Lars, sometimes I think you love suffering. Why putting yourself in this kind of situation? ahah! That's all for us, so thank you! Creating the parameters at the end is difficult and can drive you crazy, literally! From my experience it is always better to start planning the parameters before modeling. So a big thank you for this video, clear and enjoyable as usual.
That is awesome to hear Francesca Puglisi .Thank you for watching the videos
Thanks for the great tutorials, it is helping me alot as a beginner in cam. I just finished built a cbeam cnc desktop, and i have used your tutorials to get started with cam. And for absolute beginner, i was able to design and mill some parts in fs360, under your guidance. Please keep it up. Looking forward to tutorials on the linking tab
Hi Lars! Love your videos. I’ve watched 20+/- so far. Love your teaching style and enthusiasm! Super helpful and entertaining as well. Thanks for all your efforts and hard work in putting these together.
You are so very welcome :-) Thank you for watching!
This is gold, I'd be sure to watch every video to this point regarding this Desk. Also Watch Jay Bates 2 only fusion video, it is fast paced but has a slightly approach, at least that time. But between what has been doing,, I've pretty much can use Fusion with a fair amount of it's power.
That is awesome to hear Ralph Chetnik .Thank you for watching the videos
Thank you so much. I learnt tons in the space of 30mins. Wish had of known this before designing my workshop cabinets. Now I do. Cheers 😃👍🏻
Hi Lars,
Thanks so much for all the tutorials, they have really helped de-mystify and give me a ground-up understanding of the parametric and history-based approach to modelling that is present in Fusion. With this one you showed me a feature I kind of wished for at the back of my mind and didn't know was there in the user parameters function.
I really hope that in future streams you will take this project further and show how one might approach converting this rough concept model to something more accurate with accurate cut marks, joints, hinges and so on from which you could generate a component cut list.
I am in the early stages of designing some custom flight cases using standard flight case parts (aluminium extrusion, lightweight composite board, metal corners, butterfly clasps, handles and hinges etc. plus some custom parts I hope to get machined). This video, the approach taken in your Skeletons in the wood Cabinet Video and the make a tube chassis with 3D sketch video have all helped point me in the direction to go to develop and iterate my design ideas on this project so thank you for those. For overall ergonomics, I can and will try and use the simple roughing out approach you showed in the skeletons in the wood cabinet video. However, I have to work within total weight constraints as well as overall dimensional constraints since each case I am designing has to be acceptable as hold luggage on airlines which impose both maximum weights and dimensions. To calculate the weights I need to know the overall length of each type of extrusion, how many clasps, handles, corner braces, and dimensions of composite board that will be needed for any given design iteration. I will be iterating overall bounding box dimensions and design ideas using the approaches you have outlined but I wonder if there is any way in Fusion of defining and calculating the resulting weight of a design and seeing that displayed and updated as you iterate? I would also like to be able to swap out one component for another and see how that affects the total weight, e.g. try a different corner extrusion and matching clasps for all mated edges. Also, as I iterate, I might decide, for example, to try a version without a separate top lid, then decide to see how that is affected by changing the overall dimensions versus a version with a top lid with that same change in overall dimensions. How would you approach something like this to minimise the repetitive work involved? (essentially each side will be a piece of composite board, all straight edges will have aluminium extrusion to create joins, corners will have ball plates over them and lids will have mating extrusions and a clasp somewhere along them. I'm hoping there might be some way in Fusion that I can automate adding these features rather than having to add all of them manually for each iteration?)
Sorry for the long list of questions and I hope they make sense (feel free to get in touch if they don't and I can PM you some illustrations and hopefully clarify). I guess there are probably a whole lot of Livestreams already posted and more to come that might give me answers...
Thanks so much for all your time and dedication.
Hi Quentin Brown Thank you for watching!
Great list of questions!!! There could be a bunch of great livestream topics coming out of this.
A couple that comes to mind:
ruclips.net/video/iH0uWFBBo28/видео.html
Also, you might want to look into the simulation workspace for some idea about strength in your design. This video might be a little too basic, but maybe at least give you an idea:

I hope this is useful!
Have an awesome day!
Best,
Lars
12:25 “I really only play with my unit”. I just about lost it! 😂😂
Ha! :-)
Hello Lars. Your video/s make my "unproductive", every Thursday(or day) I can wait to look at the previous night live stream. I'm from South Africa so I do not watch the live stream. So every morning when I suppose to start working I first look at the video.
I learn a lot from your videos. Thank You keep it up. :-)
LOL That is awesome to hear Philip Swart .Thank you for watching the videos
Thanks again Lars.
Here's where things get complicated with my attempts with using parameters.First I decide on an 'origin' to base all the parameters on -
usually the lowest left point.
Now I add a few parameters.. - syntax may be wrong here but this is just an example.
Using your cabinet example.
door_wid=((cabinet_len * 0.5) - ((door_frame_wid * 2.0)-(door_offset * 2.0))
drawer_wid=((cabinet_len * 0.5) - ((door_frame_wid * 2.0)-(drawer_offset * 2.0))
no_of_drawers=int(((cabinet_hei-drawer_lowest_hei-(drawer_offset * 2.0)) / drawer_hei))
As you mention, I guess at some point we need to 'filter' what changes people might need before getting too deep into parameter hell :-)
Hi Phil B Thank you for watching! Yes, parameters are cool and useful, but can also become pretty complex and cluttered :-)
I’m really a newbie at this stuff, so after watching this I went back to your absolute beginner series where you modeled the conduit box and started over with the idea that you would have a couple size of boxes that would accommodate a couple sizes of electrical conduits, i.e. 1/2 inch & 3/4 inch. The box wasn’t to bad, but the lid was another matter! This might be a good continuation for you to do in your ‘beginner series😋. One thing that made no sense to me was that the ‘origin’ did not stay in the center of the extruded box bottom when the box was reduced in size from fitting a 3/4 in conduit to 1/2 in. This caused me lots of problems when trying to model the top so that it would also ‘shrink’ when a smaller conduit size was used.
