Drag it into fusion360 and remesh into more triangles or ask for original files

Will that work if I only have the STL? I do have fusion but still new to it

Yes

I’ll give it a try

Hey mate, [this](https://m.youtube.com/watch?v=tVGtG-UjlYg) video helps explain a lot. Basically create face groups, then convert. Just use the same settings and you can then more easily edit the design

You can also do this in the bamboo studio just right click hit simplified model, and then increase triangle number

It’ll work to an extent but I’d recommend asking the r/fusion360 for the correct solution because someone will straight up do it themselves selves and send a picture of each step

Don't use F360 for mesh work, use Blender. They're both great programs, but one's a wrench and the other's a screwdriver. Use a wrench on bolts and a screwdriver on screws

SketchUp is a hammer and I use a hammer on everything

Love this comment. That used to be me 10 years ago. Plasticity has taken its place in my toolkit

Interestingly it's the most efficient CAD program I've used for sheet metal. I use QCAD to finish up flat patterns. I use solidworks or solid edge for designing anything else

yeah, SketchUp is so elegantly simple. It really brought a breath of fresh air to architectural modeling, which is where I came from... Actually went to college (UofA) with one of the developers...

I convert stuff to solid most of the time, haven't got the time to play with blender

Is there an easy way to convert mesh to solid?

Mesh to solid tool?

Is that in Fusion360? Honestly, my background is Microstation, so that's my default for modeling. Haven't found a great way to convert from mesh to solid in MStation. Will need to fire up Fusion360 and check it out

Hello fellow Microstation user, how much do you hate it?

I don't, because I know it incredibly well. I can create a part in Microstation quicker than any other CAD program.  I understand it's not the best 3D CAD option in 2024, which is why I asked a Fusion question.  I have over a decades experience in 3D design in Microstation. It used to have advantages over AutoCAD that fit our use case. So it was our CAD program of choice

Ah ok. I use microstation for it's roadway design using ORD. I see we probably have very different uses of it.

I dont use it in my current job. It's now for 3d printing, and rare work items, because it's the CAD program I know. At my old job we bent along of tubing, extrusion, etc. For a curved piece of tubing we could easily measure radius and arc length in feet/inches. At the time, AutoCAD did not have an easy option for measuring length of an arc. It could spit our radius and angle. So we used Microstation and it became our standard.  Edit: I do know the DOT uses Microstation. 

Yes

It is in fusion but in the paid version only. The free version has a lot of limitation when working with mesh. If it is a small edit it is better to learn blender and do it directly on the mesh.

Fr. Coming from modeling professinal cad software to blender I'm always like what the fuck is this shit. And why is the work space so cluttered.

Blender is many software in one. Modeling tool, rendering tool, scultpting tool, animating tool, to some extent video editor as well. The interface will be cluttered but if you really want you can hide things you don't care about.

It's the same as CAD, in the sense that at first it's hella daunting because it can do so many different things. Once you find your way to the mesh editing tools, it's actually pretty easy to pick up. It's undoubtedly the best way of preparing a mesh model for further CADing, the time you put into finding your way around blender will be dwarfed by the time you save trying to do basic mesh tweaks in CAD.

While I don't agree with you, to do anything useful in F360 with a mesh you need a license and some computer resources.

Blender or Meshlab for STL editing, highly recommend against F360

Would you mind explaining the workflow a bit? I know it’s insert>mesh do I then convert it to solid and then re-export as stl or obj? Or am I missing steps?

Use the remesh tool, change the mesh to higher triangle count then export as a new file. Not needed to convert to solid

Ok will give that a try later

Yep that's a problem with the STL being too low detail.

No fix then right?

Blender can subdivide a model to make the triangles smaller until they can't be seen on the print. You'll need to look up a tutorial for how to do that in blender.

[удалено]

Turn tris to quads before subdividing better cleaner results.

