This option has been available for RVT and DWG files for a while now:
https://aps.autodesk.com/blog/advanced-option-rvtdwg-2d-views-svf2-post-job
The same has now been exposed for IDW files too and can be used exactly the same way.
Just add the advanced.2dviews: "pdf" option when translating the file:
{
"input": {
"urn": "your_model_urn"
},
"output": {
"destination": {
"region": "us"
},
"formats": [
{
"type": "svf or svf2",
"views": [
"2d",
"3d"
],
"advanced":{
"2dviews": "pdf"
}
}
]
}
}
