Autodesk FORGE: Get Geometries - autodesk-forge

Good morning. I am trying to extract geometries with the autodesk forge tutorial and I have a problem.
https://forge.autodesk.com/en/docs/model-derivative/v2/tutorials/xtract-geometry-from-source-file/task5-extract_geometry/
First I do the extraction for some specific object ids and it works correctly, I download the file and read its geometries. The problem is that if I change the object ids from step 1, in step 2 of verifying the job, it keeps returning the references from the first time I used the job. It's as if it doesn't refresh the new object ids. What could be happening?
Thanks in advance.

In response of step 1 with new ObjectID's, you will get the new URN "URL_SAFE_URN_OF_SOURCE_FILE>"..
Use this URN in Step 2 to check status of Job

Autodesk Forge Indexes API: issue with querying large files

I am working on a tool that would allow the user query the properties of Revit model elements stored on Autodesk BIM360. I am using Forge indexes API and implement a workflow similar to the one documented here.
It works great for small models, however it starts crashing on large ones. Querying the entire property index with Get Index Properties results in error code 0, while applying any query to the index (Post Queries) returns a query in state = FAILED, with the error as follows:
type: "RuntimeError"
title: "AmazonS3Exception"
detail: "The character number in one record is more than our max threshold, maxCharsPerRecord: 1,048,576"
This seems to be related to the issue explained in this blog post, namely querying the entire json collection as a single object by calling from S3Object[*] as stated in Model Property Service Query Language Reference. Is there a way to fix it on the API caller end or is it a bug on the side of Forge? Help will be more than welcome. Thanks!

Forge Viewer shows different data from Model Derivative data on IFC file

This is a process that I've always used. First I call the bulk data from model derivative for further structuring. But this time the derivative data is confusing. Because when I use getProperties from viewer it shows external id with expected format(0/0/0/145/79) but when the same element is called from derivative api, on the field of external id, ifcGUID (11h5ts$FhghhDGbOs) is written.
In short I can not get external id of element from derivative Api but it can be found from viewer.
What could cause to such confusion ?
Today I have uploaded the model with SVF format instead of SVF2 and it looks like everything is working fine and as expected. But I think this topic needs further investigation.

Autodesk forge SVF2 dbid

I configured our viewer to use SVF2 format yesterday as per these instructions: https://forge.autodesk.com/en/docs/model-derivative/v2/developers_guide/notes/
I have observed that when selecting a node in the model, we get different Id's from SVF vs SVF2.
I usually pull the metadata and properties using the following GET calls:
https://forge.autodesk.com/en/docs/model-derivative/v2/reference/http/urn-metadata-guid-GET/
https://forge.autodesk.com/en/docs/model-derivative/v2/reference/http/urn-metadata-guid-properties-GET/
It has been mentioned here that the SVF2 Id's are computed differently, is there a way to get the Id's of a SVF2 model without loading it into the viewer first?
Apologizing for any inconvenience had caused. This is a known issue that our engineering team is evaluating, and we're hearing customers' voices. Could you consider providing your use case to SVF2 objectId with more details and the paint points you might have if the objectId between GET properties and viewer are inconsistent? Currently, there are two workflows that we're interested in as the below. Could you kindly point out which one your workflow is?
Normal workflow (GET properties -> Viewer), e.g., get dbIds(objectIds) by filtering properties with some conditions with GET properties, then partial load objects with LMV.
Reverse workflow (Viewer -> GET properties), e.g., select some objects in LMV, then post back to GET properties to get specific properties to store in DB.
Note. If the information you want to share cannot be posted publicly, please send it to forge[DOT]help[AT]autodesk[DOT]com instead. Meanwhile, please remove any confidential information and personal data from anything you want to share with us before sending it out.
Update 2021/07/21
Just to let future devs know that SVF2 is now GA, article is here.

DerivativesApi.GetModelviewProperties for subset of properties

The model viewer has the ability to get properties by passing a filter: viewer.model.getBulkProperties(dbIds, ['externalId', 'Category'], function) where we can limit the results to just the two properties 'externalId' and 'Category'.
It would be a huge benefit for us to have this same filtering capability from the model derivative api:
https://developer.autodesk.com/en/docs/model-derivative/v2/reference/http/urn-metadata-guid-properties-GET/
We have Revit files with 40,000+ parts, and it can take over 15 minutes to query for properties, but we are getting far more data than we need.
it is a reasonable enhancement. I logged it as an internal ticket DERI-4610.
If you have used Extractor to download the whole SVF dataset to local , you could try with extract the properties from properties.db (the other post tells more). This is a lite sql database which is actually used by Derivative API on Forge cloud. I'd think there is some smart ways to filter the specific properties by the db file.

Export entire Logical Data Model from GoodData

In this https://developer.gooddata.com/article/data-modeling-api there is a logical data model and its corresponding JSON. However, I can't seem to find out how to extract JSON from a logical data model via the REST API. Is there a way to do this other than using the single load interface (which would be very inefficient)?
For the record, my end goal is to make a tool that extracts that JSON (which would be in dev), then post that to the ldm manager2, and then apply the suggested changes through the returned MaQL to production. Any help is greatly appreciated
Currently this works only for Getting or Updating the entire Project. Anyway you can GET all model definition by simple API call. See the documentation:
http://docs.gooddatadrafts.apiary.io/
There is a GET request which is asynchronous. You can build some logic on the top of that on your end. You can get all models, store per datasets information, but at the end you need to POST the "final version" and all updates will be applied.
Let me know if I can help you with anything!
