My goal is simple and as I have seen, there are multiple methods to perform a mesh "cut" but most are examples using a simple cube or sphere object.
Being brand new to 3d prints, there is an object on thingverse that allows for customization of the design. I want to remix and improve this design by adding a simple opening "cut" in the strap buckles that is commonplace to allow strap insertion at an angle without having to rethread the entire thing (in addition to what the online customizer also allows me to adjust). Pretty simple stuff. Until I launched blender. :)
I want to cut about a 2-3mm diagonal line through the outer buckle on each side. As I understand it, the ways to do this are try to create cube objects, somehow transform it after rotating and moving (which I still cannot even figure out how to do easily) then using that object as a delete "template" to carve out that shape from my target. Or, theres the knife tool. Or, there's the knife "project". Or, there's the boolean way.
I use Photoshop extensively, I am not an artist but am very adept at photo and video editing etc. but not a CAD guy and I cannot seem to get this thing cut properly.
