Model Builder - preconditions

I am building a procedure using the model builder, but I have a problem with some tools that require the feature class to be created previously, and sometimes even showing in the table of contents of my project.
I have tried setting the preconditions but it still won't work.

I've had this problem up to now with "select attributes" and with "join fields". Is there any way to set the model for this to work?
