Adjust the diametre of objects in a selection set

[Anonymous]

Hello,

Firstly, I do apologise if this has a technical name that I am not aware of as I have had no real technical training.

I have created a part containing a heat-set (sink) insert which is mounted into what I would call the nut of the screw, which I have labeled, Lid Mount & Screws. The Lid Mount & Screw are a seperate fusion file and I bring it into the SCB case file and leave the links "unbroken", as I do not want to scale these three parts.

Now the "nuts/bracket" of the Lid Mount & Screws are connected to each of the cylinders (yellow) to enable the lid (black) to be closed tightly.  However, I have found that the cylinders (yellow) will be in different diameters depending on the centre cylinder (yellow) size. So I can pull or scale the lids, cylinders into the dimensions I want, yet then I am left with my the parts in the Lid Mount & Screws all over the place (See image of objects scaled 0.5). 

My question is there a way to design the Lid Mount & Screws to be in a pattern that the parts stay in their respective groups yet the overall distance can be changed i.e. the Polygon and square is reduced or enlarged (see Lid Mount & Screws Patter)?

Hi @Anonymous 

I'm not sure if I have understood correctly, hopefully, this might help, in Fusion you have the ability to set up user parameters,  

please check out the video link below for more info

Changing the parameters seems like it could be the way I could do it, alas I have no clue how to bind the objects to the sketch pattern, see Sketch & object dimensions.

Hi@lee_sanders, yes that was useful and I will use that for other things I will do in Fusion 360 design.  However, I am trying to figure out how to word this in such a way to say that I am politely reminding you that my problem has not been solved.  I hadn't heard back from you so, I thought it best to be direct as my last message may have not explained that I still need help with this issue.  Cheers 🙂

Hi @Anonymous 

Thank you for reaching out, I'm glad you found the previous information useful. 

Is it possible for you to share your project? it will help the Fusion community better understand your request for help and hopefully provide a solution.

Thanks

Hi @lee_sanders,  Typical murphies law or some stroke of coincidence, I found what I was looking for in Fusion 360 tutorial by NYC CNC on YouTube not long after I wrote to you once more;

Fusion 360 Sketch Constraints Make Math Easy! 

Differently worth viewing especially if you want to add math constraints to your sketch and product designs, which is handy if you've watched any of the Kevin Kennedy's Fusion 360 demonstrations.

I have attached the screencast of my problem with the solution in the hope it helps others.

Cheers, Conrad.
