I have trained a model small ranger random-forest model and saved it using saveRDS on R version 4.1.0. Now I need to run it on a website server that operates at 3.6.0 and doesn't accept ranger library to be uploaded. How can I transform the ranger object into a form that couldb

According to https://github.com/wallabyway/OTG-client-sample, a new OTG format for the forge viewer has been released and it looks like it has siginificant improvement in performance as opposed to the traditional SVF format.
Currently,we are using model derivative API to translate RVT/NWD files to SVF and download it to our local machine using the extractor from the following link:
https://github.com/cyrillef/extract.autodesk.io
The question is that how do I to translate the model into OTG format and load it locally?
Thanks in advance!
As of now (end of August 2019), the OTG file format can only be obtained via a manual post-processing step through a series of unofficial API calls. However, we're planning on including the OTG output as part of the standard Model Derivative translation. Stay tuned to the blog and #AutodeskForge for updates!
I need to code a Python programme that uses a Graphical Interface with tkinter to choose an Excel file and read from it different columns?
I'm trying to translate Revit file that contains both 3D and 2D geometries. I've verified that the file contains proper 3D geometry, by opening it in revit 2019 and visualizing it through 3D viewing mode.
However, when I pass this file into model derivative process, it only creates 2D derivative.
Before translation process, I've tried to set default view of the revit file as '3D' instead of 2D drawing file, which didn't work.
I've also tried making a translation POST request with formats as 'svf', and views as both ('3D', '2D'), and ('3D' only), which both failed.
However, all these attempts didn't work, and when I inspected the manifest from the file translation, it seems like that 3D geometry is completely missing. I think that there is a unhandled exception in Model Derivative process that fails to extract 3D geometry in our particular forge model file.
If you need URN of the file / actual file, please let me know.
Thanks in advance.
- EDIT
UPDATE:
I've confirmed that the default 3D view is named as {3D}, default name set by Revit.
What is the name of your default 3D view?
The default name is "{3D}", I believe.
Maybe the translation process does not pick it up if it is named differently.
Afaik, the one and only way to specify the views for the translator to process is by using the Collaboration for Revit or C4R BIM 360 Team tool to select the views to publish to the cloud.
I've seen some examples of high quality and detailed models that works for the Autodesk Model Derivative. Some example are Dotty, Dasher and Fusion Race Car. Dotty is actually amazing.. even has some reflection added in there.
So, to achieve this I would need to upload the textures and the materials with my model. I've tried to reproduce the guide telling me to create a ZIP containing of the OBJ, MTL and PNG. First of all, to be sure I am on the correct path when I am testing out different workflows: is OBJ the only format that can be uploaded with custom materials/textures? I know that I can add standard materials to rvt, fbx, 3ds etc, but I do not have a clear idea on how to upload custom materials/textures.
Could you kindly give me a step-by-step how to get the best possible visualization of the uploaded models? Thanks a lot
Models from Fusion 360 uses the built-in material library, in the case of Fusion Race Car you mentioned. The Dasher sample uses a Revit model of a "well-designed" model in Revit, but no custom materials. Don't have much info on the Dotty format, but would consider the direction of obj or rcp (Reality Capture or point cloud) files, both can have texture.
For a custom material, OBJ is the best route as of now, allowing you to include your textures. As far as Forge, the translation is exactly the same: upload the zip with all files and post a job with rootFilename pointing to the .obj file.
I would like to build a CNC manufacturability analysis app using Autodesk Forge.
Setting the computational geometry algorithms aside, what kind of geometrical data can I extract from CAD files using this platform? also, is there an existing app I am unaware of?
Thanks
Depending on the input file format you can convert to different other formats:
Supported Translations
Though it's not obvious from the above list, all input formats support conversion to OBJ format, which can also be done at subcomponent level - so you don't have to export the whole model to OBJ.
Here is a sample that lets you access your files from A360 and convert them into whatever format is currently supported for them:
