Moving parts from assembly to subassembly

[MB_9236701]

Hi, 

I would like to make a new subassembly in the end of my model tree of top assembly. And I want to copy some of the components from top assembly to that new subassembly (just to pick the components I need to run some analysis) and than exlude it from top assembly. The top assembly is really big almost 2000 components and my current steps look like this: 

- Hide the components I dont need

- Choose part filter 

- Choose all the components I can see (components I need)

- And right click and Copy 

- Paste into new subassembly 

But the problem is that I cant copy all the components (or dont know the way how to do that), but only one and its really non effective way ? 

Do you know how to do that more effective ? 

Thanks

If STEP files would work for your analysis, then you could use the process listed above and only export the filtered component set as STEP from the top level assembly. Once you have the selection set defined in Creo create a layer to support filtering the state by layer to avoid re-picking all of the excluded components.

Assuming the components are placed in the assembly using a skeleton then you could save a copy of the top level and delete the models you don't want. This may not work if there are dependencies among components in the top assembly.

STEP files are nor suitable for me ... in that analysis I may do some small geometry changes , and I noticed that my method via Copy and paste is not as good as i thougt ... some parts which are not constraint as default are randomly pasted in the new subassembly and that costs time ... 

But thanks for your willingness

Without understanding of the assembly structure and the requirements for change from the new assembly, it is difficult to offer specific solutions. I would not dismiss STEP models as they can be modified easily with Flexible modeling features. 

If the Creo design has substantial design intent within the models and you will need to "flex" the new assembly then I would manually build the needed assembly needed for analysis and make sure that the structure of the assembly is capable of supporting the changes you need to make. It does not sound like there is a quick fix but hard to say without seeing the data set.

Just SAVE-AS a copy of your current top level and remove the parts you don't want.

@StephenW has the correct answer. You may want to read through the thread below:

Why not just make a simplified rep of the top assembly - that only has the components you are interested in analyzing.

Big thanks, I totally forgot on that option.

There is a command that may be useful.  Ensure all of the parts are structured as a sub-assembly in the model and are consecutive in the tree.  Select all of the parts, RMB, select the Move to New Sub-assembly button (this command is not found in the ribbon out-of-the-box), and complete the Create Component dialog box.
