Assembly/joints problem

[Anonymous]

Hi,

I am trying to import components/bodies and I want to fix them with plane/sketch from an anothen component.

If you see my file, I placed the component 2 and 3 where I place them  with move. But I want them depending my sketch so if I change the length it will change.

Is it possible to do that with assemble joint or any other idea. I want to make it the more parametric I can. 

Thank you

You can use a joint between a component and a sketch point.  Your components appear to need a revolute joint, so it would be best to locate a single non rotating component, then use rigid and rotating joints to position the other components.

Hi,

Thank you for your answer,

I do not understand what you mean with''so it would be best to locate a single non rotating component''. Is it possible to send me a file?

Another way to say it is: Start with a stationary component.  Ground that component.

In your file there are two components which seem to need to be rigidly attached to other components as well as rotate around a shaft.  Start with one of the non-moving components.

There isn't enough information in your posts or in the file to determine what needs to be attached to what.

There is however enough information in @Anonymous's post to conclude that he hasn't watched any of the assembly tutorials in the Support and Learning section. If he did, he'd know what to do 😉

Hi,

I don't want to ground the component because if I change my sketch, the one which is grounf will not follow the sketch.

I am trying with sketch because I am not able to use plane.

The component to which one of the existing components attaches needs to be created first.  This component's size will be controlled by a sketch which in turn will control the location of the existing component(s).

Hi,

I did watch all the tutorials but I still don't know how to do it. I have to think fusion,I know that I missed something and don't get it yet. 

I will try to explain myself. It's not easy for me en english.

I have a body. From this body I will design my sketch. A rectangular. In the corner of this reclangular I want to bring a component. The corner of the rectangular is the center of the diameter of the hole. the smallest line of the rectangulanr is colinear with face of my component.

The edge of my component is parallel to the axe which is in angle.

SO in the end my component will be fix but depending of my 2 sketches.

I looked at the file you had attached to your first post. Your sketches are not fully defined (constrained and dimensioned).

Do that first and then we can see about the rest.

You might want to consider looking into Fusion 360's R.U.L.E #1

This is just an example, you can put the dimension you want.

The only important dimension are the rectangular.

You're not quite getting what I am saying, so let me be a bit more blunt!

Before continuing you should at least understand the difference between components and bodies.

@RatibaO3D: I resonantly learned that you can join components that just have a sketch and no body. If this is what you try to achieve, than you should do it this way:

You can use the attached design to test things out.

I hope you can now recognize what @TrippyLighting meant when he pointed out the Fusion 360's R.U.L.E #1. In the most cases you want to create a component first and than the sketches, bodies etc. inside the component. I can understand why you want to structure things by having sub components, but (as a beginner) my experience is, that it's easier to keep things as simple as possible. So I wouldn't place components in components that fast.

Hi,

Sorry for the delay, I was busy yesterday.

So here is my error? correct me if I am wrong. I considered the first body as a component. As when we begin we are creating a component, so I thought that if I bring another component in it that  will work all components, that's my error?. When I see your video, you begin with creating a new component so when you create/bring other component, they are all components.

I did see the rule 1 and the lessons but I was still missing that notion for the first component.

Sorry, I can seem hopeless 😉

Thank you all for your help

I had more or less the same problem to wrap my head around how to do things the proper way. And it was difficult to me to understand why things are like valuable members of this community told me. And knowing rule number one also was something I learned here 😉
