I want to convert the native cad file (.prt ) to step file using fusion 360 in python.In fusion API, i couldnot find import for the .prt file but have only few files. Could you guide me how can I translate the .prt file programtically using python with the help cloud API?

Many thanks

Hi @s.chand6RXFT .

There are not many formats that can be directly converted by the Fusion360 API.

https://help.autodesk.com/view/fusion360/ENU/?guid=GUID-GUID-DA509909-1E13-48F1-8235-744BA6B94CBA

Therefore, you must upload your data to the cloud, open the document, and then export it.

I have not tried this, but @BrianEkins has created a sample.

This year, the Application.dataFileComplete event was added, so it may be a little easier to tackle.

https://help.autodesk.com/view/fusion360/ENU/?guid=GUID-049CC6A8-10A5-47AD-B5DE-10B29721548A

However, I think it would be difficult to get the timing of when the document is finished opening and ready for export.

Hi,
What kind of Fusion 360 license do you have?
The Personal license doesn't allow to open .PRT filetypes, which is required to export it then to other format.
Check this first, before you invest some more time in the script development.

Regards,
Jorge

@s.chand6RXFT .

I have created a sample add-in and have attached it.

Since we do not have the SLDPRT file at hand, we borrowed it from here.

https://grabcad.com/library/dowel-pin-din-7-1

When the add-in is executed, it performs the following processes
・Upload file
・Open document
・Export with Step file
・Close document
・Delete from data panel
・Closing the add-in

The Step file is created in the same folder as the SLDPRT file with the same file name.

@s.chand6RXFT .

I do not know how to do that.

You should consider installing conversion software.

Due to the automatic process require my program, i choose the model derivative api for file translation prt file to step file. I am following the following tutorial.

https://github.com/Autodesk-Forge/forge-tutorial-postman/blob/master/ModelDerivative_01/instructions/task-3.md

I can get token,create the bucket and upload the file in the cloud. But, when i tried to do translation work i am getting the error.

my source file is 827-9999-906.prt which i download from interne
The code is as shown below:

But i am getting error :

Does Modelderivative Api doesnot support step derivative format??

how can i achieve the step file from prt file ? Waiting for your reply.

Many Thanks

I think you'll have better luck asking your question on the Forge forum on Stack Overflow.

https://stackoverflow.com/questions/ask?tags=autodesk-forge

What you're trying to do now has nothing to do with the Fusion API.
