To whom it may concern: Seeking information on Flow Patterns for inner layers. 1.) What type of patterns are being used?. i.e. cross hatch, diamond, dot pattern etc. 2.) Any special benefit for using a specific flow pattern? 3.) Any positive or negative issues to be aware of. Please let me know if you need additional information to answer my questions. Thank you.
