When placing families in a project most everyone knows that you can go to the command you need to place a file. For example if you want to draw a wall then you go to the wall command, if you want to place a component then the component command. That is pretty self explanatory, however not everyone knows you can use the project browser to place families. Simply go down to the families area, browse the family type you need and drag it onto the screen, if that family is a type that can be used directly into a command then it will start that command. If you try to drag a baluster or elevation symbol on screen it wont really do anything, if you drag any tag family onto the screen then it starts the tag command and it doesn’t matter which tag you drag.
