Change Part Material, Using a Python Script, Without Selecting The Part First?

Can anybody tell me if the following is possible?


Is it possible to change a parts "physical" material, using a Fusion 360 API Python Script, without selecting the part first?


For example, run the script and the parts material changes without any other input from the user. Say, for testing purposes only, change the parts material to "Steel, Mild"


Many thanks

It's certainly possible to assign a material using the API. The question is what do you want to assign it to?  You said you want to assign it to a "part", but a material can be assigned to a component and it can also be assigned to individual bodies.  If assigned to a component, all of the bodies in that component will inherit that material unless that body has a material specifically assigned to it.


The code below assigns the material "gold" to the component associated with the first occurrence in a design. You'll have to define how you'll know which part you want to set the material for.


def run(context):
        app: adsk.core.Application = adsk.core.Application.get() 
        ui = app.userInterface 
        des: adsk.fusion.Design = app.activeProduct
        root = des.rootComponent

        # Get the first occurrence in the assembly.
        occ = root.occurrences.item(0)

        # Get the component associated with the occurrence.
        comp = occ.component

        # Get the material library and the "Gold" material from it.
        lib = app.materialLibraries.itemByName('Fusion 360 Material Library')
        gold = lib.materials.itemByName('Gold')
        # Assign the material to the component.
        comp.material = gold
        if ui:
