Changing position of the 3D component after a rectangular pattern is created does not move the rest of the objects

[Anonymous]

Hello,

I am new to Fusion 360 and I'm looking to better understand how to update the first object in my rectangular pattern so that all objects in the rectangular pattern update their position after the base object moves. 

Here is what I'm doing:

1. I bring in a 3D object that is an assembly of two parts. 

2. I place it in space

3. I create a rectangular pattern for 3D objects  on a 4x4 grid  

4. They spread out on the grid and look great! 

Now, I wanted to move the base/anchor component AND have all of the objects based on that to move with the updated anchor point.

5. I move the base object .

6.  After moving the object the rest of the rectangular pattern stays in the same place and does not update to follow the change in location of the initial anchor component.  

7. I go to edit the rectangular pattern to adjust the object that is the base object 

8. It then shows the same object, but in the old position 

9. I could not find a way to select the moved base component.

How can I move the anchor object and have the other object update their position automatically? 

Any thoughts or help here would be greatly appreciated as right now my only solution is to delete the pattern and recreate it... and this is takes a long time and has other side effects on the overall project. 

Thanks,
Brett

Put the timeline marker, left side of the pattern icon, 

make the changes. Send timeline marker to the end.

all should update. 

Or set set up all that make the pattern, as a Rigid Group, - this group will Move as one, after that..

Might help....

@davebYYPCU,

Thanks for the ideas.

1) rolling back the time line:

  a) I rolled back the timeline 

  b) I then moved the object 

  c) I moved the time back and the initial object moved back... *shrug*

2) Ridged body - I still need to try that. 🙂

I've attached a video showing the issue

Maybe it has something to do with how I initially put the object on the board?

1. Ground the PCB, or create an as-built rigid joint between its origin and the top-level origin. That will lock it in place.

2. I use a joint to properly locate the terminal on the PCB.

3. Create the pattern. The component pattern only creates the instances, but they are not joined to anything and can be dragged out of place. So use a rigid group joint and assemble the patterned instances to the original terminal.

P.S. in the future, please use the Autodesk Screencast tool to create recordings.

@TrippyLighting,

Thank you for the info. 

At first read, homely, I have to say, that is a lot of work vs. the pattern being anchored to the initial object. 

I will give that a try.

Thanks.

Before moving the timeline to the right, Fusion placed 2 tool icons on the end of the Tool Ribbon, Capture position, and Revert.  Capture Position is required before moving the Timeline, and when not done, the Revert is default.

However while this answers the question, a better workflow is to Joint the first item, and edit the location inside the joint, without a Move command.

Hi @davebYYPCU,

Thank you for the thoughts on the joints... here is what I tried :

1. created a sketch to hold the location of the "as built" join on the surface

2. I then brought in my STEP model

3. I oriented it

4. I then attempted to use the Joint command 

5. I selected the center of the audio jack 

6. I selected the "as built" joint

7. only part of the step models moved

9. I undid that joint 

10. I attempted to ensure the model is "rigid group" 

11. I then tried the joint command again 

12. only part of the step model moved over.

So I'm not sure what I'm doing wrong here..

Any thoughts would be appreciated.  

Here is a video of the above:

I'll attach the step partfile as well.

Thanks,

Brett

Note: the mouse is of in the recording because I run a lower screen resolution and use scaling on windows sorry about that, i'm not sure why the recorder does not to the correct ting there. So the mouse pointer is off but I am hitting the correct menus and objects.

That is preview behaviour, pressing cancel does not finish the manouvre,

press Ok, for Fusion to finish the job.  (Common for newbies but you learn this one pretty quick)

You don't need the sketch or joint disc, - select the corner of the plate, and lower down in the dialogue, you can insert the dimensions of the sketched x y coordinates, if that helps (before hitting OK)

Files were not attached, will do that with email replies, you need to be in here for them to attach.

@davebYYPCU, @TrippyLighting,

Thank you both for the help!

The rigid body worked great!

Getting joins connect worked great as well!

So all is well and I really appreciate the help!

Thanks,

Brett