Hi Mike Hall Thank you for watching!
Was there a constraint making sure it should stay on the origin? Sounds like one of this small issues that can make you pull your hair out :-)
Thanks for the quick reply. I don’t think there was a restraint causing the issue, but since I made that comment, I discovered what was driving the issue. I noticed that if I added fillets on the outside corners of the center rectangle on the sketch, then did the extrusion, the origin did not stay in the center of the rectangle when the ‘box’ was ‘shrunk’. If I extruded the sketch first then added the fillets followed by shrinking the ‘box’, everything worked just fine. Please let me know if somehow a restraint was generated without me knowing it. If you have an opportunity, try to reproduce what I described above.
That is a useful feature, I'll try to use it. What about the mystery you left at the end Lars? - where the drawers did something weird when you changed the length?
Hi MrNursi Thank you for watching!
Yes, I should look into that. Sure it is an issue between the keyboard and the chair
Haha.Like my old dad said to me, it wasn't the car that crashed, it was the nut behind the wheel!
Lars Christensen
Another great tutorial. BTW: What is that metal cream coloured box with the red button?
Haas CNC G-Code Simulator is what he said before I think...
helicopterdriver
Thank you
Yes, Thank you helicopterdriver.
It is the control from a Haas machine. You can simulate the code you get out of CAM from within Fusion
Full of the usual awesome info. Thanks Lars.
You are so very welcome :-) Thank you for watching!
wow! fantastic! what a powerful feature - thank you!!
You are so very welcome :-) Thank you for watching!
Great tips again, thanks. How about creating a parameter for the door to enlarge as the cabinet size changes ? I mean , a dependency based on proportion or percentage ?
Hi Marcos Tadeu Cosmo Thank you for watching!
Yes! Parameters are your oyster! You can set it up so the door gets bigger or you get another row of draws
Could you recommend a system of parameters which would say once cabinet
length =>1200 number of draws = 3 ?So set some parameters which automatically increases number of dowels or draws etc without manually changing the draw number every time?
Fusion needs a double line and double polyline that you can control the thickness and how it will snap so one does not have to draw rectangles. It would make drawing cabinets or anything else that has a constant thickness easier. So your cabinet is 3/4" Birch plywood, you select double line, enter the thickness of 3/4", then drag and entre a length. Great for cabinet makers, plastic shops (always deal with a constant thickness) etc, etc.
Hi Tom McCaw Thank you for watching!
Interesting, so instead of a corner regtangle, you are looking for two double lines?
Best,
Lars
Well, not instead of, but along with. Can you insert pictures here in replies?
Hey Lars, can I use the value of a Parameter as a Text? I define the Variable "Lenght" and give it 80mm for instance, and I want to write this as a text onto my object automatically.
"Drawers", not "draws" :)
Can you put mathematical expressions in the parameters? That is, could you have something like Height = 200 and another Width = Height / 2 ? If so, what kind of math operations are accommodated? Square Root? Sum, Average, Circumference? etc. ?
Hi Roger Garrett Thank you for watching!
YEs, you can make that kind of expressions...Now for me, I have only used to to show simple stuff when presenting in front of a customer
Lars, Just sent you an email requesting the data set for the project in this live video (a couple of years old, but invaluable the same) , I think I called you 'Chris' on it --my bad--; so, if you can point me to where I can download it, please, I will appreciate it.... stay safe!
would it be better to start over?
In patterns when you use spacing or extant what is the reference. the edge of a sketch or body, the center? Many times when I use the pattern function; the center of a sketch to the center of the next; edge to edge? Maybe you can explain it in more detail. Thanks Lars
Hi Thomas Kittredge Thank you for watching! That was actually a really good question. I had to go and test it out :-). The little icon in the dialog box probaply explain it the best, The dimension comes from the back edge of a line and center of a circle
Best,
Lars
Thank you sir for your quick response.
Nice Job
Thank you rex mcgurk
hi amigo. We are learning a lot with you. I am 56 years old. Mechanic. Can I use this to desig smalls metal platforms with a single stair or ladder? whenever you have an small time please advise me.
Thanks in advance

Hi Francisco D Thank you for watching!
Yes, sounds like Fusion would be a great fit for that.
Hi Lars, do you have any tutorial about this?
Thanks for the video...I do have a question on how do I rotate the the part without cursor down to the icon...I hate this
Hi Mark Gruic Thank you for watching!
I am cheating. I am using a device from 3DConnexion.com You don't need one, but they are really nice if you do use a lot of time with CAD software
Thanks, I thought i was missing something , I use a lot of cad , I use the shift key ...works well. You would think they would have this in the software
If someone designs a model in imperial units and I download that .f360 file, is there a way to convert the model units to metric?
For clarity, I need the parameters to change to metric. Not the settings preference.
My fusion 360 not save file how this solve problem
Hi Anuj Dhiman Thank you for watching!
That sounds a problem above my skills. I would recommend that you contact support here:
forums.autodesk.com/t5/fusion-360-support/bd-p/962
Ch. Atta"ch" not attack.
And Sh . Me"sh" not mess.
Maybe those sounds arent used in Danish.
Otherwise you sound like a NY native.
Your videos are awesome and have taught me a lot already.
Probably really cheeky of me, I know zero Danish.
