- Опубликовано: 6 июл 2024
- In this video we are going to expand on User Parameters by going back to the basics. To understand how powerful User Parameters can be we need to understand how to apply them. So we will begin by looking at Sketch Dimensions and Constraints. There are 7 main areas to cover.
1. Dimensions, Constraints and Linked Dimensions
2. Creating a Basic User Parameter
3. Naming Parameters "On the fly"
4. Linking Parameters to Features
5. Advanced Operators and Functions
6. Sketching Construction Geometry and Driven Dimensions
7. Limitations

Something that i found annoying is, i'm trying to make a spool for cable in Fusion 360 and i am unable to do the following: (CableWidth%SpoolWidth)*CableWidth
for some reason when i put the second CableWidth in, it then invalidates the entire thing.
Yeah, the issue with this is that you are taking a remainder(which i think you might want the spoolWidth%CableWidth no?) and multiplying it by a unit so you will need to make sure the parameter unit is lets say sq MM if you are in metric. Fusion is very picky about the units.
The way to get around this is to make your cable width or spool width parameter unitless(i think). But then if you want to use that say in a dimension dialog you would need the UP name like SpoolWidth and then in the same dim dialog you would need to multiply it by 1, which will take on the default units in your document. This way you can still drive your parameters(without needing an area unit) and use it in your sketch.
One thing about creating a parameter and setting the units is that when you enter a value into the dialog like 26 * 3, it doesn't apply the unit until it is solved. when you take a parameter that is defined as 26mm and one that is 3mm and try to multiply them (length x width) in a parameter you will get the error.
Hopefully that makes sense, its late and you should never do math late ;)
@@LearnEverythingAboutDesign I came from Inventor and this was way easier when i could just use an accompanying excel sheet for my designs.
Also, about the suggested correction. Close. I was actually going for:
SpoolWidth - (SpoolWidth % (CableWidth / 2))
Then I was going to pick up the slack elsewhere in the design.
@@george-broughton Yeah using a spreadsheet for stuff like this makes it much easier. and Inventor with its iLogic can be much easier. But to be fair I believe the problem you had here with units is the same in inventor. If you take a parameter times a parameter like SpoolWidth * CableWidth I think it will still fail because it is bringing the unit with it vs entering a number in the equation which won't evaluate until the end of the calculation. This is different than how using an Excel spreadsheet is treated. The only way around it (that I am aware of) is to make the parameters unitless in both Inventor and Fusion when trying to multiply them.
@@LearnEverythingAboutDesign My updated math is accepted, whereas the old math isn't. No changes the units column in the parameters table were made.
I was going to say that this seems like performing mathematical operations between numbers with units and ones without somehow seems to solve this problem, but i just tried removing the /2 out of the updated expression to test that theory and for some reason it's accepting it now.
So, I'm guessing there's just some odd caveats to doing this and best practice is as you've advised. It's just something i honestly haven't encountered in the past 10 years using either software.
I'll probably mess about with this a bit later and see what exactly it seems to matter with.
@@george-broughton hmmm. If you are using (SpoolWidth - (SpoolWidth & (CableWidth/2))) that should work since you aren't multiplying unit * unit. If you original one is now working I am baffled :). I am going to pin this chain to the top as it is interesting and im guessing frustrating to many people. Please let me know if you figure it out if there is some weird order of operations that does work or doesn't. thanks!
Very solid tutorial! I came looking for the differences between user parameters and model parameters and you gave me a clear explanation and many tips to boot. Keep up the good work!
Great to hear!
good job buddy, dont stop. keep cranking out new videos. I am a fusion360 fanatic and most of the channels that I've been following stop uploading videos after a certain amount of time. I really want to achieve mastery in this software but unfortunately for some reason, they stop uploading.
Thanks Zeeshan! What types of things do you want to learn in Fusion? I have made loads of "courses" for Autodesk on various topics and I can point you to ones or of course cover the topic here.
So this video has gotten more views than I expected. Curious to know what was the most useful or what was possibly missing from the video?
