Appearance properties

There is an article related to Appearance‘s and a sample script installed with Fusion 360 that shows how to access Appearances from the libraries and assign them to objects in the model: “ApplyAppearanceToSelection.py”

In some cases you may want to drill down into the properties of the Appearance‘s which are used in the model, to find e.g. the texture that is being used by a given Appearance.
The following Python sample only shows how to access the name and value of the properties, but there are more than that available. If you look at the Property object in the online help file, then in the “Derived Classes” section you’ll see that quite a few other objects are derived from that. If you wanted to access all the properties then you’d need to handle all of them and check all their properties: http://help.autodesk.com/view/NINVFUS/ENU/?guid=GUID-db167e70-665f-4101-ba3c-3bcc88000fc7

You will get something like this:
