This tool would fit best into the menu 'Solid' -> 'Modify'.
Idea name:
3D flood tool
Function:
Fills a confined 3 dimensional space from which a new body/component is created.
Similar concept to 2D fill tools.
Use:
Create a negative or positive mold patterns.
Create a block out area.
Extra note:
Users would need to create boundaries where the flood cannot pass.
This could be blocking a hole in a body or creating 6 sides to make a box (for negative molding).
Extension to created a simulation:
When filling a space it could simulate filling a gas space (air) and modeling the flow of the filling liquid.
It could simulate the consumption of other non-gas areas (perhaps foam or plastics) when filling and show how the fill would be affected.
