How can I change the BOM behavior of an assembly through the API?

Michael_Ursuliak

I have a lot of drawings from my top assembly, I am kind of new to this API thing.
I would like to get a list of assemblies from the top assembly, use that list to go to the respective studios,
and then change the BOM behavior to Components only.

Is there a way that i can do this with the API? 
I took a look  through glassworks but i admit that i don't understand much of it.

You can get the current assembly using the endpoint


/assemblies/d/{did}/{wvm}/{wvmid}/e/{eid}


In the assembly definition, the field "subassemblies" gives a list of each subassembly.
Each subassembly has a documentId, documentVersion, and elementId.
These three fields will locate the assembly studio of each subassembly.

You can then use the endpoint

/metadata/d/{did}/wvm}/{wvmid}/e/{eid}

to update the metadata property for subassembly bom behaviour.

With a body similar to (replace href with your document href):

{

   "items":[

      {

         "href":"https://cad.onshape.com/api/metadata/d/7db81dbba1549bf0065c3e05/v/50faf4b403c0933f922ae27b/e/acb47fda0ea3cb66ecff6069?",

         "properties":[

            {

               "value":"2",

               "propertyId":"57f3fb8efa3416c06701d633"

            }

         ]

      }

   ]

}

Luckily, this field is editable in versions, so you can update the field without having to find the workspace and create a new version.
The values are 0,1,2, where 0 is assembly and components, 1 is assembly, 2 is components.