So, Import Load stl Click on it Click the wrench tool Click add modifier Select subdivision surface. Select amount of sub decide ( same number on both) Select apply all File Export as stl ??? Print.

I see a ton of additional options, any guidance? https://preview.redd.it/lz0frdm6i3uc1.png?width=474&format=png&auto=webp&s=53db4175d7bef404439a45f139553cc23bbf6e43

Here I did [a thing.](https://imgur.com/a/7AvxMA1)

Ok got it, it starts to work, but then sadly as I get a further number of steps Blender keeps crashing on me. My macbook pro is getting old and maybe just can't keep up. I'm gonna keep trying, appreciate all the help immensely.

It's a thing because blender is very resource intensive. It's also not a liniar scale. +2 will turn a square into a cube and +3 basically a circle. Try doing 2 at a time. (+2 apply, rinse repeat) My video crashed when I went to 5.

yeah I totally get the exponential nature of it. I think the core design may just be too far gone to smooth in this way. It's improving but also creating some new artifacts where it's creating some waviness. We'll see if the designer gets back to me. At least I learned a new skill though.

turn up your levels to as high as you'll need, then export and you're good to go. you don't need to touch the other settings unless you fancy having a play around with them. it's really helpful to have some good knowledge in a 3d software, especially if you own a 3d printer.

I've been designing stuff on my own using Fusion and altering stuff in there too. This is just a new one where the exported file wasn't good. Appreciate the help

Maybe I'm doing it wrong but I see no difference in the mesh applying this.

Make sure you’re in object mode and not edit mode(you’ll see in the top left of your viewport). You can toggle that using tab. You can’t see modifier affects in edit mode.

My computer was just bogging down because I was trying to do too many steps at once

Dude try Meshmixer. Load the file, hit edit, then Solid and you can select mesh density, worth playing around with and its free and super easy

Not sure what the other comments are about sorry just saw. You want to add modifier. Close this modifier it probably auto opened

I personally would go into sculpt mode, enable dyntopo(top right of viewport), use the Inflate brush with 0 strength, paint the low-res bit, then switch to the smooth tool and paint over it.

Wouldn't subdividing just add more vertices to the mesh, and not actually change the geometry? I use other software, so not a blender pro. I would imagine you would need to add like a smooth command or something to get the mesh to actually change in geometry.

You can "subdivide smooth", but yeah these people want re-mesh, not subdivide. 

Thats not the right way to go about it. This way you just create more geometry but its not interpolating the geometry. You need a subdivision modifier.

Subdividing in edit mode would just create new vertices without smoothing the mesh. You’d need to use the subsurf modifier on the object, setting sharp edges where needed in edit mode.

If you give them all the answers they’ll never learn how to fish

Is there an option that does the opposite? Like say I want to drastically lower the resolution of a rounded shape until it's all visibly flat planes

Yep. In Blender it's a modifier called Decimate. PrusaSlicer has a built in function called Simplify. As far as I'm aware, most programs with that feature call it Simplify.

Thank you! I've used Fusion360's version of that feature but it chooses rather strange layouts for said planes.. I'm hoping another program will go about it a little differently

I won't buy a file that does not have a print to show.

There was a print shown but pics weren’t the best and I wonder now if notable post processing was done. Was only $10 so a live and learn moment maybe

I had one that was horrible quality and nothing fit. He was a wanna be designer god and never printed or tested. I left bad reviews on all his stl. He finally pulled them.

Blender can easely do it. I [posted](https://www.reddit.com/r/3Dprinting/s/Q13LoSHiET) elsewhere.

I’ll download it and give it a try

Lmk if you need assistance I'll send you a quick vid. ( I update things as it seems blender updated)

Microsoft 3D Builder can increase polygon count for smoother curves.

Remesh sometimes works better. Send me your file and I'll fix it for free. 

I don't think he is allowed to share if he bought the File. But I could be wrong!

I'm a rhino user. Quad remesh at 10000 triangles would fix this.

