 - The problem can generally be solved by applying electrical design toolbox and modifying based on desired material shape.
 
-- Applying existed electrical design toolbox allows the interface have capability to do routing and PCB design quickly. More algorithm requirements are expected along the project proceed.
+- Applying existing electrical design toolbox allows the interface to have the capability to do routing and PCB design quickly. More algorithm requirements may need to be developed later.
