I have found both the videos that you have produced, re Tolerance and Fit highly informative, but like @mingmac I have the same question, is there a way that these tolerances can be saved be saved into Fusion360 for future use. I have researched t'internet and am unable to get a definitive answer to the question.

Most of what you note in your video can be addressed in the slicer parameters rather than modifying your designs (tolerance fits). You can also adjust for things like material shrinkage which will throw a lot of the fitment done in the design out the window.
@practicalalchemy407Ай бұрын
Heyo! Technically speaking, you are correct, a lot of what I'm explaining in this video “could” be done in the slicer and I've been really impressed but what slicer programs can do and how much they have evolved over the last few years. But, as Dr. Ian Malcom says (kinda lol), “just because you can do something doesn’t mean you should”. In my opinion the slicer method is a solid ‘hack’ if you are using someone else’s CAD / don’t have the ability for to modify the CAD file BUT it has limitations as complexity increases. Let’s say for example you have an assembly that needs to snap together in one area but have a working slide or rotational hinge in another… for something like that I’m going to need to have localized control over fit offsets. I also work across platforms so I can’t always rely on a slicer. When I'm CNCing for example it’s important to understand the underlying principles to get everything to work / program toolpaths properly. Overall I think if the slicer is working for your applications keep using it, but if you want to have more control over what’s happening ‘behind the curtain’ I recommend integrating the offset principles into your modeling process :). Cheers!

I understand offsetting the shaft, however why do you need to offset the adjacent face? If the shaft clears wouldn’t the lid close anyway? It seems like it’s just closing .4mm lower. Someone help me understand.

This is not a good approach. There is the "Press Pull" option that allows you to simply select faces and specify how much you want to them pushed in or out.
@practicalalchemy4072 ай бұрын
Hey Jonnie, Appreciate the feedback. Your comment brings up an interesting point that probably warrants a follow up video from my side. I actually really like the convenience of the “Push / Pull” feature inside Fusion BUT I also think it has some issues, especially for beginners. My main issue is that it tries to do too much and combines too many other features together. Personally I like to be intentional with my features and order of operations so I don’t like how Push Pull contextually switches functions. Yes it keeps the timeline clean but it comes with the risk of losing your design intent/ your ability to track changes if you aren’t careful. The other (minor) issue I have as someone who bounces between CAD programs is that there’s no direct 1:1 in the other programs so that can be confusing for beginners. Regardless, you make a good point that by only explaining the basics principles for adjusting fit in this video I don’t explain the faster techniques for actually getting the job done.

Hey this is a great video! I am now designing a computer chassis in Fusion 360. I have studied this "tolerence" topic before and I found that the "transitional" tolerence of my Bambu Lab X1C printer (with PETG material and 0.4 Nozzle) is 0.3mm. So I created a "Tol" (tolerence) parameter in my Fusion 360. I added/subtrcted this "Tol" to the dimension when I design something like dovetail connection of two boards. So my questions are: 1) Is my way of resovling the tolerence issue like above right? If yes then I am going to do this to every part of the components where I see there is tolerence issue. Correct? 2) I know that there is setting in printer called "Horizontal expansion" (Cura) or "X-Y hole compensation" (Bambu). Should I use them to resolve the tolerence issue instead of doing it in Fusion like #1 above? 3) If I want to share the STEP file with others (not the Fusion file) should I put a note there and tell the user the tolerence setting I have so that the user can adust on their own? Sorry for many questions above. 🙂 Appreciate your time and effort!

Nice Video. I just started to use Fusion 360, before I was using FreeCad which seems much more complex and less pleasant. I think it easier to us "Press Pull" feature on selected walls to adjust clearance/tolerance instead of doing offset on sketch.

Great question! The fun thing about 3D modeling is that there isn’t necessarily a right or wrong way in a lot of cases, it just comes down to what makes sense for you / what is the fastest workflow for you.

While things do change over time, when I drew a rectangle by choosing an upper left and lower right, my rectangle was already constrained. I could not click on an edge and alter its size or shape. Is this due to a change in Fusion, or might I have a setting different from yours? My rectangle edges are all light blue. And after adding a dimension to the horizontal and vertical edges, my colors remain the lighter blue with no highlight due to hovering but only by selecting a line after selecting the dimension tool does it change to the darker blue. v2.0.18460
@practicalalchemy4074 ай бұрын
Hmmm that’s a tricky one, sometimes Fusion will automatically apply constraints you don’t want depending on where you click… try toggling the show/hide constraints in the sketch to see if that helps / shows any constraints you may not have expected

I may not be the best person to answer that question since I don’t sell any files currently, but I had got a commenter a few weeks ago who said that he’s found that the fit offsets tend to match up with the nozzle size 0.2mm nozzle = 0.2 mm transition fit. I haven’t tried this personally but it might be a good starting point for you. When you sell your parts maybe offer users 2 versions with the 2 most common nozzle sizes.

