Another way to get around the "number of facets" error is to split the model into small enough parts and convert them individually
Hi shmuly krayno Thank you for watching!
Yes, that is great adviced! Pinned!!!
Great video as usual. Whenever I use Fusion 360, my inner monologue now has a Scandinavian accent :)
LOL, Paul, Thank you for watching!
Thank you very much! That was awsome! I just can't stop wondering about power of fusion 360.
Good stuff. Found the vid for one thing I wanted to do, and it had 2 or 3 things I needed to learn. :)
That is awesome to hear Jeff Praski .Thank you for watching the videos
Lars - I think Reduce was giving you trouble because you were mistakenly trying to increase the number of faces. What do you think? Great videos, as always.
It may reduce confusion to know that STL files do not have dimensions, only numbers. Some how something has to define what a number means, whether mm or inches or whatever. So the first time you open an STL, it's common to not have the defaults set the way you want, and get something 25.4x larger than you intended, for example.
Can you explain further why we want to disable the timeline? Does it adversely affect anything to leave it be?
If I open the STL file, then I have the option Mesh to BRap, but if I insert the Mesh into the existing project - I don't have such option.
As usual, a great video and awsome tutor. Also nice to see you struggle with stuff😂😂😂
Once again thanks for the awesome videos, I personally have learned many tricks and techniques watching. I use fusion primarily for 3D printing, many times I have had to modify a stl file which is complex having fine resolution, these triangles of which you speak give the model the shape, overall form and reducing the faces causes problems. The trick or technique I am searching for is how to import a stl file with the sole intention of taking that complex 3D surface model and creating solid bodies that I can modify in the sketch environment.
The problem with STL files is the triangles. If you didn't make the model, you're probably not going to have much luck. If you have something like 3d studio max, you can try using the quadrify function, but it doesn't produce the best results.
If you made the model yourself, (or know the person who did,) your best best is to make it as all quads, then export it as an OBJ with the triangulate option disabled.
This will allow you to import the OBJ file in to Fusion, and once in there, you can use the convert quad mesh to t-splines function to give you a model you can work on in the sculpt environment. You can alter it as you see fit, and even convert that from t-splines to a solid body. You won't be able to modify it by simply adding dimensions to change the size, but you can create sketches and use those to modify the model with cuts/extrusions etc., and you can even create sketches using the geometry by projecting edges from the model.
If you want to change the dimensions though, you'll need to use the scale tool. It's not straight forward, as it doesn't give you dimensions as you scale, but by measuring, or checking the bounding box size (if your model is appropriately oriented) you can use those measurements to find the right scale factor. So say you have a mesh that's 12.4cm wide, and you want it to be 11.3, you need to divide your desired size (11.3) by your actual size (12.4). By entering the value of that calculation in to the scale factor box, it will resize correctly.
You can do it uniformly or non uniformly for each axis, you just need to calculate all 3 axis factors for non uniform.
Thank you for the suggested workflow. All of the files that people bring me to 3D print need some modification in order to print the model.
Nice recovery Lars. You do well in live mode.
Thank you Brendan Owen :-)
Thanks for the vids Lars.
I don't know if it's possible, but I was trying to use the match command in sculpt environment the other day, and I couldn't get it to work with what I was working on.
I've seen it work on like, a plane with a hole in the middle, where the middle hole gets matched to the border of a hollow cylinder (like a plane wrapped in to a cylinder) but I wanted to use it to match a "fill" to the hole. The example I saw was using 2 t-spline bodies, so I know it can worth with that, but for me, I was unable to select the second body edges to make the match.
To give a clearer picture, I had a finger, and there was a hole where the finger nail was supposed to be. I copied the faces off one of the other finger nails (to a separate body), and tried to make the border edges of the nail to the shape of the hole so I could merge the edges nicely. I didn't matter if I selected the border edges of the hole, or the border edges of the nail first, I was never able to select the second set of edges to match it to.
If you have any idea how to do something like that, I'd love to see a video on it :)
WOW, I was screwing around with the 'file/open' option, and it came in rough 10X larger than it should (Maybe was using thumb widths as the units instead of mm, inches would have been 25.4X) ... I guess they should delete that option as it is junk. I tried cleaning up my STL file by deleting the surface faces and when I selected one, it said that I need to have them all on the same face, so was that triangle not in the same plane as itself? Nice error message. Thankfully, giving up on that I was able to convert it in spite of the warning and when I converted it to a solid and later converted it back to an STL file, it wasn't manifold, but it was able to fix it in the host program and print it. Not sure why it converted to a solid that wasn't manifold... but thanks to your help, I was able to make it work in Fusion 360 and it is printing now.
THANK YOU LARS!
Love your vids. You do a great job! Sure I have watched you struggle with this same model in the past. Is this a re upload?
Hi lowtus7 Thank you for watching!
Same models I used the last time, and yes! lol, I was also struggling that time
Hi Lars,
Great tutorials. I'm stumped on something I believe is simple but can't find the answer.
