I think the closest you can get is the .dxf importing. But there's nothing special about making architectural objects, it's just like anything else. You can make doors, windows, staircases, cornices, columns, arches, flying buttresses, anything you desire. You can set the measurements up the way you like as well.

Now if you want to work AutoCad style in Maya, work from the Top viewport and draw your layout on the grid, then place walls,etc. according to your layout. If you want to create buildings for pictues or animations Maya is fine, if you want to engineer buildings to be built you should use AutoCad.
