Cannot move adaptive part (Leaf spring)

Anonymous
Not applicable

I have this assembly:

 

 

https://www.dropbox.com/s/3zis5iez0vodmql/Screenshot%202015-03-03%2019.55.12.png?dl=0

 

 

The leaf spring is adaptive (none of the other parts are).

 

The when I try to move the lever that the spring is resting on it is locked. If I turn off adaptivity for the spring I can move the lever. When I turn adaptivity back on the spring updates to the new position. Is there a way I can make it update on the fly and allow movement of the assembly without turning off adaptivity.

 

Thanks!

HI!

 

 

Yes is possible, but depends how you have constrained and create the parts.

 

Can you post the files Here?! Without seing what's going on in the assembly we can´t tell you much.

Adaptive parts do not update on the fly by dragging the assembly.  You will need to set up a constraint to move the assembly either by driving that constraint, setting positional representations that override that constraint to different offset values, or just manually changing the constraint offset.  Since the shape of the leaf spring has to be re-calculated for every position, even driving a constraint with adaptivity on can be slow and jerky, but it beats turning adaptivity on and off.

I expected this might be the case, as I tried playing around with the scisors example and could only get it to move by driving the constraints. 

 

I'll have to work out the limits of movement and use the drive tool.

HI!

 

Not exactly.

 

You can edit the spring in assembly context and copy a reference from the other part, Therefore, if you move the other part, reference will change and therefore, the spring will change accordingly.

 

You can move manually the system or with drive constraints or with limited constraints.

I think you are describing what I did. From the assembly I referenced the edge of th lever for the spring to meet. However the lever cannot be manually moved while the spring is adaptive. 

 

At least I couldn't get it to move.

You are more likely to get help if you attach your assembly here or at A360.

Didn't you already supply that url?

I don't go to 3rd party sites.

Bad experience with stuff installed in the background that I did not authorize.

 

Ever notice how many posts there are here by people wondering why they have trouble with their machines....

Keep your professional machine clean.

 

Have you installed Service Pack 1 and Update 2?

Different link, it is just a dropbox link to the zipped assembly. I have also attached it to this post.

Hi!

 

Ok... it's perfect!!!

 

If you read again my previous post, you will understand.

 

Check the model attached... now you can use a drive constrain to have a more fluid movement or even make a video.

Maybe something like this?

Thanks, it seems to work!

 

Is there a difference between copying a reference and projecting a geometry (from another component in assembly view)?

 

Trying to find some tutorials on referencing so I can replicate what you did.

 

Thanks!

That is what I am hoping to achieve, also allowing the lever to be dragged manually and for the spring to update after the movement (or during).

 

I have tried to recreate the way

In my experience, reference sketches loose more often the links than copy surfaces, that's it.
I think that the dimension you had was stoping the process, (and also wasn't real case: the spring bends, not grow or shrink).
Why you can't reproduce? where are you stuck?

 


JD, i'm trying to insert screencast videos , but without success... How you do it?!!!

I am unsure how to copy a surface.

 

Thanks,

One of the issues brought up in this thread as that you have to apply constraints to get Adaptive parts to update. Adaptive parts don't update on-the-fly by dragging in the assembly. But it would be great if they did, something like this:

 

Adaptivity Correct GIF.gif

 

There's no reason Adaptivity shouldn't work like that (I explain why in detail here).

 

If you agree that Adaptivity should work as shown in the above video, please help get that functionality implemented by voting for the following enhancement request in the IdeaStation:

 

Vote here for Adaptivity to work as shown above: Fix Adaptivity (make it truly adaptive/flexible)

 

Thank you!
