Import catia parts retaining position relative to previously imported assembly

Benjamin_Dellal

Hi,
I am in the process of migrating our Catia model into onshape. I will handle the release process in onshape, but will have to modify and re-import some existing parts in Catia along the way.

• I imported a Catia assembly file containing all parts in the correct orientation
• Now I have to change a few parts in catia and re-import only these few parts into onshape. I have to retain their position relative to the originally imported assembly. 
• For that, I can partially export the catia top level assembly and re-import into onshape. Now, I am adding the assembly containing my few updated parts to the onshape top level assembly
• The problem: I need to move the parts out of the re-imported assembly into my onshape top-level retaining their position

Dragging parts in the tree does not work. I get the error: "Operation cannot be completed as it would modify a saved version"

Any thoughts on doing this in a different way or fixing my workflow?

@Benjamin_Dellal your last point is a little confusing, maybe a screenshot of the assembly list will be helpful or sharing a link?

If you import the sub-assembly from catia into Onshape as 'flattened' you will still maintain the parts relative positioning but not create a subassembly (all parts get placed into a part studio). This will allow you to select the parts needed to insert into the top level assembly (or appropriate subassembly) without having a random subassembly to deal with from the import action.
