ?Help menu, upper right corner.
I think you must be uploading the files. When you upload for cloud translation via the data panel, you don't get to pick units. The preferred workflow is the Insert > Mesh workflow. Please let me know if you have questions about it.
Thanks,
Hello,
Thanks for the reply. I have attempted this using all of the various suggestions I've seen in this thread to no avail. Just to be certain, I tried it again just now following your exact instructions and this is what I get (see below). I'm not sure what I'm doing that's wrong. It just doesn't work for me.
Thanks
John Whitten
Your Previous Instructions:
(I'm not quibbling over the minor discrepancy from measuring with a slight angle...)
Then I tried to actually USE the part in another drawing:
(This is what it looked like in comparison to the other elements already in the drawing)
And here is a closeup showing the 10X size problem:
I did try uploading the files. That didn't work. Then I tried it via the "Insert Mesh" method that several people suggested. That also gave me problems (see my previous reply about that).
I do appreciate the help and concern though. I just wish there was a book I could read or a good reference manual that had all of this written down so that I could get a better sense of how it all works from one end to the other. I've been in the computer business for a long time, well over 35 years. I understand and get that bugs happen, "mis-features" creep in, and not everything always goes as advertised. That's all part of the process, both of using the program and of developing new features, etc. Stuff happens.
I just wish that I could use it with less clumsiness to get more of what I want done. It just isn't very intuitive to me-- and I don't say that to knock the program at all. I want very much to be able to use it better. I think it's a very good program actually.
I would really (sincerely) love to come work for you all and share with you my "ignorance" to help you improve your process / interface / whatever to help the idiots like me who really want and need to use your program but just don't "grok" it naturally. I can think of at least two alternative ways (interfaces), along with some other ways to inject on-the-spot help / assistance that would supercharge your front-end and make it easier for newbies / novices and non-CAD experts to use it.
If that's interesting to you, please reach out to me separately and let's talk.
John
