Detection of component hole gaps for weld beads in a computer-implemented solid modeling system

A computer-implemented solid modeling system that determines whether a gap exists between components based on internal loops of the components, and then generates a fillet or groove weld bead that fills the gap between the components. The gap is a component hole gap between components where one or more internal loops of a first component fully or partially encircles a second component, and the valid internal loops identify whether the second component passes through the first component through the component hole gap.
