It is possible to recover a grain direction in a painting from a wood texture.
That is to say, to specify a little more, that if the grain of the wood of the texture is in the length of the piece, we retrieve the information in the table with the comment "Long Grain" for example.
What you are asking for is not possible since the structure of a component is not information used in the CAD module. Only in simulation the internal component is used.
The volumes in SW do not at any time have the notion of fiber, they are wireframes whose outer surfaces are colored. And again, this is just an individual part, if you put a wooden structure on an ASM set, you will have anything.
The problem with textures is even worse because they are just images that are plastered on an entire volume (an individual piece). In addition, they don't even paste in reference to the foreground and you can't change this reference either.
So you can't retrieve any information from the images. On the other hand, if you define inherent properties of the part, then you can reuse it. But from a visual point of view, you won't have any help.
I'll let my colleagues explain how to create properties and how to get them back.
I would be more on this option, because I don't work with the direction of the thread in relation to the length, I assign a variable "long thread" or "short thread" in my flow sheets
Typically, you would create a custom property form and link a debit sheet entry to that property. You will then have to check this box for each piece created that has a short wire.
I don't know much about custom properties and since I opt for the other option, I can't help you much more with this one.
