Half Life - Alyx - How To - meshwork, round tunnel cutouts - vis optimizations - fix collisions

While working on one of my maps for "The Air Exchange", I found a neat efficient way to make round tunnel/sewer cutouts.
Also showing how to optimize for vis calculation and fix some collision issues.
Hope you liked it. Any questions? Just comment.
Would you like to see more about vis optimizations/ vis issues?
