Step 4: Interface Creation
Interfaces have to be created for every functional surface - so every surface where a boundary condition is applied to. With this Tool an offset to the inside with the input “Interface Thickness”(Non-Design Space) and an offset to the outside with the input
...
“Machining Allowance” is created. The Offset Distance is expanding the Interface to the set value to create material on front faces.
Three Interfaces are created to insert screws and fixate the Bookshelf to the wall. Therefore, an Interface Thickness of 2 mm and a Machining Allowance of 1 mm is entered. Because not only the inner faces touching the screw but also the front and back face are supposed to contain material and have sharp, functional faces, an Offset Distance of 3 mm is entered. Now select the inner surfaces of the fixation and confirm the selection (MMB).
One Interface is created on the top plate to use this as the book storage. Therefore, an Interface Thickness of 1mm and a Machining Allowance of 1mm is entered. Now select the top plate and confirm the selection (MMB).