When importing my STLs, some have brown faces, some have purple faces. The brown faced stls do not render well as they reflect too much light and are not transparent even with clear glass appearance selected. I did convert to BREP, and still the same issue. What do the different colors mean? The stls that come in with purple faces, work great, they have brown interior faces. Thank you!
great stuff - great video - thank you!
You are so very welcome :-) Thank you for watching!

Great tips as usual!!!
Thank you Kostas Froudarakis
Hi
I enabled the mesh work space in the preferences menu but I do not get the work space. Can you please help?
Are you able to import completed multi part object files (ex. - stl's, obj's, etc.) from another software for animating in fusion 360? If so would you happen to have a video on this or would you be able to create one for an upcoming video? Thx!!
You can import completed parts. Turn them into solids and add the joints. But I would look at something like 3Ds Max if you are looking to make animations
@@cadcamstuff Thank you for the fast reply and I'll definitely look into that. Thanks again!!
I have brought in the mesh, converted to solid, but how do you place it on a plane or pin it to the origin?? I want to mirror the solid body but it is not assigned to a face or origin point. Thanks for any help with this.
You should be able to use the Move command to move it to the origin
i tried this a few weeks ago with an stl file off thingiverse and when i ran it through my slicer ( cura) it came out scaled up about a 100 to one ! why i have no idea ?
i ended up re drawing the design to the dimensions i needed instead.
You did this video 2 years ago (almost to the day) and none of the comments provide a possible solution to the conversion failure. The software is struggling with the conversion because the number of triangles are consuming all of the computer's memory. You had 3 windows open in Fusion 360, each of which has their own mesh info and all of these are consuming memory. If you closed the other 2 windows (tabs), you probably could have done the conversion. You effectively did this when you closed everything and restarted the app and it worked when you just had one tab open.
And I assume that once the thing is made solid, it will be easy to align it with the Origin so that its X-Y plane is at the bottom and the Z-axis end-mill will be pointing straight down so that tool-paths can be done. Getting that alignment with the origin defeated me when I used Data upload. Everything else was fine. But not being able to align it made the result useless. The trick of using Mesh Insert will be tomorrow's task, and I hope all the hair that I 've been tearing out will hit then Undo.... ;-)
Thank you for watching 👍😊 Did you ever see this one? ruclips.net/video/EejRr-Y3174/видео.html
@@cadcamstuff No, I hadn't seen that one. Thanks. I shall add it to my vast Lars collection ;-) I am still getting to grips with 3D technology after having spent decades in 2D, so every bit of help is appreciated. Perhaps a Scandinavian accent is needed... ;-) My Stepcraft is still sitting forlornly, yearning to get going, but the first thing I want to do involves a topographical STL, which till now had defeated me. It would have been nice if Fusion 360 saw what we see--a flat STL surface looks like a plane to human eyes but Fusion doesn't see it as one. It would be even nicer if Fusion asked when it saw a mesh file being uploaded if it wanted it treated as an insert--or if it just did that automatically, and asked if we wanted it converted to BREP, rather having to select all that manually.
The CAD within Fusion is based on mechanical CAD, so mesh and STL Files is not the core of the technology. The development team have added great functions compared to other mechanical CAD out here, but there are definitely more that could be added...These guys are very smart, sure they have more cool stuff up their sleeves in the future
@@cadcamstuff They are indeed smart, and their product is well-named. 360 covers the full circle. Being a newbie, just in the process of setting up, I have looked at other products, including one of the top CAD packages, IronCAD, but Fusion 360 has both excellent CAD and CAM. IronCAD's drag-and-drop facility is very good, and I hope Autodesk will add it to Fusion 360, but on IronCAD CAM is only a third-party SprutCAM, which has very few post-processors.
And I think Autodesk's ploy of offering Fusion 360 free unless you are making more than $US100,000 out of it is brilliant, because at no cost to them it gives them a huge test-base/beta-base/suggestions-base immeasurably larger than they would have if the software could only be bought, and on which they can build a far better product for their paid-for-base. Very clever. There is no substitute for backsides on seats. Take a 360 bow...
And thanks for all your videos. I would be nowhere without them. :-))
so you ended up with odd triangular faces. how do you smooth it
Hi J P Thank you for watching!
You could bring it into the sculpt environment and start working with it there:

Best,
Lars
Thank you for the video
You are so very welcome :-) Thank you for watching!
having issues deleting the faces, I get the alarm
The selected faces could not be deleted.
Ensure that faces are only selected from a single body, and that no duplicate or invalid geometry is included in the selection.
Can you make a video on the "rules" of 3D printing. Like the 45 degree rule
LMAO " when modeling software gets down on it's knees! "
When I import stl file it changes the file to metric! How do I fix? Banging head!🥴
Try to use the insert command in the top toolbar
/Menu
Lars Christensen thank you I’ll try it tonight
kkk was very fun to see you fighting with the Fusion, I think this kind of things never happen with you, rs
hi from new zealand
Hi Andrew! Thank you for watching!
Convert it down to 50000 worked for me
?
MESH! reduce will you!!!
Yes, why do I struggle with this? lol
dude just get to the god damn question
Thats right. U talk 2 much.. sorry
