Altium Designer - Room Definitions? Beginner here

[somuchtyler]

Hello, I am trying to make something in Altium Designer and whenever I run my Design Rule check it complains about all my components violating room definitions. I have absolutely no idea how to fix this, I have been googling for what seems like days...

Two options, say duck it and delete the rooms if you are not using them.
Or
Make sure your rooms are appropriately placed on top of the components. A few tips,
By default the parts move if the room moves be careful it may mess stuff up.
Components in the room definition can be checked by double click the room and clicking the test query button then click on the number of matches to show the components in the room.

Uncheck "Generate Rooms" if you are not using them.

Can someone explain what rooms are actually for?

[tmadness]

simply put: rooms area way of bringing in design level (schematic) associative information into a PCB layout. By default, altium generates a room per schematic sheet. You can get rid of rooms if you don't want to use them. Rooms are the way may design automation tasks are performed.

One use for them is multichannel designs. You put everything that gets repeated in a room, then duplicate the rooms as needed (with optional rotation). The one time I used AD for a multichannel design (~10 years ago) this was the way to do it. Every other time, rooms just get in my way.

Multichannel designs are probably the only time rooms are useful for most people.  You can also use them to define areas where rules can deviate from the default, for example allowing tighter clearances in the escape routing of a challenging package.  Unfortunately, like so many aspects of Altium, they're a good idea with a pretty crummy implementation and are often more trouble than they're worth.
