Fusion360 Question: How would I model this?

How would I model something like this in Fusion360? https://www.instagram.com/p/BZ11eNZnKk3/?taken-by=hendricks_design

Use Sculpt Workspace

I havent used fusion360 but any other CAD program i would create a block to represent the wood then create a bunch of angled planes that intersect followed by some cut/trim steps where they intersect.

OK. Can you go into any detail about this? My experience with sculpt so far has only been with curved/smooth surfaces.

This seems like something a solid-modeler would not be good for. You would want a surface modeling app.

I think maybe the ‘Crease’ command might be of use to you.
