Uploading linked Revit models to Autodesk Forge - autodesk-forge

Question

I've been trying to use the Post references (https://developer.autodesk.com/en/docs/model-derivative/v2/reference/http/urn-references-POST/) to set up the reference between two files in forge but although I get a message "success" as result when I try it on the forge viewer I still see the files separately even after I translate the models. Has someone been through the same issue?

Answer 1

Without seeing you code it is hard to tell what is happening. Below I copied my bash script code which references/translate an obj with material and texture.
Au.obj
+- Au.mtl
+- Au.jpg
After upload, I got these
idObj="urn:adsk.objects:os.object:cyrillejcrja/Au.obj"
idMtl="urn:adsk.objects:os.object:cyrillejcrja/Au.mtl"
idJpg="urn:adsk.objects:os.object:cyrillejcrja/Au.jpg"
the code to set references, now
urn=$(xbase64encode $idObj)
job='{
"urn": "'${idObj}'",
"filename": "Au.obj",
"references": [{
"urn": "'${idMtl}'",
"relativePath": "./Au.mtl",
"filename": "Au.mtl",
"references": [{
"urn": "'${idJpg}'",
"relativePath": "./Au.jpg"
}]
}]
}'
response=$(curl -H "Content-Type: application/json" \
-H "Authorization: ${bearer}" \
-X POST ${ForgeHost}/modelderivative/v2/designdata/${urn}/references \
-k -s -d "${job}")
Here is got a reply like below which only means that the references are registered.
{
"result": "success"
}
Now, I do this to translate the obj and use the references
urn=$(xbase64encode $idObj)
job='{
"input": {
"urn": "'${urn}'",
"checkReferences": true
},
"output": {
"formats": [
{
"type": "svf",
"views": [
"2d",
"3d"
]
}
]
}
}'
response=$(curl -H "Content-Type: application/json" \
-H "Authorization: ${bearer}" \
-H "x-ads-force: true" \
-X POST ${ForgeHost}/modelderivative/v2/designdata/job \
-k -s -d "${job}")
Note the "checkReferences": true, as documented here.
Now, I can wait the translation to complete and see the result in the Viewer.
For reference the xbase64safeencode function used above
function xbase64safeencode () { local id64=$(echo -ne $1 | base64 $wrap_arg | tr -d '=' | tr '+/' '-_'); echo $id64; }

#Cyrille, this is my request:
curl -X 'POST' -H 'Authorization: Bearer eyJhbGciOiJIUzI1NiIsI' -H 'Content-Type: application/json' -v 'https://developer.api.autodesk.com/modelderivative/v2/designdata/{urn}/references' -d
'{
"urn": "urn:adsk.objects:os.object:bucket/non-existent.rvt",
"filename": "",
"references": [
{
"urn": "urn:adsk.objects:os.object:bucket/non-existent.rvt",
"relativePath": "",
"filename": ""
}
]
}'
I got as result:
'{
"result": "success"
}'
The point is I'm getting success as a result even when I do not have the specified file on the server, so I'd suggest few server-side validations, for example, when a model has been translated once we can't set as reference right so it should at least return an error. Thank you and I hope this helps.
