send your designer to MFG line for half year and rotation around the  
assembly line stations (not as observer, but shift worker - night  
shift usually tell better story).  good old days, even a lowly QA  
like me have to go through the drill 1st 6 month in IBM (on  top of  
my regular lab learning tasks).
on the sunny note, you are not alone.  I and others (Ingemar of  
Ericsson  for one) dealt with paper designers with white running  
shoes and tennis rackets on  their back or surf board on top of the  
car... generate good ppt, with excellent dwg (3D even better), if you  
ask the chap look under microscope his own chip design, he couldn't  
recognize his own creation.  With Covid, I guess remote designers  
just going to be flourish like mushrooms ;-).  welcome to the  
jungle.  Sorry if I hurt someone's feelings.  (with Inge somewhere  
riding his motorcycle, Bev hiding in the woods, many hang their hats  
on cottages, no one weed out bad design as usual... wide life rules  
IMHO).  good luck.