Hi! I followed this tutorial but ended up drawing my own shape in Fusion for my test. It worked wonderfully so thank you! I've tried again using the SVG files after converting them from Procreate but I cannot for the life of me get it to do the project stage. Can you offer any advice?
@practicalalchemy4075 ай бұрын
Heyo! Hard to say for sure but I think the most likely culprit if you are converting an SVG from procreate is that there is a tiny break somewhere in your outline where two end points look like they are connected but don’t actually touch… this could also happen if there is a very short line or small corner that the program didn’t connect when you did the offset …. It can be a bit tricky to track down the culprit but if you go into your sketch in fusion and draw some lines across your artwork (like a large x or cross) and then try to project each of the created sections … the section that won’t project is the section with the bad endpoints. Once you’ve identified it repeat the process with a smaller area until you find the problem . Hope this helps!

Printing a fit block is a good starting point. However, there are few variables that this video/lesson does not address! In addition to different materials (PLA, PETG, ABS ... ) and nozzle sizes, there are a few more factors that come into play! Shrinkage is one of your biggest variable and it is highly dependent on the amount of material deposited. 20% fill will have considerably less shrinking than 100% fill. Along these lines, large and thick parts will shrink more than small parts. Bottom line here is that it takes time and many tries to get a good idea how your parts come out of the printer. I use calipers to measure the difference between design vs printed dimension. You can quickly create a table (or graph) that will show the relationship between %fill, size, print temperature and so forth. With the exception of all the fast moving and zooming, this is a well put together instruction video. Thank you for sharing!
@vbikcl2 ай бұрын
This is a good point. A 0.6mm clearance may result in a good fit in one part and one material in one nozzle size, but a poor fit in another part, or another material, or another nozzle size. Even print orientation may have an impact. I suppose if you wanted to, you could create a variety of fit blocks for different materials, part sizes, in-fills, and nozzle sizes to help you dial in the right fit for what you intend to make.
@maschinelab85986 ай бұрын
Isn't the offset making the gap double in your test block? I mean, when you offset a certain amount 0.5 for instance, aren't you making a 1 clearance. 0.5 on each side?

Hi Hans! Appreciate the comment! You are absolutely correct, you could use a center point rectangle and achieve the same result. There are 2 reasons why I didn’t in this tutorial: 1. I wanted to get the viewer comfortable with the fundamental logic behind the center point rectangle … that you can find the center of any rectangular area by locating the midpoint of the diagonal, which is a super important tool as you continue to build on your geometry. 2. I’ll admit this is a bit of a habit for me…. When I learned 3D modeling the center point rectangle tool didn’t exist yet lol. Thanks again!

It's a good tutorial! Only thing I see that might be a problem is that your slots are perpendicular to your rails. When you mount them at an angle to each other on the back plate, your wrenches won't go in. They need to be cut from a sketch that parallel to the long axis of the, for example, a midplane. Or you have to oversize the slot so the wrench fits in cockeyed. Thanks for the tutorial!
@practicalalchemy4076 ай бұрын
Hey AJ! Appreciate the comment! You are correct, in order for the rack to work the way that I designed it you do have to oversize the slots. In my 1st round prototype I had a much tighter fit but found that it didn’t like it for my use case… I prefer to be able to easily ‘grab and go’ when the rack is hanging on the wall vs having a bit of resistance. But that’s all personal preference! In terms of the cut axis, I wanted the design to be easy to print or CNC without undercuts or draft so perpendicular made the most sense but you are absolutely right! If you want a really bespoke design you could extrude the cuts at an angle. This is actually a great example for ‘design tradeoffs’ (production speed vs. wrench fit accuracy)… I think you’ve given me a good idea for a follow up vid! Thanks! :)
@SomewhatAbnormal6 ай бұрын
The parameters for the transition fit are related to nozzle size. In general if using a .2mm nozzle, you’ll use a .2mm transition parameter. A .4mm nozzle = .4mm transition, and you can see the pattern thus forth.
@SomewhatAbnormal7 ай бұрын
Expansion or contraction in 3D printing is related to your nozzle size (among other things). A good rule of thumb for a .4mm nozzle is to allow for a .4mm expansion of material.
