Description

Even though there is no longer a way to enter this information when uploading a model, API calls such as https://3dmr.eu/api/info/4 still return information for the rotation, translation and scale properties.

Ideally, such a change would be rolled out at the same time as an update to the 15 existing models which use non-default values for these properties:

2: scale=0.02
3: rotation=320.0 translation=[50.0, 9.0, 0.0]
4: rotation=45.0
5: scale=50.0
7: rotation=308.5 scale=0.034 translation=[610.0, -50.0, 0.0]
9: scale=0.7
10: translation=[1.0, 8.0, 0.0]
12: translation=[-6.11, 2.82, 0.0]
13: translation=[5.58, -1.93, 0.0]
14: translation=[-0.26, 3.31, 0.0]
15: rotation=180.0 translation=[0.0, -8.5, 0.0]
22: rotation=357.9 translation=[0.54, 22.79, -3.43]
27: scale=100.0
32: rotation=217.0
35: rotation=180.0

Given that the number of affected models is manageable, I might be able to update them manually if necessary.

Contributor guide

Research direction
Modify the API endpoint to stop returning rotation/translation/scale fields. Then update the 15 models to remove those properties.