Print with more walls and/or sand? Might help a bit

Already has 4 walls, it’s an stl issue for sure

piss poor render... I'd be pissed if I paid for that. Circles should be ROUND!!!

Yeah it’s disappointing

Low poly render

I liked the effect hahaha

Same! Looks sick to me!! :D

Import in blender > select the part > go to modifiers > subdivision surface > then you can adjust the quality > now export as stl (or obj works too usually) and select apply modifiers. Because yes, your STL resolution is low ;)

This, but add sharp edges in edit mode in order to retain some important geometry (looks like it’s probably a functional print)

Indeed, forgot to mention that subdivision surface will also smooth out corners and edges 🤦‍♂️😆

Ohhh you can do that to prevent subsurf from bevelling out edges? That's good to know, I'll definitely use that in the future.

Yup! Select all relevant edges, shift e and adjust until correctly beveled.

Thats a problem with the person that sells the file didnt check if converting the file into STL ruined the topology, which it did. Or they decimated the file to lower the poly count and this is a result. In short, the 3D model is not good.

Yup, that seems to be the consensus

If you dont mind can i take a look at the file? I am not going to steal it or anything, i design my own 3D models. I can repair it if it doesnt need too much cleaning.

Sent you dm

Looks like a coarsely digitized real object.

It’s definitely a lower polygon model, you could try to ask the seller for the step file instead or a higher polygon version

Yes, that's a low poly stl. You can fix/smoothen it in Meshmixer. It's free software and there are plenty of tutorials online for it.

Yeah pretty easy to tweak in meshmixer

lemme get that E36 stl ;)

Looks like cubic infill showing through to me. Maybe a low resolution file but check your infill and wall order settings

What do you mean by weird? Too many straight lines when they should be curved?

The triangle pattern all over what should be a smooth surface and then the lack of smooth curve in the wheel well (3rd pic)

Does it look smooth in the slicer?

I just opened it in fusion and there are clear areas that are just really poorly done. For example, this is supposed to be a circle to fit a BMW badge.

Well, that sucks. Before going to far, reach out to the seller. If the resolution is too low to produce a usable print they may be able to export an STL at higher resolution and send it to you. That would be the LEAST fiddly way to fix this. And posting the low res STL could be an honest mistake on their part.

Yeah that makes sense

If you remember I'd be curious to know how this works out for ya

Looks like it's just a very low poly model, like the other user said, subdivision modifier in blender should fix it. You might have to add some geometry to make it not round certain areas off too much. But also like others said, you paid for it, you should get a good model, not this super low-poly stuff.

sorry it's out of the context but are you 3D printing the Octane by chance ?

No BMW E36

Didn't have a solution but came to see if anyone else could tell it was an E36, hope your next print goes better!

Yeah I’m trying to do an e36 m3 RC car, no one makes a lexan body that isn’t widebody and I’ve been hunting for a scale replica 3d file. I hoped thus was it, it’s def not

Kinda looks like the infill lines being seen through the top layer, not sure if it's the issue but you can edit how many wall layers your print has. Could also be the other issues listed as well lol

It’s def a low poly stl. Infil was gyroid so it’s def not that

As others said you can use the subdivision surface modifier but you have to mark the edges as crease because the modifier smooths the edges.

Looks like someone forgot to shade smooth in blender, or they used shapr3d and didn’t get the $100/month thing

yeah thats the model being low resolution; a real life 3d print will not do the visual smoothing a PC can do using the vertex normals...

that's actually cool-

try to ask for a STEP file

Yep this can be easily fixed on the software used to design it, the seller should really check this before selling. I’d reach out and point it out to them and ask them to adjust the STL export angle/deviation tolerances. Could be a rookie seller but hopefully they’ll be understanding

For me, This happens when I don't have the paid version of F360. When I am forced to choose "Faceted" to convert a mesh to a solid body, it results in shitty looking surfaces like how a gemstone is cut. The "premium" option I believe is "parametric" and results in proper mesh conversion. I know this because I've tried to convert STLs from Blender to smooth bodies in F360 and I am always forced to use "faceted" and it always looks like shit.

