Question

How to bring assembly component coordinate system into another sub assembly using copy geometry

Hello,

 

I have created the master/top level assembly with the required subcomponents/parts.

 

Now i want to create an another sub-assembly which i need to bring in the coordinate system of master assembly subcomponents as external copy geometry/publish copy geometry. 

 

When i try to use copy geometry, creo was not allowing me to select the coordinate systems from the multiple components (allowing to select one component per copy geometry) which means i need to create the multiple copy geometries to bring in individual subcomponent coordinate systems into my sub assembly. 

 

is there any alternate way to collect and bring all the subcomponents coordinate systems into my subassembly using one copy geometry or publish copy geometry ? i don't want to create multiple copy geometries.

I do not think what you are asking for is possible. A skeleton model would allow for the copy geometry to include multiple datum features all copied from the skeleton using one copy geometry feature. One of the purposes of the introduction of skeleton models was to control the locations of interfaces between components.

 

About Skeleton Models in Top-Down Design (ptc.com)

 

Add a skeleton to the top-level assembly and define the csys etc. in the skeleton needed to control the positions. You can then publish the any info from the skeleton as required when creating new models.

Yes, I think so (if I understand your ask).  Try this:

1) bring in the new sub-assembly into your master assembly.

2) activate this new sub-assembly

3) use shrinkwrap feature "Manual collection" option to gather the coordinate systems of the master assembly components:

If shrinkwrap works for this (it should) that is a good workaround to leverage your existing models. Shrinkwrap also provides for filtering what is referenced by the feature.

 

I probably would not default to using this as SOP without putting some thought to it. It is used in routed systems design to get relevant routing references propagated through the design space.
