How to move fixed geometry into sketch origin?

I just want to constrain the center of the circle with sketch origin. It needs to stay fixed.

Edit your sketch and use the Fix/Unfix sketch constraint to remove the fixed constraint which is existing on your sketch.  You can tell it is there by the light green color.  You will find this sketch constraint tool on the toolbar and also by selecting the geometry and right clicking, the Fix/Unfix constraint will be on your right click menu. After this use a Coincident sketch constrain between the circle center and the origin.  Depending on what sketch and dimensional constraints you have between the tail hooked to your circle, how it will translate.

 

If you attach your model to a Forum reply post, the Forum users can show you directly.

Obviously i want to do this without unfixing the geometry. Unfixing and moving the circle disrupts the splines that are connected to it.

Unfix it and Move it as a group.

Then the spline gets messed up as soon as i move it. I made sure that i selected everything.

 

But even if it worked, how am i supposed to fix circle center to origin without messing up the unfixed spline?

You really could help by attaching your model as was asked in the beginning.

Here you go.  Used the Move command on the complete sketch as I mentioned earlier.  You did not specify which end so I chose one.

Thanks but the splines are messed up as i said. Also how did you put the center exactly at origin? It doesnt snap when you move the entire geometry. If you eyeball it next to origin then constrain it, that will change the geometry and will mess up the unfixed splines.

In the attached Screencast I prove to you I did not mess up your splines.  I took your model and superimposed mine on top of it and show you there is not difference.  Try it for yourself before you accuse me of changing your sketch.

Well splines did change and there is a difference. I can see it even in your screen.

 

I will show it to you. I have reproduced the exact same problem.

I agree with you, John's sketch is messing with the inside long spline, maybe others.

@jhackney1972  change body colours,

the 2 long splines are close to parallel as is if they are offset.

@prscustom if you want to move that sketch, it will need more constraint and dimensions.  Each spline point dimensioned with angle and length relative to the tube centre.  Al least all these construction lines locked.

 

Might help....

no it didnt help, and i had to continue my design like this

 

@jhackney1972

So no reply or solution? Arent you at least going to report this bug? Apart from acting offended. I should be the one who is offended as a customer for receiving such incompetent and rude response.

Please use the normal reply button under a post do reply to that post directly. The quick reply is always replying to the OP, which is unlikely what you want.

Autodesk Expert Elites are paying customers who, most of the time, enjoy helping other customers. That isn't even very hard to research. Perhaps it would have been prudent to do conduct that research before making a potentially foolish post!

 

Can you explain, perhaps in a screencast using the free Autodesk Screencast tool, how you created this sketch in the first place ?

One of the long curves does not look like a native Fusion 360 spline and I am wondering how it came to be.

Was my solution posted yesterday  “close enough”?

Just filter out noise in the discussion.

Thanks for the effort but no, its not acceptable. Because you used thicken to create the body. Sketch cannot be changed. And there should be no need to change because theres nothing wrong with the sketch.

 

And yes i started the sketch in fusion 360

I disagree with that assessment. Just because it was designed in Fusion 360 does not mean that there cannot be something wrong with the sketch.

Can you demonstrate in a screencast how you created the sketch. Maybe there's a bug to be discovered, but without the process to re-create the sketch there's little chance it can be reproduced.
