Configuration is ignored when trying to export drawing via API?

gerco_flonk

I have this very simple example:

https://cad.onshape.com/documents/1924bf2dae91de85359f60db/w/122fe50cf8f782da3f636032/e/9af2fef32d1f0656726a35bf

It is a cube with three configuration variables that control its size. The link points to a simple drawing from one of the sides. I want to export this drawing to DXG (via the API) using the “configuration” option to modify the cube at the same time. See the code below that reproduces the problem (replace acces_key and secret_key).

What I expect: that the “configuration” parameter in get_drawing() is used when exporting the drawing. This way the exported DXF has the dimensions of the configuration.

What actually happens: the result of get_drawing() (and then retrieving the dxf via the response > href > resultExternalDataIds) is a dxf with the drawing in whatever the dimensions are present at that time in the onshape drawing, ignoring the configuration parameter.

As an example I added a second request, massproperties().The configuration parameter in this request actually does take effect (volume in response is bigger if I input a bigger width in the configuration).

I’m wondering what i’m overlooking and what is needed to make this work.

Thanks in advance!

import base64
import requests

access_key = 'access_key'
secret_key = 'secret_key'


credentials = "{}:{}".format(access_key, secret_key)
encoded_credentials = base64.b64encode(credentials.encode()).decode()

headers = {
    'Authorization': "Basic {}".format(encoded_credentials),
    "Content-Type": "application/json;charset=UTF-8; qs=0.09"
}


def get_drawing(headers):
    url = "https://cad.onshape.com/api/v6/drawings/d/1924bf2dae91de85359f60db/w/122fe50cf8f782da3f636032/e/9af2fef32d1f0656726a35bf/translations"

    payload = {
        'storeInDocument': False,
        'formatName': 'DXF',
        "configuration": "width=900"
    }

    response = requests.post(url, headers=headers, json=payload)
    print(response.text)


def massproperties(headers):
    url = "https://cad.onshape.com/api/v6/partstudios/d/1924bf2dae91de85359f60db/w/122fe50cf8f782da3f636032/e/5a1abb051284203d02770879/massproperties"
    params = {
        "configuration": "width=600mm",
        "rollbackBarIndex": "-1",
        "massAsGroup": "true",
        "useMassPropertyOverrides": "false"
    }

    response = requests.get(url, headers=headers, params=params)
    print(response.text)


get_drawing(headers=headers)
# massproperties(headers=headers)

Drawings work a bit differently from part studio and assemblies.
Instead of configuration being set at the drawing level, its set per view, and it directly edits the drawing.

In order to export a configured drawing, you need to update each view in the drawing, and then export the result drawing.

You need to use the end point:
/api/appelements/d/../w/.../e/../references

And update the configuration of each reference.

Alright, thanks for your reply! I will have a look into it.