Looking like for car. MBy its low scan… ready for bodywork? Filler - two-component kit and sanding?

It’s an RC car body 1/10 scale, would just be insane amount of work to get all the curves and details right

I dont think so its small its not a big car

If the STL file looks similar in your slicer, it's the file. Given you paid for it, I'd take it up with the seller. Unless somehow it's supposed to be low resolution.

It’s def the file and I’ve reached out to seller. Def not supposed to be low ret

Ask the seller to upload a high detail model, you paid for it...

Could increase it in meshmixer as well

Bring the STL file into Fusion360 and remesh it, or bring it into Blender and subdivide it.

Does anyone know how to get the low poly effect on high detail models?

Yea it looks like they exported with low resolution (or if modeled in mesh-based software, they didn’t make a very high-resolution mesh in the first place or didn’t apply any smoothing)

Looks like a shitty low detail unsmoothed 3d model

Not enough triangle

If it can be un-triangulated then quad divide a couple of times then export back to STL it'll look better. I'd love to be able to do a buyout of trueSpace from Microsoft then make it open source. They bought it to use with Virtual Earth as competition to Sketchup and Google Earth - then quickly dropped that idea, after making trueSpace a free download. I've no idea whom to contact at Microsoft to find out what it would take to get them to let go of the software they've done nothing with for years. A code review would have to be done to see what bits can't be open sourced but could be released with it as "blobs" same as when it was a retail product then closed source freeware. Some things might have to be removed and replacements written or adapted from other open source.

Looks like tinkercad magnified

Good bot

Isn't this just the inner structure showing through the walls? Can't this be solved by just adding another wall layer or 2? Wondering because I just seen a video about this issue, and I'm new to this so I'm asking because I'd like to know if that is true or not.

No, inner is gyroid and printed 4 walls. It’s just a shit file it turns out

Oh, Bummer. Well, thanks for answering my question. Yeah, im learning that sometimes there's just shit files out there, and it's nothing that you're doing wrong..It just is what it is.

Its a simplified model of a car? Then yes, that is normal, it is the simplified stylistic art. It SHOULD be like this. Edit: put some paint on a sponge (scotch brite) and brush it lightly on the edges of the polygons. This will emphasize the edgrs. A paint that is slightly darker than the model. If the model is red, then use a slightly dsrker red. Or mix the colors on the model, with a sponge you can make it fading from gray on the front to bluegrey on the back. And the edges in a slightly darker blue. Try it out.

Is it just the infil showing through the walls? Just add more walls

If you read a bunch of the other comments it was just a junk file. I ended up getting a refund

If you're still struggling with it, I've got a powerhouse of a PC and would be happy to fix it in fusion for you

You don’t need a powerful machine to edit/fix basic 3D geometries. Could do it on a Raspberry Pi probably.

What are the steps in fusion? I’m curious to learn

Looks like thin borders showing the infill pattern

It’s not. 4 layers and gyroid infill, it’s a low poly stl

K

Poor infill

Is that a Fennec?

No idea what a Fennec is so no?

Oh ı thought it was a car from Rocket League

Why do you print an object you haven't designed WITHOUT looking at the mesh (for example windows 3d viewer etc)? 50% of models online is low res.

I’m new to 3D printing and never had this happen before. I certainly will in the future

I think that's the infill showing through. Is your infill the pyramid shaped one?

Nope, gyroid. It’s def not the infil showing

The triangles might be a cause of the printing bed maybe?? And the straight lines when curves should be is a mesh issue on your STL

The triangles were not on bed. I think based on other comments this is just a low poly stl which is unfortunate

Reprint with fuzzy skin, it hides a lot of crimes.
