Restructuring a multi-level assembly into a single-level assembly

Hello community,

Is there an automatic method for restructuring a multi-level assembly to a single-level assembly?

Thanks

AFAIK there is nothing available out of the box that would do this in an automated fashion. Starting with Creo 8 inspirable assemblies were introduced which may be relevant to your needs so investigate that functionality if you have not already done so.

Shrinkwrap functionality or export/import can be used to flatten assemblies, but I am doubting that these options would meet your stated goal as the results here are not fully parametric Creo data structures but dumb geometry representations.

Hi @tbraxton and thanks for your reply!

I just wanted to point out that your response doesn’t really address the specific need I raised in my question. Rather, it confirms that Creo currently lacks a built-in automated method for flattening multi-level assemblies into a single-level structure while preserving parametric relationships.

After further investigation, I realized that the Reconstruction operation best suits my needs. I selected all the components and chose the target assembly to move them into.

Also, I’m not sure why Inspirable Assemblies were mentioned—they seem to serve a different purpose and don’t appear to be relevant to the restructuring functionality I asked about.

I think you meant to say "Restructure", not "Reconstruction".

Good catch, @ArnoldCollett - thanks for pointing out that typo!
Much appreciated 🙌
