Programmatically Change Material Properties in Process Material Library

I know I can modify basic properties like Density, etc. by retrieving the material from app.materialProperties, but these material objects do not seem to have nesting properties like Length, Width, Frame width, Item separation. Is there another way to access those properties?

@jon6CUA5

I don't have a solution for you. It is not obvious for me from the Fusion API how to get properties. So, how do you access various properties from materialProperties and appearanceProperties. The only property I know how to get is appearanceProperties.itemByName('Image'). Are all property names in the from Fusion material dialog as seen by the user? For example, I got the "Image" name from the "Material Editor" dialog. If so, how would one handle names that appear in sub dialog? I hope all prop names are in a flat data structure.

Hi @jon6CUA5 .

We have created a sample that dumps the materialProperties of a selected body.

# Fusion360API Python script import traceback import adsk.fusion import adsk.core def run(context): ui = adsk.core.UserInterface.cast(None) try: app: adsk.core.Application = adsk.core.Application.get() ui = app.userInterface des: adsk.fusion.Design = app.activeProduct root: adsk.fusion.Component = des.rootComponent msg: str = 'Select' selFilter: str = 'Bodies' sel: adsk.core.Selection = selectEnt(msg, selFilter) if not sel: return body: adsk.fusion.BRepBody = sel.entity material: adsk.core.Material = body.material dump(f'-- {material.name} : {material.id} --') props: adsk.core.Properties = material.materialProperties dump('(Property.name : Property.id : Property.value : Property.isReadOnly)') for idx in range(props.count): prop: adsk.core.Property = props.item(idx) dump(f'{prop.name} : {prop.id} : {prop.value} : {prop.isReadOnly}') except: if ui: ui.messageBox('Failed:\n{}'.format(traceback.format_exc())) def dump(s): adsk.core.Application.get().log(f'{s}') print(s) def selectEnt( msg: str, filterStr: str) -> adsk.core.Selection: try: app: adsk.core.Application = adsk.core.Application.get() ui: adsk.core.UserInterface = app.userInterface sel = ui.selectEntity(msg, filterStr) return sel except: return None

It seems that each material has different properties that it owns, so I felt that I had to provide an itemById method and an itemByName method.
