Calling specific tool database in Script (Python)

MarcoNKE — Fri, 10 Apr 2026 10:41:29 GMT

Hi everyone,

i can't find a solid method to call my specific tool library, located in local folder in fusion database, in script code

i tried to use some exemple in API Help in Fusion but it doesn't work
can you tell me a way to do it as simple as possible?

thanks

Hi @MarcoNKE -san.

Is this the tool library you were looking for?

# Fusion360API Python script import traceback from typing import Optional import adsk.core as core import adsk.cam as cam def run(context: dict) -> None: """Entry point for the Fusion360 script. Retrieves the first tool found under the local tool library and prints its representative parameters to the debug console.

@MarcoNKE -san.

I was mistaken. Here is a sample that accesses the first tool in this tool library.