I think the best reason for this amount of views is because it's a nearly touched item. Not many "courses" speak about dimensions and parameters, while they are oh-so handy. They go for dimensions and smooth/manipulated surfaces, but not the deeper structure behind it. Thanks for showing and explaining.
This video was very informative and well presented.
Thank you! After this video there was an update adding if statements. ruclips.net/video/91LBG-3DkpY/видео.html
Thank you for making this. Even though I use User Parameters a lot (pretty much every design), I didn’t really understand how easy is was to pick relative parameters by clicking on the dimension or the additional feature parameters that get generated automatically, etc. Learned several things that will help!
Awesome to hear! be sure to check out one of the more recent additions, IF statements. ruclips.net/video/91LBG-3DkpY/видео.html
thanks for the great tutorial. I am trying to make sort of report of my user parametrs along with the design including all the parametrs i have set like wood thickness, total height, etc to send it for manufacturing. is there a way to do that ?
natively in Fusion no there isn't, but there is a free tool in the App store that I think will do what you want.
apps.autodesk.com/FUSION/en/Detail/Index?id=1801418194626000805&appLang=en&os=Win64
I haven't personally used it but that is what i would try. I also have some API videos on making macros that let you bring in parameters from a CSV file and that could be the basis for writing the code to export them like the app does, but start there and see if that works for you.
@@LearnEverythingAboutDesign i really can’t thank you enough i have been looking for something like this all day long. Although some of the parameters are not shown properly for some reason but still really appreciate it. Will be glad to have a look at the script you mentioned too. Cheers
Awesome info. I’ve been looking for a solution to specific problem I guess. I’m making a cabinet with drawers, but want to have the ability to change the number of drawers based off reveal between each and viceversa; and have the actual drawer box also change proportionally. Any advise where to start? And videos to watch. Thanks for your time
The one function missing is the if/else function sadly, but you could make something work pretty closely. There might be some future functionality that will help this but currently the only video I have that is close is this one. ruclips.net/video/-BPcktQwIIY/видео.html I go through a few examples, one being a wooden fence where we update fence slats based on length. Using things like floor and ceil will help with rounding.
I came here looking for the same thing from another video where they showed it in action but did not give the details. This entire video has been incredible. Thanks for sharing the knowledge.
@@MrTmorton77 I have some updated parameter videos as well since Fusion now has IF statements. ruclips.net/video/91LBG-3DkpY/видео.html Be sure to check that out if you are looking to use some of the new logic.
Ohh wow that is awesome! I will check it out for sure. @@LearnEverythingAboutDesign
I really hope they would add the If logic at some point.
Me Too! I did a video on updating patterns with logic and use the round up/down functions but still nested IF statements would go a long way. They do have them in the CAM Expressions you can write inside of toolpath dialogs. Just not here...
Great vid! Thanks. Still think params on the fly should be a user param by default. Just wondering why you dont use a diagonal line at 35:40?
That would be great rather than having them be favorites!
On the diagonal that would be a great option. At 35:32 I do mention/show corner to corner. I generally use midpoint from the edge because I often don't need to do this. If i need a diagonal it will often be a center point rectangle as the start so it is just there. Usually i will do the midpoint of an edge for something like a hole pattern. Some of it is preference. For this specific design the corner/corner would be the quickest and easiest way.
@@LearnEverythingAboutDesign Yeah a lot of diff ways to do it. Im use to other packages where you can hit a shortcut and waits for 2 point inputs (and I use diag a lot) then the centre point of whatever was executed before the shortcut will be placed.
Bit hard to unsilt all the other progs...even inventor as F360 is similar but in some ways not. Cheers and keep un the great work!
@@Art_Of_Sound yeah. I used to love Solidworks sketching and some things are nice but it is really hard to bounce between inventor, solidworks, fusion, and others that i use. Would be great if they would all just pick one way :)
I have student version of fusion 360 ans I'm not able to find the change parameter option under modify.
That is strange, I do not believe there are any limitations to the EDU version design tools. Do you happen to be on one of the remote access student versions? or is this installed locally on your computer?
