New to PCB - I think i'm over my head

I have a relative simple use case - Custom keyboard/matrix design with a Raspberry Pico. I'm doing my best with ChatGPT and i'm just struggling to no avail on matching the 3D step models with appropriate footprints etc. Am i missing a big piece of the puzzle, is there somewhere to get the needed files? Basically trying to build a button box with 37 switches, 2 rotary encoders and a couple of potentiometers. Its a nightmare trying to identify all the schematics and soource parts. Am I alone??????????????????? Help please! I've got the schematics all figured out, but the PCB design is killing me.

New system but no negative pressure?!?

Just got a system installed today. Before the tech left, he showed me the manometer. It’s both at zero and zero. See picture. From the Phan there is a downspout with a T one of the tease goes into a perimeter drain on the exterior of my house the other tea comes into my house in a crawlspace, which has been sealed with plastic. Is it normal to show a 0-0 reading on the manometer at this point?

UPDATE: Tech just left, suction now at .5 (Good enough i assume?). Turns out he put the T in the system above the exaust of the fan vs below it, so basically was just blowing air from my perimeter drain into my crawl space. He had closed the valve so much that there wasn't a noticable bubble undder the plastic, but thats likely why it was showing no pressure .....

Front Desk of company acknowledged that the notch was of concern and is looking at best option for remidiation. They're being very professional, but the tech seems to be abit of a guber.
