Hello All
I find using rooms especially helpful for poorly drawn schematics. Many
designers I work with today will place 5 or six components bearing one
function together on page one and though these parts may tie into a
functional block on page 11, it difficult to decipher how a poorly drawn
schematic will flow. Unlike groups, I have the flexibility to move parts
more freely, however I wish I could place a room and all of the components
inside the room would automatically be placed into a component class. I
have also used the rooms for illustration purposes when I had to conduct
floor planning reviews. I label the rooms using the engineers functional
name and his electrical flow is very intelligible for a design review.
But what do I know I'm just another idiot asking for more idiotic features.
